Is Nest considered a smart thermostats?
Nest Learning Thermostat
The Nest Learning Thermostat (or Nest Thermostat) is a smart thermostat developed by Nest Labs and designed by Tony Fadell, Ben Filson, and Fred Bould. It is an electronic, programmable, and self-learning Wi-Fi-enabled thermostat that optimizes heating and cooling of homes and businesses to conserve energy.
Computer security
The increasing number of home automation devices such as the Nest thermostat are also potential targets.
Smart thermostat
The most advanced smart thermostats combine both: they are able to learn when each room of a house is normally occupied and automatically schedule the heating for that room appropriately. Currently, the only such system available for home use is Heat Genius.
Thermostat
The pneumatic thermostat was invented by Warren Johnson in 1895 soon after he invented the electric thermostat. In 2009, Harry Sim was awarded a patent for a pneumatic-to-digital interface that allows pneumatically controlled buildings to be integrated with building automation systems to provide similar benefits as direct digital control (DDC).
Nastran
NEi Nastran is a general purpose finite element analysis solver used to analyze linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. It is available on a variety of platforms including 32/64-bit Windows and Linux.
This software was acquired by Autodesk in May 2014.
NX Nastran resulted from an FTC action against MSC Corporation for alleged antitrust activity. The antitrust settlement allowed the 2003 purchase of a royalty-free, perpetual license for the MSC.Nastran 2001 source code by UGS. UGS was previously the Unigraphics division of EDS. Nastran's CAE capabilities were added to NX Unigraphics' CAD and other components to form the "EDS/UGS PLM Solutions" product life-cycle management suite. This product line was acquired by SIEMENS in 2007 and became "SIEMENS PLM Software".
Thermostat
A thermostat operates as a "closed loop" control device, as it seeks to reduce the error between the desired and measured temperatures. Sometimes a thermostat combines both the sensing and control action elements of a controlled system, such as in an automotive thermostat.
Smart thermostat
Many housing corporations and smart thermostat developers realize the potential of smart thermostats to save energy, and have developed programs to advance sustainability through smarter technology. Ecobee promotes a sustainable future through its "A Better Tomorrow" program, in which the company donates time, data, and technology to ensure a brighter future. As part of this program, in January 2018, ecobee donated 776 ecobee thermostats to the Toronto Community Housing Corporation (TCHC) to help the city of Toronto advance their climate change action plan. This donation helps to improve the TCHC's goal of providing healthy, safe, and sustainable homes for the people of Toronto.
Nest Learning Thermostat
The Nest Thermostat is built around an operating system that allows interaction with the thermostat via spinning and clicking of its control wheel, which brings up option menus for switching from heating to cooling, access to device settings, energy history, and scheduling. Users can control Nest without a touch screen or other input device
. As the thermostat is connected to the Internet, the company can push updates to fix bugs, improve performance and add additional features. For updates to occur automatically, the thermostat must be connected to Wi‑Fi and the battery must have at least a 3.7 V charge to give enough power to complete the download and installation of the update.
Medical thermometer
Thermistor
Thermistor elements are the most sensitive temperature sensors available. A thermistor is a semiconductor device with an electrical resistance that is proportional to temperature. There are two types of products.
•Negative temperature coefficient (NTC) devices are used in temperature sensing and are the most common type of thermistor. NTCs have temperatures that vary inversely with their resistance, so that when the temperature increases, the resistance decreases, and vice versa. NTCs are constructed from oxides of materials such as nickel, copper, and iron.
• Positive temperature coefficient (PTC) devices are used in electric current control. They function in an opposite manner than NTC in that the resistance increases as temperature increases. PTCs are constructed from thermally sensitive silicons or polycrystalline ceramic materials.
• There are several advantage and disadvantages to using an NTC thermistor thermometer.
• Advantages include their small size and high degree of stability. NTCs are also long lasting and very accurate.
• Disadvantages include their non-linearity, and unsuitability for use in extreme temperatures
Nanoleaf
Launched at the end of 2015, the Nanoleaf Ivy Smarter Kit is a voice-controlled lighting system. It is the company's first product with smart home automation and works with Siri voice control. The company lists it as the world's most energy efficient smart bulb.
Nest Labs
On May 7, 2014, German activist group Peng Collective released a parody website named "Google Nest", satirizing Google's privacy policies and practices with fake products imitating Google art style, supposedly created as a result "of an intensive period of studying user behavior" in response to the "public debate around privacy and government surveillance". The site described four purported new services lampooning Google's data gathering tendencies made possible with Nest's technology: "Google Trust, Google Hug, Google Bee" and "Google Bye", respectively a "data insurance" paid with personal data, a location service encouraging in-person emotional interactions, a "personal drone", and a memorial website created from automatically collected information.
Nest Labs
Nest Hello is a hardwired smart video doorbell with facial recognition. The device was originally slated to launch in February 2018 but was delayed until March in the United States. The Hello was launched in the UK in May 2018.
Smart thermostat
Another study conducted on the issue determined that the biggest problem for programmable thermostats was the human using it. The technology inside a programmable thermostat is no doubt one of the most important factors in determining whether or not the thermostat will be successful in saving energy. But an equally important factor is the human who is using the thermostat. Unfortunately, many people who own programmable thermostats do not know how to use the thermostat or are not using all of the features that are offered. One study conducted a number of interviews, surveys, and observations to determine that the vast majority of programmable thermostat owners are not using the thermostats for their intended purpose. An online survey showed that 89% of respondents do not use the schedule feature on their programmable thermostat. Other results from the interviews and surveys show that a large number of people have misconceptions about heating/cooling and the use of programmable thermostats. One misconceptions is people believing that heating all of the time is more efficient than scheduling the heat to turn off. Another misconception noted in the study is that turning down the thermostat does not substantially reduce energy consumption. These misconceptions reaffirm the idea that the programmable thermostat itself could have all of the necessary tools, but if the user does not use them or uses them incorrectly, then these thermostats will fail at saving energy.
