Zigbee2mqtt: Stops working, only way to fix is unplug/plug cc2531 and restart service - on hassio/proxmox

[stevetz]

What happened/expect/reproduce

Zigbee devices stop responding in home assistant after a period of time. Z2M was running solidly for 3 months, with no disconnects or any issues as far as I could tell. I moved house a month ago, but otherwise no problems when reinstalling all the devices here. This issue first occured two weeks ago (3 weeks after moving - where everything was fine), so I'm not sure the issue is the fault of the changed physical network layout etc...but it could be?

In order to fix this, I must unplug and replug the CC2531 stick and restart the service (through home assistant frontend, restart the addon). As far as I can tell the device is showing as connected to the proxmox node, and the green LED remains lit.

The issue repeats every 24-36 hours, I haven't yet figured out if its a regular pattern

I've enabled debug logging, here is a section of the most recent log: https://pastebin.com/UTU4pucK. I'm not sure if it helps?

In troubleshooting, theres quite a few things that could be the cause: I hope I can eliminate z2m first, then the addon, then hasso, then proxmox... Maybe a reflash of the stick at some point - though I did it through a Pi which ive since repurposed, so the effort of flashing an OS sent me here in the first instance. Thank you!!

Known issue, should be fixed by updating to the latest dev branch (https://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html), duplicate of https://github.com/Koenkk/zigbee2mqtt/issues/4307

Sorry I didn't find the other issue, must have failed my searching class!

This has also spurred me on to (finally) give a small paypal gift. Thank you for all you do @Koenkk !

No problem, please let me know if after upgrading the issue is solved.

[stevetz]

I'll report back in a couple of days if there have been no further crashes.

So far so good... I've not experienced any crashes or errors since switching to the dev branch - at 9am GMT on 19th - so 73 hours of uptime! (via the home assistant z2m edge).
Thanks!
