Google Nest Temperature Sensor
With the Nest Temperature Sensor, you can control your home's temperature room by room. Place the sensor on a wall or shelf, pair it with your Nest thermostat (sold separately), and get the right temperature–exactly where you want it.
Note: The Nest Temperature Sensor only pairs with compatible Nest thermostats, which we also sell! Check out the Nest Thermostat E and third-generation Nest Learning Thermostat.