Satellite imagery
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging instrument onboard Terra, the flagship satellite of NASA's Earth Observing System (EOS) launched in December 1999. ASTER is a cooperative effort between NASA, Japan's Ministry of Economy, Trade and Industry (METI), and Japan Space Systems (J-spacesystems). ASTER data is used to create detailed maps of land surface temperature, reflectance, and elevation. The coordinated system of EOS satellites, including Terra, is a major component of NASA's Science Mission Directorate and the Earth Science Division. The goal of NASA Earth Science is to develop a scientific understanding of the Earth as an integrated system, its response to change, and to better predict variability and trends in climate, weather, and natural hazards.The Meteosat-2 geostationary weather satellite began operationally to supply imagery data on 16 August 1981. Eumetsat has operated the Meteosats since 1987.Several satellites are built and maintained by private companies. These include:
Nest Labs
In June 2014, it was announced that Nest would buy camera startup Dropcam for $555 million. With the purchase, Dropcam became integrated with other Nest products; if the Protect alarm is triggered the Dropcam can automatically start recording, and the Thermostat can use Dropcam to sense for motion. Later that year, Nest acquired the hub service Revolv but did not continue its product line.
Amazon.com controversies
Amazon has since suppressed other Google products, including Google Home (which competes with Amazon Echo), Pixel phones, and recent products of Google subsidiary Nest Labs (despite the Nest Learning Thermostat having integration support for Amazon's voice assistant platform Alexa). In retaliation, Google announced on December 6, 2017 that it would block YouTube from the Amazon Echo Show and Amazon Fire TV products. In December 2017, Amazon stated that it intended to start offering Chromecast again, but , it has not actually done so. Meanwhile, Nest stated that it would no longer offer any of its future stock to Amazon until it commits to offering its entire product line.
Myfox
In 2015, Myfox launched two new products, the Myfox Home Alarm and Security Camera. In June 2015, the company entered the North American market. In September 2015, Myfox announced the Myfox Home Alarm’s compatibility with the Nest Learning Thermostat and Nest Protect: Smoke and Carbon Monoxide alarm. In October 2015, Myfox announced the Myfox Security Channel on IFTTT that connects the Myfox Home Alarm and Myfox Security Camera with recipes that allow for interaction between the products, apps and IoT devices.. In 2016, the company announced the availability of 24/7 professional monitoring. The company reached an agreement with Apple in February 2016, and is now available for sale at Apple stores in France, Germany, Spain, Italy, the United Kingdom, Sweden and Switzerland, as well as online in over twenty more countries.
Smart thermostat
According to the 2015 Residential Energy Consumption Survey conducted by the U.S. Energy Information Administration, home heating and cooling account for the highest percentage of residential electrical energy consumption. Air conditioning accounts for 17% of electrical usage while space heating accounts for 15%. The Residential Energy Consumption Survey from 2009 looked at energy consumption from all energy types (natural gas and electricity). This survey determined that space heating accounted for 42% of all residential energy consumption, while air conditioning accounted for 6%. This energy usage needed to heat and cool homes is directly linked to climate change, as the energy provided for heating and cooling often comes from the burning of fossil fuels, leading to the release of greenhouse gas emissions. With an added focus on combating climate change and global warming, nations from around the world have begun to take on this issue by limiting greenhouse gas emissions and preventing the rise in global temperature through agreements such as The Paris Agreement. Any steps taken to reduce residential energy consumption will help to achieve those goals.
Tony Fadell
While building his energy-efficient home near Lake Tahoe in California, Fadell went looking for a thermostat and was frustrated by the limited features of the devices available. Together with Matt Rogers, a former Apple colleague, he set out to redesign the traditional thermostat. In May 2010, Fadell and Rogers co-founded Nest Labs in Palo Alto, CA. Nest Labs, or Nest, is a company that designs and manufactures a sensor-driven, Wi-Fi-enabled, learning programmable thermostat, now in its third generation.
Embrace Innovations
The Embrace Nest, meant for use in hospitals, needs intermittent electricity. It can be used for transportation, in the Neonatal Intensive Care Unit (NICU), or in a maternity ward. The Embrace Care works with no electricity, periodically using hot water, and is intuitive enough to be used by a healthcare worker or a village mother. Embrace has received an ISO 13485 certification for their operations, and obtained a CE mark for their first product, Embrace Nest, meeting international regulatory standards.
Thermostat
Some programmable thermostats are available to control line-voltage systems. Baseboard heaters will especially benefit from a programmable thermostat which is capable of continuous control (as are at least some Honeywell models), effectively controlling the heater like a lamp dimmer, and gradually increasing and decreasing heating to ensure an extremely constant room temperature (continuous control rather than relying on the averaging effects of hysteresis). Systems which include a fan (electric furnaces, wall heaters, etc.) must typically use simple on/off controls.
Nest Labs
In 2016, Nest announced that the devices of Revolv customers would be bricked on May 15, as they were shutting down the necessary cloud software. Karl Bode and Emmanuel Malberg of "Vice News" compared the move to a remote deletion of purchased Xbox Fitness content by Microsoft. In February 2016, the Federal Trade Commission's Division of Advertising Practices opened an investigation into whether Nest Labs, Inc. violated Section 5 of the Federal Trade Commission Act, 15 U.S.C. § 45, in connection with Nest's decision to shut down the services necessary to operate its Revolv “Smart Home Hub”. All customers were offered full refunds and the investigation was closed On July 7, 2016.
Ecobee
The ecobee4 is ecobee's flagship product which was originally launched May 3, 2017. It is a touchscreen thermostat that works with up to 32 remote temperature/motion sensors to adjust the thermostat based on where you are. It also has IFTTT integration. An updated version of the ecobee3 was released in 2015 that works with Apple HomeKit. The ecobee3 lite was released on October 17, 2016. The ecobee3 lite is a less expensive thermostat that resembles the ecobee3, but does not include any remote temperature sensors. Support for remote temperature sensors was added to the ecobee3 lite in March 2017.
