> A Home Assistant card for RGB lights

## Installation

If you have [HACS](https://hacs.xyz/), 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 from your dashboard, click on the pencil icon > 3 dots > Manage resources

2. Click on "Add resource"

3. Set the URL to `https://cdn.jsdelivr.net/npm/rgb-light-card` and "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](https://github.com/bokub/rgb-light-card/releases) 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](https://www.home-assistant.io/dashboards/entities/)
-   As a feature in a [Tile card](https://www.home-assistant.io/dashboards/tile/)

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:

```yaml
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:

```yaml
# 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
```

> #### Pro tip
>
> You can test all the colors options in the **Developer Tools > Actions** page of your Home Assistant.
>
> Choose the `light.turn_on` action, edit the options (or the `data` in YAML mode), and click "Perform Action" to see the result

### Colors options

| Name | Type | Requirement | Default | Description |
| ---------------------------------------------------------- | ------ | ------------ | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `rgb_color`, `hs_color`, `brightness`, `transition` etc... | any | **Optional** | | When you click on a color, it will perform the action `light.turn_on` with **all the options you put here** as action data [**Click here**](https://www.home-assistant.io/integrations/light#action-lightturn_on) for the full list of options |

| `type` | string | **Optional** | `light` | Can be set to `light` (default), or `action` to change the click action. Read the [explanation](#performing-actions) just below |
| `action` | string | **Optional** | | Used with the `action` type to specify the action to perform when clicked |
| `data` | array | **Optional** | | Used with the `action` type to specify the data to be passed to the action |

## 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](https://www.home-assistant.io/docs/scripts/perform-actions/)

Example configuration:

```yaml
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](https://developer.mozilla.org/docs/Web/CSS/background).

This means your `icon_color` can be:

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

The 5 examples above will render like this:

![Dark icon color examples](https://github.com/bokub/rgb-light-card/raw/images/icon_color_dark.png)

⚠️ 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](https://bokub.github.io/rgb-light-card/test/icon.html)
to convert [material design icons](https://pictogrammers.com/library/mdi/) into CSS

![Light icons examples](https://github.com/bokub/rgb-light-card/raw/images/icons_light.png)
![Dark icons examples](https://github.com/bokub/rgb-light-card/raw/images/icons_dark.png)

### 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:

- Simple text: `label: Red`
- Bold text: `label: Orange`
- Or more complex HTML: `label: 'Blue'`

![Light label examples](https://github.com/bokub/rgb-light-card/raw/images/labels_light.png)
![Dark label examples](https://github.com/bokub/rgb-light-card/raw/images/labels_dark.png)

### Justify

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:
