It’s the only plug I have but I have no idea where to start looking. Should I restore the backup from yesterday?
I’ve attached a screenshot.
Home Assistant 2022.9.4
Supervisor 2022.08.6
Operating System 9.0
Frontend 20220907.2 - latest
Yes it is something strange here. I have Zigbee plugs also but after upgrade to OS 9.0 they have started to behave strange in ZHA. Can operate them via UI (sometimes) but their state in not updating as they were.
I restored the backup but unfortunately the OS is not restored and the problem remains
ha os update --version 8.5
did the trick in the Terminal
It seems like the update is now pulled. Hopefully they find the issue that this is linked to
Pulling the update explains what I saw then. I thought I was losing it. I restored a day old backup and things were fixed. Then I saw an update so I tried it again figuring I could restore the backup again. This time it updated and all was well…so far.
Going forward I think I’ll wait a day or two before I update anything.
It fried one off my plugs (Neo Coolcam). Could not factory reset it and not re-include it. Luckily (well not really) 
I had some new lying around and all is back to normal. I knew it so well, to wait, but pressed the update switch anyway …