Tony Fadell
Anthony Michael "Tony" Fadell (born March 22, 1969) is an American engineer, inventor, designer, entrepreneur, and angel investor. He served as the Senior Vice President of the iPod division at Apple Inc., from March 2006 to November 2008 and is known as "one of the fathers of the iPod" for his work on the first generations of Apple's music player. In May 2010, he founded Nest Labs, which announced its first product, the Nest Learning Thermostat, in October 2011. Nest was acquired by Google in January 2014 for $3.2B. Since early 2015 he led the Google Glass division, until his resignation in June 2016.
Berendsen thermostat
Though the thermostat does not generate a correct canonical ensemble (especially for small systems), for large systems on the order of hundreds or thousands of atoms/molecules, the approximation yields roughly correct results for most calculated properties. The scheme is widely used due to the efficiency with which it relaxes a system to some target (bath) temperature. In many instances, systems are initially equilibrated using the Berendsen scheme, while properties are calculated using the widely known Nosé–Hoover thermostat, which correctly generates trajectories consistent with a canonical ensemble. However, the Berendsen thermostat can result in the flying ice cube effect, an artifact which can be eliminated by using the more rigorous Bussi–Donadio–Parrinello thermostat; for this reason, it has been recommended that usage of the Berendsen thermostat be discontinued in almost all cases except for replication of prior studies.
Nest Labs
Nest Labs is an American manufacturer of smart home products including thermostats, smoke detectors, and security systems including smart doorbells and smart locks. Its flagship product, which was the company's first offering, is the Nest Learning Thermostat that was introduced in 2011. The product is programmable, self-learning, sensor-driven, and Wi-Fi-enabled – features that are often found in other Nest products. It was followed by the Nest Protect smoke and carbon monoxide detector in October 2013. After its acquisition of Dropcam in 2014, the company introduced its Nest Cam branding of security cameras beginning in June 2015.
Nest Labs
Nest Cam Outdoor was announced in July 2016, and is a version of the Nest Cam adapted for outdoor monitoring. The main differences from the Nest Cam Indoor is in its design which is built to withstand outdoor conditions.
Nest Labs
On April 12, 2012, Nest publicly announced they will see Honeywell all the way to court as they believe that none of the seven allegedly infringed patents were actually violated. Honeywell is claiming that Nest has infringed on patents pertaining to remotely controlling a thermostat, power-stealing thermostats, and thermostats designed around a circular, interactive design, similar to the Honeywell T87. However, Honeywell held patents that were almost identical to those that expired in 2004. Nest has taken the stance that they will see this through to a patent court as they suspect Honeywell is trying to harass them, litigiously and financially, out of business.
Nest Labs
Nest Secure is a home security system announced in September 2017. The system consists of Nest Guard (an alarm, keypad, and motion sensor), Nest Detect (a door/window and motion sensor), and Nest Tag (a key chain fob). The product was released in November 2017. Nest also has a partnership with Brinks Home Security for a monthly plan so that the Nest Protect system can be professionally monitored.
Nest Labs
A weatherproof outdoor model was announced in September 2017. The indoor version of the Cam IQ also received an update to add Google Assistant functionality to the device in 2018.
Nansen bottle
A modern variation of the Niskin bottle uses actuated valves that may be either preset to trip at a specific depth detected by a pressure switch, or remotely controlled to do so via an electrical signal sent from the surface. This arrangement conveniently allows for a large number of Niskin bottles to be mounted together in a circular frame termed a "rosette". As many as 36 bottles may be mounted on a single rosette. Thermistor temperature sensors are more commonly employed on Niskin bottle rosettes due to their higher accuracy compared to mercury thermometers.
Tado°
In June 2015 tado° launched its second product, the Smart AC Control. It is not a thermostat. It turns any air conditioning unit into a smarter device. tado° Smart AC Control uses a smartphone's location to be able to determine if the resident is at home or not and automatically turns the AC on or off. The air conditioner can also be manually operated via the Smart AC Control using the tado° App.
Schlage
Nexia Home Intelligence is a home automation system that was launched by Schlage and Ingersoll Rand that allows users to remotely control and monitor home automation devices. A wireless network is created within the home and connects the wireless door lock to the internet. Using a smart-phone or a web-enabled computer, users can monitor and send commands to the Schlage Bridge, which communicates with Z-Wave enabled wireless locks, thermostats, lights, cameras, and other components within the home.
Thermostat
Possibly the earliest recorded examples of thermostat control were built by the Dutch innovator Cornelis Drebbel (1572–1633) around 1620 in England. He invented a mercury thermostat to regulate the temperature of a chicken incubator. This is one of the first recorded feedback-controlled devices.
Nest Learning Thermostat
The operating system itself is based on Linux 2.6.37 and many other free software components.
To comply with the terms of the GPLv3 license under which some components are available, Nest Labs also provides a special firmware image which will unlock the system so that it will accept arbitrary code sent to it.
Thermostat
HVAC systems with the ability to modulate their output can be combined with thermostats that have a built-in PID controller to achieve smoother operation.
There are also modern thermostats featuring adaptive algorithms to further improve the inertia prone system behaviour. For instance, setting those up so that the temperature in the morning at 7 a.m. should be 21 °C (69.8 °F), makes sure that at that time the temperature will be 21 °C (69.8 °F), where a conventional thermostat would just start working at that time. The algorithms decide at what time the system should be activated in order to reach the desired temperature at the desired time. Other thermostat used for process/industrial control where ON/OFF control is not suitable the PID control can also makes sure that the temperature is very stable (for instance, by reducing overshoots by fine tuning PID constants for set value(SV) or maintaining temperature in a band by deploying hysteresis control.)
