Help!

When I restart my Home Assistant after the last update (core 5.4) my ZHA integration won’t start and/or the coordinator won’t start. I’m not sure what is happening, can somebody maybe explain?

I’m sorry if this is maybe not the right log. I know my way around a computer and hardware is my speciality. But when it comes to software, code and troubleshooting by logs, I’m still a newbee and trying to learn what I can.

The code in ZHA is listening to a serial device and doesn’t recognise what it is hearing.

The simplest fix might be as simple as unplug, and re-plug the Zigbee USB coordinator stick to force HASSOS to rediscover it, and create the device file which ZHA then connects to.

If that fails, the next step would be to go into ZHA and look for the Serial device path - effectively the serial port it is using.

Rule of thumb - if there are two similar entries, use the longer one (as less likely to change on a reboot), BUT other stuff like serial consoles, other USB devices, etc can also show up as serial devices.

I read on Github that more people have the issue since the last release. I’m trying to downgrade HASS to a version that worked for me. I’ve already downgraded to HASS 2023.5.2 instead of 5.4 but the OS remains on 10.2. How can I downgrade the OS to let’s say 10.0 or 10.1 since those versions worked for me?
