What should I do if one of my Wiser Radiator Thermostats is no longer connected to the system?

From time to time you may see in the Wiser Home app that either a room is showing no temperature data, or a device is showing no signal. This can happen due to a variety of reasons listed below:

1. Poor signal between the Wiser HubR and the Wiser Radiator Thermostat.
2. The batteries need replacing in the Wiser Radiator Thermostat.
3. The Wiser Radiator Thermostat has been reset through human interaction at the physical device.

Try the following actions to resolve the issue and return your device back into the Wiser network.

Check the batteries, swap out for some new ones (we advice using AA Alkaline batteries only), force close the app, wait 2 minutes, re-open the app and see if the radiator thermostat has re-joined the system.

Or,

Either with new batteries (AA Alkaline) or the existing installed batteries (AA Alkaline), remove the back panel of the radiator thermostat and remove one battery only. Then twist the cap of the radiator stat in either direction to dissipate any remaining charge, then re-insert the battery you had taken out, and replace the back panel of the radiator thermostat. This will force the device to rejoin the Wiser system.

When the radiator stat powers back up, it will have flashing LEDs on the front. To force the calibration, please twist the cap to the minus (-) symbol for 3 seconds and this will re-calibrate the device. Then force close the app, then re-open, and check that the radiator thermostat has re-joined the system.
