Thermostat or Remote Temperature Sensor Showing N/A – Troubleshooting Steps

If your thermostat or Remote Temperature Sensor (RTS) is displaying N/A instead of a temperature, it usually means the device has not yet reported temperature data to Alarm.com after installation.

When a Thermostat Displays “N/A”

This issue commonly occurs immediately after installation when the thermostat has not yet communicated with the Z-Wave network.

To Resolve the Behavior:

1. Turn the thermostat on.
2. Adjust the temperature setting by a few degrees.
3. Wait a few moments—temperature data should begin reporting shortly after the manual change.
4. If the thermostat still shows N/A after a few minutes, remove and re-enroll it in the Z-Wave network.

When a Remote Temperature Sensor (RTS) Displays “N/A”

An RTS can also display N/A for the same reason—lack of temperature reporting after initial setup.

To Resolve the Behavior:

1. Manually adjust the temperature reading by changing the environment near the RTS by one degree (e.g., briefly warm or cool the area).
2. Wait a few minutes to allow the RTS to report its updated temperature.
3. If the issue persists, press the button on the side of the RTS to prompt communication.