Nest Labs
In September 2017, Nest released the Thermostat E, a lower-priced version of the original Nest Thermostat. It is similar in functionality to the standard model, except with a plastic, ceramic-like bezel ring (instead of metal) and a "frosted" overlay for its display. Unlike the original, the screen only activates when the device is being used; these design changes are intended to make the device appear more natural within a home. The Thermostat E also does not feature as many wiring connectors as the higher-end model; Nest stated that this would make it support at least 85% of homes (as opposed to 95% for the standard model).
Thermostat
A thermostat is a component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint.
OpenHAN
Perhaps reflecting utility influence, OpenHAN was one of the original NIST smart grid standards sanctioned for by the North American Electric Reliability Corporation (NERC). Unlike most other networking standards, it uses in-home wiring between AC-powered devices. It primarily relies on AC powerline networking as defined by IEEE 1901 and packet management under ITU G.hn. The closest DC equivalent is power over ethernet (PoE). These are used for smart thermostats and other smart appliances, put power and data all on one wire, and similarly have about one gigabit capacity. Unlike PoE which requires cat5 or cat6 ethernet wiring redundant with the AC wiring, OpenHAN makes use of all existing wire (AC outlets, cable coax and telephone cat3).
SmartThings
SmartThings Labs was introduced in January 2014 as an area within the native app which allows users to access a series of projects that are being built by either the internal SmartThings team or a community of developers. These projects are still being worked on in production and are meant to give customers early access to upcoming product integrations. For example, SmartThings customers can access Labs to control their ecobee thermostats, Belkin WeMo switches, Quirky Pivot Power Genius, Sonos, Philips hue bulbs, and TCP light bulbs directly from the SmartThings app, and also to trigger these products to adjust when various actions take place.
Nest Learning Thermostat
A special version of Nest is available in Europe, which is capable of controlling 230 volt heating systems. The Nest is paired with a "Heat Link" device, which contains the circuitry required for controlling the mains-voltage heating system. The first release was the 2nd Generation Nest thermostat which the Heat Link controlled the central heating boiler. The 3rd Generation added support for OpenTherm and for controlling domestic hot water. The Nest E was made available to the UK in October of 2018. It has several major changes as the thermostat is stand mounted only, the Heat Link is grey and battery powered, the Heat Link loses the domestic hot water support, and lastly designed to be installed on the wall where the old thermostat was located.
SMART home technology
SMART home technology devices can range in the following:As of 2015, the most common piece of SMART home technology in the United States were wireless speaker systems with 17 percent of people having one or more. SMART thermostats were the second most prevalent piece of SMART home technology with 11 percent of people using the device. A 2012 consumer report that pulled data from the "National Association of Home Builders" looked for what SMART home devices homeowners wanted most and found that top five were wireless security systems (50%), programmable thermostats (47%), security cameras (40%), lighting control systems and wireless home audio systems (39%), and home theater and multi-zone HVAC systems (37%).
Smart thermostat
Another popular way that utility companies promote switching to a smart thermostat is through monetary incentives. The San Diego Gas & Electric company currently runs a program that offers participants a $50 e-gift card after switching to a smart thermostat. The Wisconsin Focus on Energy program partners with utility companies across Wisconsin to offer a $75 check to those who purchase a qualifying smart thermostat. Austin Energy, a utility company providing electricity to the city of Austin, Texas, offers a $25 rebate for each eligible smart thermostat that is purchased and installed. Many other companies across the United States offer similar programs to incentive smart thermostats and more sustainable heating and cooling.
Smart thermostat
As a result of these studies and others like them, energy star suspended its labelling of programmable thermostats in December 2009. It became the goal of smart thermostats to address these issues by taking the human out of the picture and creating a thermostat that uses smart computing to truly reduce energy usage and cost.
Smart thermostat
There are other factors that cause discrepancies even between studies that all look at actual data. Most studies compare total energy consumption of a house from year to year to determine energy savings, as opposed to looking at just the energy that is used for heating and cooling. Due to this, there could be other factors that change the energy consumption of a house, and it might be incorrect to state that the thermostat is responsible for all energy savings in a house. For example, it is possible that other new energy efficient practices/appliances are partially responsible for the savings in addition to the thermostat.
Smart thermostat
A Connected thermostat is one that can be controlled through an internet connection, but will not provide analytic information. In recent years WI-FI thermostats have risen in popularity, they combine the technology of thermometers and WI-FI. So now you can have a thermometer in your home that is displayed on your phone that uses Wi-Fi technology. This technology is being developed right now so it will be available for thermostats in machinery and cars. Google are involved in this push towards technology since they acquired a Wi-Fi temperature company called Nest.The market of smart thermostats is expected to reach around 3.5 Billion USD by the end of the year 2022.
Google Home
Google Home includes home automation features, enabling owners to use it as a central hub to control smart devices. Examples of supported devices include the Chromecast digital media player, and products from Nest, SmartThings, Philips Hue, LIFX, LightwaveRF, and Logitech Harmony.
Smart thermostat
Like a connected thermostat, they are connected to the Internet. They allow users to adjust heating settings from other internet-connected devices, such as a laptop or smartphones. This allows users to control the thermostat remotely. This ease of use is essential for ensuring energy savings: studies have shown that households with programmable thermostats actually have higher energy consumption than those with simple thermostats, because residents program them incorrectly or disable them completely.
Nest Learning Thermostat
While the thermostat software by Nest Labs itself remains proprietary, a third party has reimplemented the basic logic in an open source replacement called FreeAbode.
Nest devices interconnect with each other using a protocol called Weave, which is based on IEEE 802.15.4 and Wi-Fi 802.11 b/g/n.
