Experienced the same with my setup after upgrading to 2026.01. Same No Route error. Sonoff 3.0 Stick running on proxmox environment. Tried reboot, unplugging the stick. Restart HA of course. But even switching back to VM Backup didnāt work.
Using ZHA. Donāt know if itās really update related, maybe just restart after update related, because I had some similar issue before but devices where marked as offline. This time itās the no route error.
Zigbee stick is working, because If I repair devices, itās working again. But I donāt want to repair all of my devices. Because some of them are not easy accessible.
okay. Very weird. Restored vm back to last stable. Devices not working. Repaired one of the devices. Device working. Update to 2026.1.0. Device stopped working again. Same issue āStatus.NWK_NO_ROUTE: 205ā
Working again. What helped was to start the Zigbee channel change via the Zigbee network settings.
Picked channel 15. But settings still show me channel 11 and āsmartā if I open up the channel settings again.
So Iām concerned that it will happen again after an update/restart.
Any advices on this kind of failure?
To close this topic for myself. Realised the firmware of my Sonoff 3.0 Zigbee USB stick was pretty old.
Did an pretty easy update through this nice little Addon:
After that the āchange channelā feature works and seems to change the zigbee channel as expected.
Update from 2026.1.0. to 2026.1.1. worked without loosing Zigbee connections now.
