Xiaomi Air Purifier 3C custom support

Describe the bug Since the Xiaomi Air Purifier 3C doesn’t have native support, I am trying to add it manually. I have all the information in the card from custom attributes, but there is no option to control the device with custom entities/attributes. From what I could find, this card is design to work with fan entities and not climate entities and that’s the reason why it doesn’t work.

Is there a way to control this device manually, or do I have to wait for native support?

I am using the following code: `type: custom:purifier-card entity: climate.air_purifier_air_purifier aqi: attribute: environment.pm2_5_density unit: null stats:

• attribute: filter.filter_life_level unit: ‘%’ subtitle: Filter Remaining
• attribute: custom_service.moto_speed_rpm unit: RPM subtitle: Motor Speed actions:
• name: Sleep icon: mdi:weather-night speed: Sleep
• name: Auto icon: mdi:brightness-auto speed: Auto show_name: true show_state: true show_toolbar: true compact_view: true`

Steps to reproduce If you click the on/off, auto, sleep, etc. you get a spinning wheel like in the screenshot above.

Expected behavior Turning the device on/off.

This is my configuration. Works, but currently is not showing AQI value.

fan_set_favorite_level is removed in the latest version of purifier-card. Hopefully this issue is resolved.
