Zigbee devices no longer communicating

[boasist]

The problem

About 11:50am on July 8, some of my zigbee lights started flashing without any user input, this went on for about five minutes before I went to the dashboard and turned them off. The flashing happened again shortly after, and now since then they are showing completely offline and I cannot communicate to them. Power outlet is operating normally, other zigbee devices flickered as well, yet are operating as usual.

While these are hue lights, I have them all configured directly through zigbee, and not a hue bridge.

I've tried to reconfigure them with no change, as it fails on communication.

Attached is the debug log where I attempted to reconfigure two of the offline units, and then issued commands with the hue remote to turn them on. home-assistant_zha_2024-07-09T13-15-10.838Z.log

Same problem

[puddly]

Have you tried power cycling the lights? Off for five seconds, then back on? The firmware in some is known to crash.

[kittyscastle]

@puddly I searched the known issues, because of ZHA issues that started with 2024.7.x, and saw the same remark about ‘power cycling’ a couple of times.

first I suspected the ‘database foreign …’ to be the cause, tried again when I saw the included fix in 7.2 but running into the same issues of ZHA not passing initialisation.

Quickest stable (so far) fix: regression to a 2024.6.x backup. Restarting after that and immediately starting to see the sensors and lights coming back to report.

I do not pretend to know the code and structure of ZHA, but could the two be related: the fix for the database causing ZHA to run into it’s own trouble? (maybe just for old database and early ZHA adopters)

PS two tries of going forward and backwards a core version with same results & prior ‘years’ of stable ZHA-zigbee network & immediate reporting from the ‘external’ coordinator which did not restart zigbee since it’s external via IP socket. (The old sonoff wifi coordinator)

@kittyscastle Can you include a ZHA debug log and open a separate issue? If you're having issues with startup, it won't be the same root cause as this issue.
