Google Nest Temperature Sensor 2nd Gen

No, the sensor does not control your HVAC system directly. It communicates temperature data to your compatible Nest Thermostat, which then adjusts your heating or cooling based on the temperature in that specific room rather than just the hallway where the thermostat is located.

The sensor is compatible with most Nest Learning Thermostats and the Nest Thermostat E. It is not compatible with the 1st generation Nest Learning Thermostat or the Nest Thermostat (2020 model) that lacks remote sensor support.

You can connect up to six Nest Temperature Sensors to a single Nest Thermostat, and up to 10 sensors total across your entire home if you have multiple thermostats.

Installation is straightforward and requires no wiring. You can either mount the sensor on a wall using the included screw or simply place it on a shelf or flat surface.

The sensor is powered by a single AAA lithium battery, which typically lasts up to two years. The Nest app will notify you when the battery level is low so you can replace it.

Yes, once connected, you can ask Google Assistant to tell you the temperature in specific rooms where you have placed a sensor.
