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.
Google Wifi (router)
Google Wifi can be purchased two ways: as a single unit or a multi-pack. One Wifi device is a little white cylinder. When combining multiple devices, it will automatically switch between access points. The router itself supports 802.11ac connectivity with 2.4GHz and 5GHz channels, 2x2 antennas, with support for beamforming. Wifi has two gigabit Ethernet ports, and contains a quad-core processor with 512 MB RAM and 4 GB flash memory. A companion mobile app provides the ability to selectively control Wi-Fi access.
