Hello,
I just wanted to pair a new device, but something went wrong.
The device itself shows that it’s connected, but Zigbee2MQTT doesn’t show anything about the device.
I also tried to pair a device I’m sure it must work (I have more of it in my Zigbee Network), but it doesn’t work either anymore.
In the logs I also find nothing.
All devices that I’ve paired already work as usual.
Raspberry Pi 4
Conbee 3
I hope anyone could help.
Thank you!
Have you done a full host reboot?
Yes, I completely disconnected the Raspberry from the power supply.
Something in the logs whenever you try to pair a new device? What coordinator are you using?
There is nothing in the logs, this is really strange.
It seems that the devices connect to the Conbee 3 Coordinator, but not no Z2M.
Remove those devices from the Conbee, restart it and then unplug it from your RPI. Thereafter try again to pair the new device(s) to Z2M.
Sadly, this didn’t solve the issue. 
Just switched to ZHA and everything works well.
