I have three Fritz! boxes in a mesh network. Two are running firmware 8.0. The primary Fritz!Box for AVM’s Smarthome products for openHAB is still running version 7.56. I have already upgraded the 7590 to version 8 several times with the result that no AVM Think was accessible via openHAB. In the end, the only option so far has been to downgrade to 7.56 so that everything works smoothly again. Even individual DECT 200 sockets to which I have assigned a different Fritz!Box (firmware 8.0) as a bride cannot be switched. If I reassign the socket to the box with the 7.56 firmware, I can switch it again. I have not yet found a solution…
