Update failed – there is no response from the thermostat. The display is blank and no light is illuminating the red ring.
If the update failed, you have to open the thermostat list. Do that by closing the App completely, or simply press the thermostat name in the top of the home screen.
- 'Unknown thermostat’ should appear on the list. Choose ‘Unknown device’
- Press install
- Stay close to the thermostat