SmartStax
SmartStax is a brand of genetically modified seed made through a collaboration between Monsanto Company and Dow Chemical Company. It takes advantage of multiple modes of insect protection and herbicide tolerance. SmartStax takes advantage of Yieldgard VT Triple (Monsanto), Herculex Xtra (Dow), RoundUp Ready 2 (Monsanto), and Liberty Link (Dow). The traits included protect against above-ground insects, below-ground insects, and provide broad herbicide tolerance. It is currently available for corn, but cotton, soybean, and specialty crop variations are to be released. Previously, the most genes artificially added to a single plant was three, but Smartstax includes eight. Smartstax also incorporates Monsanto's Acceleron Seed Treatment System which protects against insects at the earliest stages of development. Smartstax is sold under the Genuity (Monsanto) and Mycogen (Dow) brands.
Smart mattress
The smart mattress is a mattress that has sensors to monitor sleep patterns. Major vendors include Eight Sleep, Kingsdown, Responsive Surface Technology, and Sleep Number. Products can take the form of mattress covers, mattress pads, or the entire mattress.
Nest Labs
Nest × Yale is a smart lock that is connected to the Internet. It was released in 2018. It is connected to Nest Connect or Nest Guard to enable it. Nest collaborated with Yale Locks for this project.
Thermostat
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control, to such as automotive coolant control. Thermostats are used in any device or system that heats or cools to a setpoint temperature, examples include building heating, central heating, air conditioners, as well as kitchen equipment including ovens and refrigerators and medical and scientific incubators.
Nest algebra
In functional analysis, a branch of mathematics, nest algebras are a class of operator algebras that generalise the upper-triangular matrix algebras to a Hilbert space context. They were introduced by and have many interesting properties. They are non-selfadjoint algebras, are closed in the weak operator topology and are reflexive.
Sentroller
Many of the new things connected to the Internet will be Sentrollers. Sentrollers are either actuators, sensors, controllers, or combinations of these three things. One simple example is a home thermostat. A thermostat is a sentroller as it senses the temperature in the home, checks whether the home or room in which the thermostat is monitoring temperature is at the desired temperature, and if not, turns on the heater or the air conditioner. Therefore, a thermostat is a sensor and a controller – a sentroller. No human interaction with the thermostat or the cloud will be necessary for the thermostat to keep the heat in the home at the right level.
Nest (magazine)
Marketed as an interior design magazine, and edited by Joseph Holtzman, "Nest" generally eschewed the conventionally beautiful luxury interiors showcased in other magazines, and instead featured photographs of nontraditional, exceptional, and unusual environments. Fred A. Bernstein, writing in "the New York Times", wrote that Joseph Holtzman "believed that an igloo, a prison cell or a child's attic room (adorned with Farrah Fawcett posters) could be as compelling as a room by a famous designer." During its run, "Nest" showed the room of a 40-year-old diaper lover, the lair of an Indonesian bird that decorates with colored stones and vomit, the final resting place of Napoleon’s penis, the quarters of Navy seamen, a barbed-wire-trimmed bed that doubled as a tank, and a Gothic Christmas card from filmmaker John Waters. Noted architect Rem Koolhaas called it "an anti-materialistic, idealistic magazine about the hyperspecific in a world that is undergoing radical leveling, an 'interior design' magazine hostile to the cosmetic." Artist Richard Tuttle was quoted as saying that Mr. Holtzman "channeled the collective unconscious, to give us the pleasure of ornament before we even knew we wanted it."
Smart thermostat
Another discrepancy to consider is the population of people involved in the study. Some studies, such as the MyEnergy study, involve people who signed up for an energy analysis program. These people are likely to be more energy conscious and efficient and have better heating and cooling practices. This greater interest in energy efficiency may lead to lower energy savings by switching to a smart thermostat. The most energy conscious customers are the ones more likely to have had efficient thermostat settings, therefore, the savings that they receive from the smart thermostat may not be as great.
Smart meter
It also is important for smart grid implementations that power line communication (PLC) technologies used within the home over a Home Area Network (HAN), are standardized and compatible. The HAN allows HVAC systems and other household appliances to communicate with the smart meter, and from there to the utility. Currently there are several broadband or narrowband standards in place, or being developed, that are not yet compatible. To address this issue, the National Institute for Standards and Technology (NIST) established the PAP15 group, which studies and recommends coexistence mechanisms with a focus on the harmonization of PLC standards for the HAN. The objective of the group is to ensure that all PLC technologies selected for the HAN coexist as a minimum. The two main broadband PLC technologies selected are the HomePlug AV / IEEE 1901 and ITU-T G.hn technologies. Technical working groups within these organizations are working to develop appropriate coexistence mechanisms. The HomePlug Powerline Alliance has developed a new standard for smart grid HAN communications called the HomePlug Green PHY specification. It is interoperable and coexistent with the widely deployed HomePlug AV technology and with the new IEEE 1901 global standard and is based on Broadband OFDM technology. ITU-T commissioned in 2010 a new project called G.hnem, to address the home networking aspects of energy management, built upon existing Low Frequency Narrowband OFDM technologies.
Smart meter
The United Kingdom roll-out is considered to be the largest programme ever undertaken, involving visits to 30 million homes and 2 million small businesses to replace meters for both gas and electricity. Most households will have smart meters installed by their energy company before 2020. At the end of 2013 there were 295,700 smart meters installed in domestic properties in Great Britain. In March 2016, figures released by the Department for Energy and Climate Change showed that only 2.3 million smart meters had been installed in UK homes. This was well behind schedule to hit the government’s target to have 50 million in place by 2020. As of August 2018, 11 million SMETS1 devices were functioning normally, with 637,000 in "dumb" mode, according to the government. 42 million remained to be installed by the 2020 deadline.
Smart thermostat
Manual thermostats (also known as analog thermostats) are the oldest and simplest type of thermostats. These thermostats are set to one temperature and do not change until the user manually adjusts the temperature.
