I have C8 hub with 2.3.9.193 version.
I did the update to .193, 4 days ago and everything was working fine until suddenly last night all non-battery Zigbee devices stopped working.
I tried to remove one repeater and it didn't connect back anymore so I stopped removing devices for now.
I also have tried these things:
- restarting the hub
- disabling Zigbee, shut down, power off and wait for couple minutes, then back on and enable Zigbee
- rebuild network
- reboot radio
- restoring from last backup
- restoring from backup of previous version
Nothing works and I still have the same problem.
My motion sensors and temp sensors are working fine as they are battery powered, but that's it, nothing else works in Zigbee.
