Smart thermostat
In 2011, Nest Labs developed the Nest Learning Thermostat. The Nest Thermostat attempted to reduce home energy consumption by addressing the problems with programmable thermostats through the use of better technology. This new technology included the implementation of sensors, algorithms, machine learning, and cloud computing. These technologies learn the behaviors and preferences of the occupants, and adjust the temperature up or down to make the occupant comfortable when they are home and to save energy when they are away. Additionally, the Nest Thermostat connects to the home Wi-Fi. This allows users to change the temperature, adjust the schedule, and check energy usage from a smartphone or laptop. All of these features were part of Nest's goal to create an easy to use thermostat that saves users energy and money.
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.
