Zigbee coordinator unavailable after update - Not responding to resets

Configuration Zigbee
1

Hi guys. I updated HA on my RPi4B last night to latest build and everything went well except the Zigbee coordinator (Sonoff +) stopped working and seems to be reporting ‘unknown’ and ‘unavailable’ for it’s device info. Tried a HA shutdown then power cycle on the Rpi and when that failed tried replugging the stick etc. Didn’t help.
I can’t see any breaking changes to do with ZHA in the release, did I miss something in the recent updates ?

Home Assistant 2023.1.7
Supervisor 2023.01.1
Operating System 9.5
Frontend 20230110.0 - latest

They did a lot of wifi and blue tooth work in the last update. Did you not read the release notes before upgrading?

I always skim the notes. Have I missed something relating to Zigbee coordinators ?

reinstall zigbbe coordinator. the issue can fix it

Thanks, I did that (before reading here) and it did work. All my devices got unpaired though. Still trying to re-pair some. Zigbee can be a real PITA, I hope Matter is more solid like my BLE and RF sensors are.

I also have been having the issue, after each recent update I have to repair the zigbee components dConz and the Conbee II Zigbee automation integration. Which I noticed with Operating System 9.5 and Home Assistant 2023.1.7 update started to fail.

I was able to get it all working again, then 2023.2 came and it all broke again. Again having to remove USB device put it back in, restart dconz several times until I could reload the integration to get it started again.

It was never this flaky before. I’m working again, but for how long? The stability does not seem to be there anymore, not sure if something to do with the rework or some other underlying issue.

Guess we aren’t the only ones: Github issue

Thanks for posting that Github issue link. Yes my experience mirrors theirs with devices and the coordinator going unavailable after last update.
I dicked around with deleting the ZHA integration and reinstalling it and pairing quite a lot till I was out of time to spare, as most would not reconnect even when the coordinator finally did. Decommissioned my ZHA network until the next update of OS and HA, then I’ll test again.

I’ve got the Sonoff 3.0+ and ZHA behaving again. I did two things, waited for the next HA core update and installed it, and then also found a recent ZB stick firmware update and installed it (by this method).
One or the other step has helped, HA detected the stick and sensors easily again like it should be doing.

Here we go again with my ZHA going off-air and then MIA when trying to repair whatever the issue is now.

Oh Zigbee, if only I could go back in time and avoid you in the first place…

Some four months later and some positive things to say about Zigbee on HA.
Finally I have got a stable Zigbee network and finding that also fixed numerous other issues like some devices eating batteries like candy.
The fix for me (so far touch wood so to speak) was when HA ZHA updates got the ability to set the USB coordinator radio channel. When I saw this new feature I was able to set the Zigbee channel away from my home WiFi channel (which had to stay where it was to avoid neighbor clashes). That made a major difference to device availability. Well done HA dev’s.
Since that progress I was prepared to buy a couple more devices including an IKEA Tradfri USB repeater. That was a good purchase, the reliability of devices like buttons at the far end of the house is now close to 100%.
