Purifier Card

Air Purifier card for Home Assistant Lovelace UI

By default, the Home Assistant does not provide any card for controlling air purifiers. This card displays the state and allows to control your air purifier.

Installing

💡 Tip: If you like this project ~~and want to get some stickers and postcards~~, consider giving me a tip for the time I spent building this project:

HACS

This card is available in HACS (Home Assistant Community Store).

Just search for Purifier Card in the plugins tab.

Manual

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

2. Put purifier-card.js file into your config/www folder.

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 shortcuts 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: RPM
    subtitle: Motor Speed
  - entity_id: sensor.purifier_filter_life
    value_template: '{{ (value | float(0) / 3600) | round(1) }}'
    unit: hours
    subtitle: Filter Life
shortcuts:
  - name: Silent
    icon: 'mdi:weather-night'
    preset_mode: Silent
  - name: 25%
    icon: 'mdi:circle-slice-2'
    percentage: 25
  - name: 50%
    icon: 'mdi:circle-slice-4'
    percentage: 50
  - name: 75%
    icon: 'mdi:circle-slice-6'
    percentage: 75
  - name: 100%
    icon: 'mdi:circle-slice-8'
    percentage: 100
  - name: Auto
    icon: 'mdi:brightness-auto'
    preset_mode: Auto
show_name: true
show_state: true
show_toolbar: true
compact_view: false

Here is what every option means:

| Name | Type | Default | Description | | ------------------ | :-------: | ------------ | ------------------------------------------------ | | type | string | Required | custom:purifier-card | | entity | string | Required | An entity_id within the fan domain. | | show_name | boolean | true | Show friendly name of the purifier. | | show_state | boolean | true | Show state of the purifier. | | show_preset_mode | boolean | true | Show preset mode of the purifier in the header. | | show_toolbar | boolean | true | Show toolbar with shortcuts. | | compact_view | boolean | false | Compact view without image. | | aqi | object | Optional | Custom entity or attribute for AQI value. | | stats | array | Optional | Custom per state stats for your purifier cleaner | | shortcuts | object | Optional | Custom shortcuts for your purifier cleaner. |

aqi object

| Name | Type | Default | Description | | ----------- | :------: | -------- | --------------------------------------------------- | | 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. |

You can also combine attribute with entity_id to extract an attribute value of specific entity.

stats object

You can use any attribute of purifier or even any entity by entity_id to display by stats section. Not only that, but you can also combine attribute with entity_id to extract an attribute value of specific entity:

| 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. | | value_template | string | Optional | Jinja2 template returning a value. value variable represents the entity_id or attribute state. | | unit | string | Optional | Unit of measure, i.e. hours. | | subtitle | string | Optional | Friendly name of the stat, i.e. Filter. |

shortcuts object

You can define custom scripts for custom actions or add shortcuts for switching presets and percentages via shortcuts option.

| Name | Type | Default | Description | | -------------- | :------: | -------- | ----------------------------------------------------------------------------------------------- | | name | string | Optional | Friendly name of the shortcut, i.e. Switch to Auto. | | icon | string | Optional | Any icon for shortcut button. | | service | string | Optional | A service to call, i.e. script.clean_air. | | target | object | Optional | A HassServiceTarget, to define a target for the current service call. | | service_data | object | Optional | service_data for service call | | percentage | object | Optional | A percentage to switch to, i.e. 27, etc. See entity's percentage_step for valid values. | | preset_mode | object | Optional | A speed to switch to, i.e. Auto, etc |

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

1. It's a service.
2. entity's percentage attribute is equal to shortcut's percentage.
3. entity's preset_mode attribute is equal to shortcut's preset_mode.

Theming

This card can be styled by changing the values of these CSS properties (globally or per-card via [card-mod][card-mod]):

| Variable | Default value | Description | | --------------------------- | ---------------------------------------------------------------- | ------------------------------------ | | --pc-background | var(--ha-card-background, var(--card-background-color, white)) | Background of the card | | --pc-primary-text-color | var(--primary-text-color) | Vacuum name, stats values, etc | | --pc-secondary-text-color | var(--secondary-text-color) | Status, stats units and titles, etc | | --pc-icon-color | var(--secondary-text-color) | Colors of icons | | --pc-slider-path-color | var(--round-slider-path-color) | Color of the slider path | | --pc-slider-bar-color | var(--round-slider-bar-color) | Color of the slider bar | | --pc-toolbar-background | var(--vc-background) | Background of the toolbar | | --pc-toolbar-text-color | var(--secondary-text-color) | Color of the toolbar texts | | --pc-toolbar-icon-color | var(--secondary-text-color) | Color of the toolbar icons | | --pc-divider-color | var(--entities-divider-color, var(--divider-color)) | Color of dividers | | --pc-spacing | 10px | Paddings and margins inside the card |

Styling via theme

Here is an example of customization via theme. Read more in the Frontend documentation.

my-custom-theme:
  pc-background: '#17A8F4'
  pc-spacing: 5px

Styling via card-mod

You can use [card-mod][card-mod] to customize the card on per-card basis, like this:

type: 'custom:purifier-card'
style: |
  ha-card {
    --pc-background: #17A8F4;
    --pc-spacing: 5px;
  }
  ...

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.
