How to fix "custom integration 'brematic' calls async_write_ha_state"

Development

Hi there,

I use a fairly old (and small) integration, which worked well so far. But with the current beta 2024.5, I can’t use it anymore and get this error:

Detected that custom integration 'brematic' calls async_write_ha_state from a thread at custom_components/brematic/switch.py, line 242: self.async_write_ha_state().

These are the lines, that are causing this issue: hass-brematic/custom_components/brematic/switch.py at 4e76898b638528d5058d02f986aafcb39189a012 · tefinger/hass-brematic · GitHub

I’m quite certain that the author will not respond to this quickly (if ever). Is it easy to fix this issue manually? Would really appreciate some help.

Thanks!

I think it’s just updating the async_write_ha_state() to schedule_update_ha_state() since it’s not in an async function.

Yes that’s it! Thanks you very much. Worked without issues

It’s likely not a thread safe application, which recently (2024.4.x) is causing HA to crash after the full conversion to python 3.12.
You should check it with this process: Discord.
It is in the general channel of the HA Discord and will tell you if this is integration is writing unsafe thread writes.
If you can’t get to it let me know.