Programmable thermostats, first introduced in the 1970s, are a type of thermostat that allows the user to set a schedule for different temperatures at different times. Most programmable thermostats also have a hold feature which suspends the schedule and effectively turns the thermostat into a manual thermostat. The idea of the scheduling feature is that users will set a warmer or cooler temperature when the home is unoccupied to save energy and money. Due to this assumed energy savings, some building codes and government programs began requiring the use of programmable thermostats. Unfortunately, due to human error in using these devices, many programmable thermostats result in more energy use than the basic manual thermostat.
Tado°
Besides reducing energy consumption and increasing savings the thermostat also considers the residents' overall comfort. tado° detects the absence or presence of residents via smartphone and then adjusts the heating automatically. Weather forecasts and the heating properties of a home such as insulation are taken into account.
Nest Labs
Co-founded by former Apple engineers Tony Fadell and Matt Rogers in 2010, the company quickly expanded to more than 130 employees by the end of 2012. Google acquired Nest Labs for US$3.2 billion in January 2014, when the company employed 280. As of late 2015, Nest employs more than 1,100 and has a primary engineering center in Seattle.
Honeywell
On December 29, 2015 Honeywell completed the sale of Elster for US$5.1B (announced on July 28, 2015) entering the space of gas electricity and water meters with a specific focus on smart meters and hoped to be a growth driver for Honeywell in 2016 and beyond. The deal also complements the HON Combustion business with the addition of Elster with strong brands such as Kromschroeder and Eclipse. Honeywell International Inc. then acquired the 30% stake in UOP Russell LLC it didn't own already for roughly $240 million in January 2016. In February, Honeywell entered into a definitive agreement to acquire Xtralis, a leading global provider of aspirating smoke detection along with advanced perimeter security technologies and video analytics software, for $480 million from funds advised by Pacific Equity Partners and Blum Capital Partners. The deal was completed on April 1, 2016. In May 2016, Honeywell International Inc. settled its patent dispute regarding Google subsidiary Nest Labs, whose thermostats Honeywell claimed infringed on several of its patents. Google parent Alphabet Inc. and Honeywell said they reached a "patent cross-license" agreement that "fully resolves" the long-standing dispute. Honeywell sued Nest Labs in 2012. On September 12, 2016, Morris Plain, N.J.-based Honeywell announced that it would invest $20 million in the first-of-its-kind software development center and relocate the headquarters of its nearly $10 billion home and building technologies division from suburban Minneapolis to Atlanta. The expansion will add more than 800 jobs.

The NEST group is housed in an integrated suite of staff offices, general-purpose laboratory space and class 100/1000 cleanrooms and is a founder member of the Manchester Centre for Mesoscience and Nanotechnology where the ground-breaking, Nobel Prize–winning work on Graphene by Andre Geim and Konstantin Novoselov was undertaken. The group is led by Professor Thomas Thomson, academic staff members include Professor Jim Miles, Ernie W Hill, Milan Mihajlovic and Paul W Nutter.
KM3NeT
For the design of the neutrino detector, KM3NeT builds on the experience of three pilot projects in the Mediterranean Sea: the ANTARES detector, the Neutrino Mediterranean Observatory (NEMO) project and the NESTOR Project. The NEMO and NESTOR projects both did research and development work for a neutrino telescope, but said telescopes were never built (apart from some small prototypes). ANTARES telescope was completed on 30 May 2008, and is the largest neutrino telescope in the northern hemisphere. In the southern hemisphere, at Antarctica, the IceCube Neutrino Observatory is already operational. Together, IceCube and KM3NeT will view the full sky and form a global neutrino observatory.
Griddle
Snap action thermostats are the most common control used in heavy duty commercial griddles with medium-to-heavy production demands. These controls are called “snap action” because the control mechanism will turn the burner valve or electrical element fully on or completely off, with no modulation or intermediate heat source operation – effectively ‘snapping’ the heat source on or off. While not as responsive as solid state controls, snap action controls can maintain a griddle surface temperature within +/- 15°F (8°C) of set point if the thermostat bulb is embedded assuming a 1-inch (25mm) thick steel plate. This operating temperature range may be pushed to +/- 20 to 25°F (10°C to 13°C) if the probe is bottom mounted due to the additional thermal hysteresis introduced by the plate material.

Griddle
Thermostats are used to regulate the griddle surface around a temperature set point established by the operator. Ranges of operation can vary depending on the controls used and the construction of the griddle, but is most common.
Other than solid state controls, which are very sensitive across their entire range of control, snap-action and modulating (aka – throttling) thermostats have peak sensitivity across the middle two-thirds of their operating range. This can limit their overall performance at the low end of their temperature spectrum (at or below ). This is due to the nature of the temperature control mechanism, which consists of a fluid-filled bulb (typically an oil) connected to the thermostat control via a long narrow capillary tube. The fluid in the bulb expands and contracts with temperature, activating a control response from the thermostat. There is a time lag between sensing the temperature change from the surface of the griddle plate to the response of the fluid within the bulb, to the thermostat control and turning the heat source on or off, up or down. This lag is referred to as hysteresis, and is a primary aspect of recovery time – an important griddle performance metric.
Nest Learning Thermostat
The device is based on a machine learning algorithm: for the first weeks users have to regulate the thermostat in order to provide the reference data set. The thermostat can then learn people's schedule, at which temperature they are used to and when. Using built-in sensors and phones' locations, it can shift into energy saving mode when it realizes nobody is at home.
Programmable thermostat
Some digital thermostats have the capability of being programmed using a touch-tone telephone or over the Internet, such as the Nest Learning Thermostat.
Vivint
In January 2016, Vivint announced partnerships with Amazon and Nest. Vivint also announced Vivint Element, its own smart thermostat, and the Vivint Ping Camera, the first indoor camera with one-touch call out.
Norbest
Recognizing the homemaker's need for more convenient products, Norbest again became the leader in new product development in the 1960s and 1970s. Norbest was first with the Tender-Timer pop-up cooking gauge that pops its stem at precisely the time when the turkey is done. Norbest also led the way with pre-basted turkeys and bone-in breasts, and with boneless roasts and other products.
