Same issue here with latest version of HA 2023.3.5 and newest compact unit.

[iPoiizz]

Same, when added the 4 compact to HA (2023.3.5), it disconnected to the network and try to reconnected, while remove from HA it works fine.

[peca89]

Just found out that the connection is successful if you select Cloud during adding the integration instead of Automatic...

Just found out that the connection is successful if you select Cloud during adding the integration instead of Automatic...

Just did this and had the same experience. I thought the goal of this was to go local and not require cloud?

[al-one]

Try master branch.

[peca89]

Adding via automatic option still does not work for me. Also, I don't see that newly added Reset filter life does anything.

[al-one]

Try add custom option chunk_properties: 1 for zhimi.airp.cpa4.

xiaomi-mito-customize.mp4

[peca89]

Adding via both Automatic and Local works fine with 'chunk_properties: 1'. Thanks.

Also works fine when adding that option to device_customizes.py

Reset filter life still does not reset Filter Used Time to 0 if that is what it is supposed to do

[pyrodex]

Try master branch.

I was able to pull MASTER down via HACS and then restarted. I removed the prior setup I had for my CPA4 and was able to add it in as Local without issues. Thanks!

[al-one]

Try master branch again.

Anyone who wants to control the cpa4 via the mushroom fan card check out what I did:

Feel free to make PR and issues 😃

Best and greetings from Switzerland

Just added the device, working great, only missing control on Home Assistant seems to be changing from Manual to Auto to Sleep mode?

[KSchmeeds]

I recently purchased the zhimi.airp.cpa4 and I've noticed using local or automatic the device entities keep going unavailable and then coming back.

If I use cloud option, I'm unable to change the modes from auto,sleep,favorite. The option to change it is there, but it doesn't take affect and keeps flipping back.
