@joostlek didn't we try to fix this?

[joostlek]

Nope

[OhioSpyderman]

Add me to the list getting this error.... :(

PS - Thanks for fixing the PS4 one...

Bob.

[fredrike]

@OhioSpyderman do you have a issue number for the ps4 issue so I van take some insperation.

Bob.

EDIT: FWIW, the event loop in this/my case (with the new issue) is AMCREST

Detected blocking call to load_default_certs with args

Just got this with the latest core update...

Trying to help...

Bob.

[davidmtml]

Also experiencing this with the AmCrest integration.

[tomlut]

You will need to open a seperate issue for that.

Has there been any progress with this issue recently @fredrike?

[fredrike]

I can try to get a fix out for this.

[redlefloh]

Just confirming, that I also get this with the Harmony integration (running HA Core 2025.1.2).

Thanks so much for looking at it @fredrike!

[tomlut]

That is unrelated to this issue which is specifically about the Daikin integration. You need to open a seperate issue for the harmony remote integration as it says to do at the end of that report.

[gomesp]

Hi team, I just found this thread and have the same issue but running HA core 2024.12.5. Is there a downgrade path that resolves the issue until a fix is available please?

[tomlut]

amcrest/init.py

Again. Not related to this issue which is for the Daikin integration. Delete your post and open a new issue for the Amcrest integration.

[tomlut]

Thanks Fredrike, confirmed as fixed in 2025.4.1.

[OhioSpyderman]

Installed 2025.4.1 this morning. The problem still persists.

Bob.

[tomlut]

That is not caused by the Daikin integration. It is the Amcrest integration. Completely different issue.

[genehand]

Anyone having trouble with amcrest, try the Dahua integration instead: https://github.com/rroller/dahua. It supports several additional sensors and controls as well.
