I’ve had my HA set up for over a year now with Zigbee2Mqtt working fine on a CC2531 stick.
However in the last couple of months my HA would seem to die for no reason in that i couldn’t access the HA webpage and no automations would work. I also noticed that occasionally my zigbee network would just stop working.
As such i looked at the Zigbee2mqtt logs and had a message about it noting being able to connect to the adaptor.
As such i looked online at found that it might be because the firmware on the CC2531 is becoming corrupt. As such i flashed a new firmware on another CC2531 stick and plugged it in. This seemed to work fine but i noticed that my Zigbee2mqtt version was old (was on 1.18) and from looking at it the respotrity for it had change. As such i added the new version and now have it on 1.23. In this process i lost all my zigbee devices but reconnected them all with no issues and it seemed to be working perfectly again.
However about a day later all my Zigbee devices had stopped working again and when i look in the logs i have the below error messages
Zigbee2MQTT:error 2022-02-27 13:00:34: Error while starting zigbee-herdsman

I did some more research that this might be because of the power draw of the CC2531 so i brought a powered USB hub but still have the same issue.
When i first started having this issue it would only sometimes not work and now it is all the time.
Has anyone got any ideas as I find it odd that it’s been rocksteady for over a year but suddenly i’m having these problems.
I’ve still got the same number of zigbee devices (6 in total) and I can’t think of anything that would have changed to affect it
Everything is working fine. Sometimes I get errors on pinging some light switches but they are working fine. I don’t know why this error is showing. It might have something to do with sonoff smart plugs but i’m not sure.
Anyway try to use just usb port.
