@Danielteuschl Would it be possible to factory reset and re-adopt each device in turn and re-adopt to see if that resolves the issue? Also, were there any firmware updates around the time the issue...

@Danielteuschl Are the devices experiencing the error only wired/only wireless, or a mix? When did this issue start happening (maybe after a firmware update on a device)? Is it across your network or...

@djwujek The beta version will be your issue here. You'll need to downgrade to a release version first, and then to the patched version. Another user had the same issue with a different model here:...

@GlenO You should be able to factory reset via the physical button on the devices.

@djwujek What is your current firmware version? Can you send a screenshot of the error code you're getting?
