ZHA restarts and failing as of 2024.4.3, are there any easy to use alternatives

Configuration Zigbee

I have a SkyConnect v1.0 and use ZHA.
I just upgraded to 2024.4.3 and ZHA is restarting every few hours (because of a watchdog timeout) and then fails to initialize making all zigbee devices unavailable.

So this is pretty serious making my HA unusable now.
Apart from rolling back to the previous version I used (2024.3.3) are there any other alternatives (other coordinators or something) to get zigbee operational again?

But why is this happening? I also have SkyConnect and ZHA, and upgrading has been painless.

You really need to know before you start swapping hardware. Have you been through the diagnostic layers?

  • Power supply (important if you’re running on a Raspberry Pi).
  • Local interference (the USB cable supplied with the SkyConnect is not really long enough).
  • Network interference (has your neighbour changed their wi-fi channel?).

Even if the upgrade is to blame, you need to know why - another integration/coordinator may be just as bad.

Lots of good advice here:

@Stiltjack thanx for the link.
I will go throught it but I’m pretty sure that 2024.4.3 caused this because that was the only change that has occured.
In my logging I see a watchdog timeout (see attached below).
I’m not an expert on this and my HA is pretty much useless now because I need to restart it every few hours.
I have reported the issue already, but ofcourse a fix will take too long.
For me to get the knowledge, will take too long as well, hence my question for an alternative to ZHA.
I guess I will downgrade now and hope this fixes it.