Smart thermostat
One of the issues with programmable thermostats that smart thermostats try to fix is the confusing user interface. Many owners of programmable thermostats found the controls and directions to be too confusing and opted out of using the scheduling feature completely. Others who used the feature used it incorrectly, due to the confusing directions, and saw an increase in energy usage. Developers of smart thermostats have attempted to fix this issue by creating simple to use thermostats and providing proper direction. While this is an improvement on programmable thermostats, studies have shown that users desire more intense training from the installer of the thermostat on how to use the technical features. Additionally, many smart thermostats use a web portal where users can adjust the thermostat settings and look at their energy usage history. Again, studies have shown that users want this feature to be improved. Some complain that the web portal is not user friendly and they desire more training on how to use the web features during installation.
Thermostat
Thermostats are used in any device or system that heats or cools to a setpoint temperature, examples include building heating, central heating, air conditioners, HVAC systems, water heaters, as well as kitchen equipment including ovens and refrigerators and medical and scientific incubators. In scientific literature, these devices are often broadly classified as thermostatically controlled loads (TCLs). Thermostatically controlled loads comprise roughly 50% of the overall electricity demand in the United States.
Smart thermostat
Motion detectors can determine if someone is home. One smart thermostat that uses motion detectors is the Ecobee4.
Nearables
In August 2014 Estimote Inc. launched Estimote Stickers: a new generation of small Bluetooth Smart-based beacons. The term ‘nearables’ was inspired by wearable computers which were gaining increasing popularity throughout 2013 and 2014 thanks to products like Pebble smartwatch and Google Glass. Originally, the nearables were described as "smart, connected objects that broadcast data about their location, motion and temperature".
Nest Labs
In May 2016, an employee filed an unfair labor practice charge with Region 32 of the National Labor Relations Board against Nest and Google. In the charge, the employee alleged that he was terminated for posting information about Tony Fadell's poor leadership to a private Facebook page consisting of current and former employees. The charge also alleged that Nest and Google had engaged in unlawful surveillance and unlawful interrogation of employees in order to prevent them from discussing the work environment at Nest.
Smart meter
The company Oxxio introduced the first smart meter for both electricity and gas in the Netherlands in 2005. In 2007, the Dutch government proposed that all seven million households of the country should have a smart meter by 2013, as part of a national energy reduction plan.
Thermostat
Thermostats use different types of sensors to measure the temperature. In one form, the mechanical thermostat, a bimetallic strip in the form of a coil directly operates electrical contacts that control the heating or cooling source. Electronic thermostats, instead, use a thermistor or other semiconductor sensor that requires amplification and processing to control the heating or cooling equipment. A thermostat is an example of a "bang-bang controller" as the heating or cooling equipment output is not proportional to the difference between actual temperature and the temperature setpoint. Instead, the heating or cooling equipment runs at full capacity until the set temperature is reached, then shuts off. Increasing the difference between the thermostat setting and the desired temperature therefore does not change the time to achieve the desired temperature. The rate at which the target system temperature can change is determined both by the capacity of the heating or cooling equipment to respectively add or remove heat to or from a target system and the capacity of the target system to store heat.
Smart thermostat
Another major feature of smart thermostats is their ability to connect to the internet. Smart thermostats are designed with a WiFi module that allows the thermostat to connect to the users home or office network and interface with a web portal or smartphone application, allowing users to control the unit remotely. The WiFi feature also has the ability to send reports on energy usage and HVAC system performance via the web portal, informing the user on their energy efficiency and how it compares to other smart thermostat users. It also alerts users when a problem arises with their HVAC system or when it is time for equipment maintenance. The thermostat also uses the WiFi connection to display current weather conditions and the weather forecast.
Smartdust
Smartdust is a system of many tiny microelectromechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light, temperature, vibration, magnetism, or chemicals. They are usually operated on a computer network wirelessly and are distributed over some area to perform tasks, usually sensing through radio-frequency identification. Without an antenna of much greater size the range of tiny smart dust communication devices is measured in a few millimeters and they may be vulnerable to electromagnetic disablement and destruction by microwave exposure.
Shasta Ventures
Shasta Ventures and Kleiner Perkins Caufield & Byers were the only investors in the Series A round for Nest Labs (the home automation company) in September 2010. When Google later bought Nest Labs for US$3.2 billion in January 2014, Shasta had a net gain of about $200 million, enough to pay out "almost all" of the $250 million Shasta II fund.
TRI Pointe Group
In 2018, Quadrant teamed up with Amazon to expand its HomeSmart™ technology offerings. Quadrant added Amazon’s Alexa to its program, offering homebuyers resources such as Echo Show, Echo Dot and Echo Spot. The HomeSmart package already offered Ring Pro doorbells, Nest 3 Thermostats, Caseta Lighting Controls and other in-home technology devices.
Nest Learning Thermostat
The Nest Temperature Sensor was added in March, 2018. Up to six of these battery operated devices can be added to a single thermostat to provide remote temperature monitoring. Nest will then use the appropriate sensor based on schedule. Since they use Bluetooth Low Energy they are only compatible with the E and 3rd generation thermostats.
Smart device
A smart device is an electronic device, generally connected to other devices or networks via different wireless protocols such as Bluetooth, NFC, Wi-Fi, LiFi, 3G, etc., that can operate to some extent interactively and autonomously. Several notable types of smart devices are smartphones, smart cars, smart thermostats, smart doorbells, smart locks, smart refrigerators, phablets and tablets, smartwatches, smart bands, smart key chains, smart speakers and others. The term can also refer to a device that exhibits some properties of ubiquitous computing, including—although not necessarily—artificial intelligence.
Butterfleye
Nader described Butterfleye as "Dropcam meets Nest," a combination of streaming cameras and home automation technology. Butterfleye's cameras are wireless with an estimated two-week battery life, allowing them to continue functioning in case of power interruptions.
