The xiaomi_miio fan platform does not work with Xiaomi Air Purifier 3

[ehn]

The problem

I have three air purifiers from Xiaomi: one Air Purifier 2 (mini) (zhimi.airpurifier.m1) and two Air Purifier 3 (2019) (zhimi.airpurifier.ma4). All are connected to my home Wi-Fi and accessible in the Mi Home mobile app through the mainland China cloud.

I'm trying to bring them into Home Assistant using the xiaomi_miio fan platform. I have extracted tokens for all three devices from the iOS app following this guide:

https://www.home-assistant.io/integrations/vacuum.xiaomi_miio/#retrieving-the-access-token

The Air Purifier 2 (mini) (zhimi.airpurifier.m1) works, but the Air Purifier 3 (2019) (zhimi.airpurifier.ma4) don't.

From my config.yaml:

  - platform: xiaomi_miio
    host: 192.168.2.200 # Living room
    token: a743...
    model: zhimi.airpurifier.ma4

I have tried setting the model to zhimi.airpurifier.mb3 as well as removing the line entirely. Neither helps.

Attached a debug-lecel log filtered by "miio".

Environment

Hey there @rytilahti, @syssi, mind taking a look at this issue as its been labeled with a integration (xiaomi_miio) you are listed as a codeowner for? Thanks!

Might be related to #36972 and #36993 as well.

[ehn]

This seems to be caused by this issue: rytilahti/python-miio#730

[rytilahti]

This looks more like an invalid token than other of those linked issues as the device is responding to the handshake but is not responding anything to the queries. So the linked upstream issue is also not relevant.

[ehn]

@rytilahti The tokens were extracted from the iOS app following this guide:

https://www.home-assistant.io/integrations/vacuum.xiaomi_miio/#retrieving-the-access-token

It works for the Air Purifier 2 (mini) (zhimi.airpurifier.m1) but not for the Air Purifier 3 (2019) (zhimi.airpurifier.ma4).

[ehn]

rytilahti/python-miio#745 fixes this issue.

@ehn How did you solve this issue?
I'm facing the same problem with my Mi Air Purifier 3H:
ERROR message:

The xiaomi_miio platform for the fan integration does not support platform setup. Please remove it from your config.

My HASS Container version is: core-2022.4.7

[ehn]

IIRC, it worked after the above-mentioned PR was merged.
