For Geofencing to work properly, we recommend that you remove any mobile devices that are no longer in use from your account.
To remove a mobile device, please do the following:
Open the tado° app.
Go to More > Account > Mobile devices.
Select the device you want to remove.
Select Remove device.
When the confirmation message appears, select Remove to confirm.
After you remove the device, tado° will no longer display it on your Geofencing screen or use its location for Geofencing.
Note: You can remove only your own devices, regardless of whether you are an Admin or a regular user.
