Sorry, no support for actions and stats in visual config yet.

Typical example of using this card in YAML config would look like this:

    unit: '%'
    subtitle: Filter Remaining
  - attribute: motor_speed
    unit: RPS

    icon: 'mdi:weather-night'
    speed: Silent
  - name: 25%
    icon: 'mdi:circle-slice-2'
    speed: Favorite
    xiaomi_miio_favorite_level: 3
  - name: 50%
    icon: 'mdi:circle-slice-4'
    speed: Favorite
    xiaomi_miio_favorite_level: 7
  - name: 75%
    icon: 'mdi:circle-slice-6'
    speed: Favorite
    xiaomi_miio_favorite_level: 10
  - name: 100%
    icon: 'mdi:circle-slice-8'
    speed: Favorite
    xiaomi_miio_favorite_level: 14
  - name: Auto
    icon: 'mdi:brightness-auto'
    speed: Auto
show_name: true

Here is what every option means:

entity_id string Optional An entity_id with state, i.e. sensor.current_aqi.
attribute string Optional An attribute which should be used to get AQI value.
unit string Optional An unit of measurement to display.

stats object

You can use any attribute of purifier or even any entity by entity_id to display by stats section:

Name Type Default Description
entity_id string Optional An entity_id with state, i.e. sensor.purifier_aqi.
attribute string Optional Attribute name of the stat, i.e. filter_left.
unit string Optional Unit of measure, i.e. hours.

actions object

You can define custom scripts for custom actions or add shortcuts for switching modes and speeds via actions option.

The card will automatically try to figure out which one of actions is currently active. The action will be highlighted when:

  1. It’s a service.
  2. entity‘s speed attribute is equal to action‘s speed.
  3. entity‘s speed attribute and favorite_level is equal to action‘s speed and xiaomi_miio_favorite_level correspondingly.


I’ve added an animation for this card to make it alive:

How did I make this animation? It’s a long story…

  1. I took original gif file from here.
  2. Then I tweaked image levels to make the background black and purifier white.
  3. Then I inverted colors on the gif.
  4. Then I’ve split the gif by frame.
  5. Then I removed the background of the image frame by frame using
  6. Then I upscaled each of those images using
  7. Then I put up all of those images back in a single gif.
  8. Profit!

Archive with images from all of these steps can be found here.

Supported models

This card relies on basic fan services, like toggle, turn_on, turn_off, etc. It should work with any air purifier, however I can physically test it only with my own purifier.

If this card works with your air purifier, please open a PR and your model to the list.
