Google Nest Temperature Sensor (2nd Gen, Single, Porcelain)

Manage hot and cold spots in your home with this 2nd generation Nest Temperature Sensor from Google. When you place a sensor in a room, whether it's mounted to a wall or placed on a shelf, it can communicate with your Nest thermostat via Bluetooth LE to adjust the temperature to your liking. Use the Google Home and Nest apps for setup and management, selecting the temperature you desire and the time you desire it. With additional purchases you can complete the system, as Nest supports up to 6 sensors. With more than one setup, you can prioritize a specific room or average the temperature across all rooms. Once set up, the replaceable CR2 lithium battery will run a single sensor for up to 3 years.
