How To Replace Temperature Sensor Battery

The Temperature Sensor takes a single 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 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 section below for troubleshooting steps.
