Smart thermostat shows E20 and geofencing or location-based control does not work.

Safety first: No hardware risk; this is an app configuration issue.

• Enable location services: On your smartphone, ensure location services are turned on globally and for the Tado app specifically.
• Allow background access: Set the Tado app’s location permission to "Always" or the recommended setting for geofencing.
• Check user presence: In the Tado app, verify that all household members’ phones are correctly added and that their location permissions are active.
• Test movement: Move a few hundred meters away from home and check if the app updates your status to "Away" and adjusts heating accordingly.
• Re-login: Log out and back into the Tado app to refresh account and geofencing settings.
