ZHA Broken in 2023.6?

Configuration Zigbee
1

ZHA no longer loads and i see the following error in the logs:

From my reading it looks like coroutine was removed from asyncio in Python 3.11.

As you might imagine, ZHA being broken would have made quite a fuss :wink:

That one seems specific to your setup, of which we know nothing.

3

Yep, which is why I was confused why I could not find anything in the forums. My system is pretty vanilla using HassOS:

Home Assistant 2023.6.3
Supervisor 2023.06.2
Operating System 10.3
Frontend 20230608.0 - latest

Running on raspberry pi 4 (ssd).

My zigbee stick is the HUSBZB-1.

According to this SO post coroutine was removed from asyncio in 3.11 (which I know 2023.6 upgraded to):

I assume some dependency needs to be updated, but I wasn’t sure how to.

You wouldn’t have a custom integration with an old dependency on pyserial-asyncio, would you (<0.4)?
There you can find those coroutine decorators, but not in the 0.6 that HA itself downloads.

Yep that was it. I had an old custom integration that I hadn’t updated in a while. Thanks for pointing me in the correct direction.

It seems I have the same problem. Is there somewhere a guide to migrate away from the pyserial-syncio? I can’t find it.

[edit]I figured it out.
Using replacing import serial_asyncio with import serial_asyncio_fast as serial_asyncio seems to do the trick for fixing the custom integration.[/edit]

[edit2]The problem with ZHA remains. How do I get rid of the deprecated pyserial-syncio so it doesn’t cause a conflict anymore?[/edit2]

I had missed the dependency declaration in the manifest.json of the custom component.

So the solution consists of:

  • Using replacing import serial_asyncio with import serial_asyncio_fast as serial_asyncio seems to do the trick for fixing the custom integration.
  • Replacing pyserial_asyncio==0.4 by pyserial_asyncio_fast==0.13 in manifest.json of the custom component (versions may vary depending on the plugin)
  • Restart the Home Assistant docker container to pull in the right dependencies and to leave out the deprecated one.
