Meet the Google Nest Temperature Sensor. It communicates the temperature to compatible Google Nest thermostats, like the Nest Learning Thermostat (3rd Gen) and the Nest Thermostat E. You can put different Nest sensors in different rooms, and then use the Nest app to choose the exact temperature you want the room to be, along with the time of day. And it’s simple to install yourself – just hang it on the wall or place it on a shelf. The Nest Temperature Sensor requires a 3rd generation Google Nest Learning Thermostat or a Google Nest Thermostat E. Identify your thermostat at nest.com/which thermostat. Remote control and mobile notifications require working internet and Wi-Fi.

How does it work?

Your sensor will tell your Nest thermostat the temperature in the room where it’s placed. Your thermostat will use that reading, rather than its own built-in sensors, to control when the system turns on or off. You can schedule it to use different sensors at different times of the day.
