How To Replace Temperature Sensor Battery

The Temperature Sensor takes one Duracell CR-2032 Lithium 3V battery and has a life expectancy of up to 5 years, depending on placement and usage.

To change your Temperature Sensor's battery, remove it from its bracket to expose the battery compartment. Then replace the battery and slide the sensor back into place.

If your sensor is still offline after replacing the battery, skip to the "Is your Temperature Sensor still offline after replacing the battery?" section of this article for troubleshooting steps.