Smart thermostat
Smart thermostats could be a solution to reducing energy consumption, as numerous studies have shown that these thermostats do in fact reduce home energy consumption. Additionally, the technology within smart thermostats has proven to provide optimal occupant comfort, while still reducing energy consumption. In addition to providing comfort, these technologies take the human out of the picture. Many sustainable devices rely heavily on how the user uses them. By relying on technology instead of human actions, smart thermostats reduce the amount of human error often experienced with other sustainable devices, such as the programmable thermostat. These factors suggest that installing a smart thermostat is one easy step than many people can take to reduce energy usage and greenhouse gas emissions, ultimately leading to a more sustainable future.
Deadband
Simple (single mode) thermostats exhibit hysteresis. For example, the furnace in the basement of a house is adjusted automatically by the thermostat to be switched on as soon as the temperature at the thermostat falls to 18 °C and the furnace is switched off by the thermostat as soon as the temperature at the thermostat reaches 22 °C. There is no temperature at which the house is not being heated or allowed to cool (furnace on or off).
Programmable thermostat
More expensive models have a built-in PID controller, so that the thermostat learns how the system will react to its commands. Programming the morning temperature to be 21° C at 7:00 AM, for instance, makes sure that at that time the temperature will be 21 °C. A standard programmable thermostat would simply start working toward 21° at 7:00 AM. The PID controller decides at what time the system should be activated in order to reach the desired temperature at the desired time. It knows this by remembering the past behavior of the room, and the current temperature of the room. This is called optimal start.
LIFX
When a Nest Learning Thermostat notices that the home is unoccupied, LIFX bulbs can be configured to switch themselves on and off throughout the day to make it seem like someone is home.
Nest Learning Thermostat
Many have commented on the company's "Nest Community" regarding the lack of prominent display of the current temperature.
Nest Labs
The Nest Thermostat is built around an operating system that allows interaction with the thermostat via spinning and clicking of its control wheel, which brings up option menus for switching from heating to cooling, access to device settings, energy history, and scheduling. Users can control Nest without a touch screen or other input device. As the thermostat is connected to the Internet, the company can push updates to fix bugs, improve performance and add additional features. For updates to occur automatically, the thermostat must be connected to Wi‑Fi and the battery must have at least a 3.7 V charge to give enough power to complete the download and installation of the update.
Vivint
In 2017, Vivint announced a partnership with Airbnb. It also integrated its smart home suite with Google Home and Philips Hue smart lighting. In 2018, Vivint collaborated with Google to include two Google Home Mini devices in every starter kit. The company also integrated the Nest Thermostat E and Google Wifi to its smart-home suite.
Nest Labs
On May 14, 2013, Allure Energy, Inc. ("Allure") was issued a patent by the USPTO titled "Auto-Adaptable Energy Management Apparatus." The very same day, Allure filed a lawsuit against Nest and two other defendants in the Eastern District of Texas alleging Nest was infringing their newly issued patent; the lawsuit is ongoing.
Nestlé
Since 2011, Nestlé is the only infant formula manufacturer to have met the 104 criteria on the marketing of breast milk substitutes (FTSE4Good BMS Criteria) of the FTSE4Good Responsible Investment Index. Nestlé's inclusion in the index is based on results of independent and transparent verifications conducted by PricewaterhouseCoopers every 18 months. Every year since 2009, Bureau Veritas conducts independent assurance of compliance with the Nestlé Policy and Instructions for Implementation of the WHO International Code of Marketing of Breast-milk Substitutes. Their Assurance Statements are available in the public domain.
Smart thermostat
One issue with using a smart thermostat is the unreliability of the motion sensor. One of the main features of the smart thermostat is the ability to change the temperature when the sensor in the thermostat does not sense an occupant. The only sensor that is used though is the sensor in the thermostat. This means that if the home is occupied but no one walks passed the thermostat, the thermostat will think that the home is unoccupied and will change the temperature, potentially leading to occupant discomfort.
Thermostat
A thermostatic mixing valve uses a wax pellet to control the mixing of hot and cold water. A common application is to permit operation of an electric water heater at a temperature hot enough to kill "Legionella" bacteria (above ), while the output of the valve produces water that is cool enough to not immediately scald ().
Thermostat
A pneumatic thermostat is a thermostat that controls a heating or cooling system via a series of air-filled control tubes. This "control air" system responds to the pressure changes (due to temperature) in the control tube to activate heating or cooling when required. The control air typically is maintained on "mains" at 15-18 psi (although usually operable up to 20 psi). Pneumatic thermostats typically provide output/ branch/ post-restrictor (for single-pipe operation) pressures of 3-15 psi which is piped to the end device (valve/ damper actuator/ pneumatic-electric switch, etc.).
Smart thermostat
Upon installing a smart thermostat, there are additional programs that continue to promote sustainability and reduced energy consumption. The Nest Rush Hour Rewards program partners with utility companies across the United States to incentivize customers to set a higher or lower temperature during peak demand periods. Energy rush hours occur when everyone in a particular area turns on their heating or cooling at the same time, such as during a heat wave. This extra demand may require utility companies to run additional power plants, leading to more cost and carbon emissions. To avoid this, the Rush Hour Rewards program incentivizes customers to set a more efficient temperature that will reduce the amount of energy needed to be produced by the utility.
Smart thermostat
Rather than controlling the temperature of the whole house, zoned systems can control individual rooms. This can increase energy savings, for example by heating or cooling only a Home-office and not the bedrooms and other areas that are empty during the day.
Nest Labs
The Nest Learning Thermostat is an electronic, programmable, and self-learning Wi-Fi-enabled thermostat that optimizes heating and cooling of homes and businesses to conserve energy. It is based on a machine learning algorithm: for the first weeks users have to regulate the thermostat in order to provide the reference data set. Nest can then learn people's schedule, at which temperature they are used to and when. Using built-in sensors and phones' locations it can shift into energy saving mode when it realizes nobody is at home.
