A Lovelace custom card for RGB lights

Light Dark


If you have HACS, you can install the RGB Light Card from there and jump to the "Configuration" step

Otherwise, follow these simple steps:

  1. In your home assistant, go to the /config/lovelace/resources page, or navigate to Configuration > Lovelace Dashboards > Resources tab

  2. Click the + button

  3. Set the URL to https://cdn.jsdelivr.net/npm/rgb-light-card and keep "JavaScript Module" as the resource type

  4. Click "Create"

Note: The RGB Light Card will upgrade automatically a few days after every new release (once your browser cache expires)

However, you can enforce a specific version by adding @X.X.X at the end of the URL (e.g: https://[...]/rgb-light-card@1.8.0)


The rgb-light-card is meant to be included in the Lovelace Entities Card

You can start with a sample configuration by choosing "Custom: RGB Light Card" in the Lovelace card picker

Example configuration:

type: entities
show_header_toggle: false
    # Displays the light entity. It's optional
    - entity: light.example_light

    # Card configuration starts here
    - type: 'custom:rgb-light-card'
      entity: light.example_light
          # Any option of the light.turn_on service can be used in each color
          - rgb_color:
                - 255
                - 127
                - 255
            brightness: 220
            transition: 1
          - hs_color:
                - 60
                - 30
            icon_color: '#fff8b0' # Override icon color

You can test all the colors options in the Developer Tools > Service page of your Home Assistant.

Choose the light.turn_on service, change the service data, and call the service to see the result

Calling Services

By default, clicking an icon calls the light.turn_on service with the options you defined.

If you want more flexibility, you can use type: call-service to call a different service, with the data you want.

You can find more information about service in the Home Assistant documentation

Example configuration:

type: entities
    - type: 'custom:rgb-light-card'
          # First icon calls a script
          - type: call-service
            service: script.turn_on
                entity_id: script.night_mode
            icon_color: '#90b2ec'
          # Second icon calls a scene
          - type: call-service
            service: scene.turn_on
                entity_id: scene.romantic
            icon_color: '#f1a5cb'
          # Third icon sends an Alexa TTS notification
          - type: call-service
            service: notify.alexa_media_office
                    type: tts
                message: Hello world!
            icon_color: '#77e28a'

Note that you can mix lights and service calls in the same card

The icon_color is still optional, but will be grey by default

Customization examples

Icon color

The icon_color option accepts the same values as the CSS background property.

This means your icon_color can be:

  • A HTML color name:   icon_color: gold
  • A hexadecimal code:   icon_color: '#FBB48C'
  • Any other color compatible with background-color:   icon_color: rgba(42, 204, 77, 0.5)
  • A color gradient:   icon_color: 'linear-gradient(15deg, #0250c5, #d43f8d)'
  • Or even an image:   icon_color: center/120% url('https://www.home-assistant.io/images/favicon-192x192.png')

The 5 examples above will render like this:

⚠️ You must wrap your value between quotes if it contains the # character

Material design icons

As explained above, the icon_color option accepts any valid CSS value

If you want icons in your colors, you can use the icon tool to convert material design icons into CSS

Small labels can be added below color icons, using the label option of each color. Their size can be customized with the label_size option (default to 12 pixels).

Labels can be just a text, but also accept HTML, which means you can be really creative:

  • Simple text: label: Red
  • Bold text: label: <b>Orange</b>
  • Or more complex HTML: label: '<span style="color: #609fc6">Blue</span>'

There are 5 possible values for the justify option: left,right,center,between and around. The default value is left.

Here are how the different values are handled:
