Purifier Card

Air Purifier card for Home Assistant Lovelace UI

Manual

1. Download purifier-card.js file from the latest-release.

3. Add a reference to purifier-card.js in Lovelace. There's two way to do that:
   1. Using UI: Configuration → Lovelace Dashboards → Resources → Click Plus button → Set Url as /local/purifier-card.js → Set Resource type as JavaScript Module.
   2. Using YAML: Add the following code to lovelace section.

      resources:
        - url: /local/purifier-card.js
          type: module

4. Add custom:purifier-card to Lovelace UI as any other card (using either editor or YAML configuration).

Using the card

This card can be configured using Lovelace UI editor.

1. In Lovelace UI, click 3 dots in top left corner.
2. Click Configure UI.
3. Click Plus button to add a new card.
4. Find Custom: Purifier Card in the list.
5. Choose entity.
6. Now you should see the preview of the card!

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

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

type: 'custom:purifier-card'
entity: fan.purifier
stats:
  - attribute: filter_life_remaining
    unit: '%'
    subtitle: Filter Remaining
  - attribute: motor_speed
    unit: RPS
    subtitle: Motor Speed
actions:
  - name: Silent
    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

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

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.

Animations

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 remove.bg.
6. Then I upscaled each of those images using icons8.com/upscaler.
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.

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.
