Same for me - after last update to 2024.2.4 and deconz software my conbee and zigbee are offline. Under 2.4 i got i working after couple of restarts. Did to 2024.2.5 today - trying everything - it is not working anymore - even with unplug or restarts. Is there any rock solid zigbee solution for hA ? different stick / zigbee2mqtt?

If the Conbee is physically missing, there is nothing that can be done. ZHA expects the serial port to exist. If your VM or hypervisor has issues with the Conbee and USB passthrough, you will need to find a workaround, as it's a layer above HA OS.

I thought maybe my Conbee 2 stick is broken - so I bought Conbee 3. There were some troubles with the change from 2 to 3 in HA, so I decided to link all devices again with the system. Right now it is working w/o problems, I will update this post if the next update is avialable & system restart was initiated

[puddly]

The Conbee 2 is a little strange in that it manages its own USB interface and also fully resets (i.e. "unplugs" itself USB-wise) if nothing communicates with it for 30s. If your hypervisor has issues with hot plugging USB, you'll have problems with it.

Maybe try this (Solution form Jesper) https://community.home-assistant.io/t/zha-conbee-2-not-working-after-update-2024-2-5/697336

It did work for me - but i really had to remove the conbee 2 - and shutdown the pi - disconnect energy- start up again - connect conbee 2 - reconfigure and it was working again. All the restarts before - also of the pi did not solve the problem.

60% of my Zigbees are back - aqara door sensors and temperture sensors are still offline. Will try skyconnect now.

currently the ConBee 3 stick is running w/o any issues... Maybe @puddly is right and my Synology VM has the problem with the 30s communication...?
