When a sensor loses connection from a Degrii thermostat, it will appear under MAIN MENU > SENSORS on your thermostat and in the app as a hollow sensor with no signal waves and with "N/A" showing underneath.
A sensor could lose connection from your Degrii thermostat if:
- The battery is low.
- It’s too far from your Degrii (more than 17 feet).
- There’s interference from environmental factors (walls, or other devices broadcasting on the same frequency, such as a baby monitor, cordless phone, etc.).
