Hey everyone,
Last night, I migrated my entire Zigbee network from ZHA to Zigbee2MQTT, and I’m still a bit new to this whole setup. I’ve reconfigured all my automations, and everything seems to be working fine – except for my hallway light.
When I switched over, I removed the light switches to put the Sonoff ZBMiniL2 into pairing mode. It was detected by Zigbee2MQTT, but I still can’t control it. I keep getting this error (see screenshot). It worked perfectly fine under ZHA, and my bathroom light with the same module is working without any issues.
Does anyone know how to fix this without having to remove the switch again? 
Second question:
When trying to update devices via OTA, I constantly get the error Route_Error_Many_To_One_route_Failure for “39996” or some other ID. Is this normal, or is there a way to fix it?
Third question:
I noticed that some devices seem to be „floating“ in the network or not properly connecting to a router. Is this expected behavior, or did I mess something up? If so, how can I fix it? 
Thanks a lot for your help!
