RGB Light Card

A Home Assistant card for RGB lights

Installation

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

Otherwise, follow these simple steps:

In your home assistant, go to the /config/lovelace/resources page, or from your dashboard, click on the pencil icon > 3 dots > Manage resources
Click on "Add resource"
Set the URL to https://cdn.jsdelivr.net/npm/rgb-light-card and "JavaScript Module" as the resource type
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)

Configuration

The rgb-light-card is meant to be included either:

In the Entities card
As a feature in a Tile card

To start with an example configuration, you can create a new card in your dashboard, then:

Choose "Custom: RGB Light Card" in the card picker
Or choose the Tile card, click on Add feature in the features section, and select RGB Light Card (Tile feature)

Example configuration within an Entities card:

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

    # Card configuration starts here
    - type: 'custom:rgb-light-card'
      entity: light.example_light
      colors:
          # Any option of the light.turn_on action 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

Example configuration as a Tile feature:

# Tile card configuration
type: tile
entity: light.example_light
features:
    # The "feature" configuration starts here
    - type: custom:rgb-light-card-feature
      entity: light.example_light
      colors:
          # Any option of the light.turn_on action 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

Performing Actions

By default, clicking an icon performs the light.turn_on action with the options you defined.

If you want more flexibility, you can use type: action to perform a different action, with optional data in a data object.

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

Example configuration:

type: entities
entities:
    - type: 'custom:rgb-light-card'
      colors:
          # First icon calls a script
          - type: action
            action: script.turn_on
            data:
                entity_id: script.night_mode
            icon_color: '#90b2ec'
          # Second icon calls a scene
          - type: action
            action: scene.turn_on
            data:
                entity_id: scene.romantic
            icon_color: '#f1a5cb'
          # Third icon sends a mobile notification
          - type: action
            action: notify.mobile_app_pixel_8
            data:
                title: Hey
                message: I'm your mobile phone
            icon_color: '#77e28a'

Note that you can mix lights and actions 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

Labels

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:
