--- title: Home Assistant Frontend description: Offers a frontend to Home Assistant. ha_category: - Other ha_release: 0.7 ha_quality_scale: internal ha_codeowners: - '@home-assistant/frontend' ha_domain: frontend ha_integration_type: system --- This offers the official frontend to control Home Assistant. This integration is enabled by default unless you've disabled or removed the [`default_config:`](/integrations/default_config/) line from your configuration. If that is the case, the following example shows you how to enable this integration manually: ```yaml # Example configuration.yaml entry frontend: ``` {% configuration %} themes: description: Allows you to define different themes. See below for further details. required: false type: map keys: "[identifier]": description: Name to use in the frontend. required: true type: [list, map] keys: "[css-identifier]": description: The CSS identifier. required: true type: [list, string] extra_module_url: description: "List of additional JavaScript modules to load in `latest` JavaScript mode." required: false type: list extra_js_url_es5: description: "List of additional JavaScript code to load in `es5` JavaScript mode." required: false type: list development_repo: description: Allows you to point to a directory containing frontend files instead of taking them from a pre-built PyPI package. Useful for Frontend development. required: false type: string {% endconfiguration %} ## Defining Themes ### Theme format The frontend integration allows you to create custom themes to influence the look and feel of the user interface. ```yaml # Example configuration.yaml entry frontend: themes: happy: primary-color: pink accent-color: orange sad: primary-color: steelblue accent-color: darkred ``` The example above defines two themes named `happy` and `sad`. For each theme, you can set values for CSS variables. If you want to provide hex color values, wrap those in apostrophes, since otherwise, YAML would consider them a comment (`primary-color: "#123456"`). ### Supported theme variables #### Primary and accent color Primary and accent colors are the main colors of the application. They can be changed it using `primary-color` and `accent-color` variables. #### State color Each entity has its own color, based on `domain`, `device_class`, and `state`, to be easily recognizable. Theses colors are used in [dashboards](/dashboards/) and [history](/integrations/history/). Home Assistant has default color rules that fit most use cases. Here is a list of domains that support colors: `alarm_control_panel`, `alert`, `automation`, `binary_sensor`, `calendar`, `camera`, `climate`, `cover`, `device_tracker`, `fan`, `group`, `humidifier`, `input_boolean`, `light`, `lock`, `media_player`, `person`, `plant`, `remote`, `schedule`, `script`, `siren`, `sun`, `switch`, `timer`, `update`, and `vacuum`. The color rules can be customized using theme variables: 1. `state-{domain}-{device_class}-{state}-color` 2. `state-{domain}-{state}-color` 3. `state-{domain}-(active|inactive)-color` 4. `state-(active|inactive)-color` Note that the variables will be used in the listed order, so if multiple match your entity, the first matching variable (= most specific one) will be used. ```yaml # Example configuration.yaml entry frontend: themes: my_theme: state-cover-garage_door-open-color: "#ff0000" state-media_player-inactive-color: "#795548" ``` The example above defines red color for open garage doors and brown color for inactive media players. ### Unsupported theme variables Although we do our best to keep things working, the behavior of other theme variables can change between releases. For a partial list of variables used by the main frontend see [ha-style.ts](https://github.com/home-assistant/frontend/blob/master/src/resources/ha-style.ts). ### Dark mode support It is also possible to create themes that are based on the default dark mode theme. New themes can also support both light and dark mode and allow the user to switch between those on the user profile page: {% my profile badge %} Extended example to show the mode definitions. ```yaml # Example configuration.yaml entry frontend: themes: happy: primary-color: pink text-primary-color: purple sad: primary-color: steelblue modes: dark: secondary-text-color: slategray day_and_night: primary-color: coral modes: light: secondary-text-color: olive dark: secondary-text-color: slategray ``` Theme `happy`: Same as in the previous example. This legacy format is still supported and will behave as before and automatically use the default light theme as the base. Theme `sad`: By using the new `modes` key plus the subkey `dark` this theme will now be based on the default dark theme. The final theme rules are determined in three steps: First, the default dark theme CSS variables will be applied, then second the CSS variables from the top level of the theme that are mode-independent (`primary-color: steelblue` in this example) and lastly the mode-specific CSS variables will be layered on top (`secondary-text-color: slategray`). Note: Since this example theme only has a `dark` mode defined, this mode will automatically be used. Theme `day_and_night`: This theme has both a `light` and a `dark` mode section. That tells the frontend to allow the user to choose which mode to use from the user profile (default selection is based on the system settings). Independent of the selection, the primary color will be set to coral, but based on the chosen mode either the default light or dark theme will be used as the basis for rendering, plus the secondary text color will be either olive or slategray. ### Theme configuration splitting As with all configuration, you can either: - Directly specify the themes inside your `configuration.yaml` file. - Put them into a separate file (e.g., `themes.yaml`) and include that in your configuration (`themes: !include themes.yaml`). - Create a dedicated folder (e.g., `my_themes`) and include all files from within this folder (`themes: !include_dir_merge_named my_themes`). For more details about splitting up the configuration into multiple files, see [this page](/docs/configuration/splitting_configuration/). Check our [community forums](https://community.home-assistant.io/c/projects/themes) to find themes to use. ## Setting Themes There are two themes-related services: - `frontend.reload_themes`: Reloads theme configuration from your `configuration.yaml` file. - `frontend.set_theme`: Sets backend-preferred theme name. ### Service `set_theme` | Service data attribute | Description | | ---------------------- | --------------------------------------------------------------------------------------------------- | | `name` | Name of the theme to set, `default` for the default theme or `none` to restore to the default. | | `mode` | If the theme should be applied in light or dark mode `light` or `dark` (Optional, default `light`). | If no dark mode backend theme is set, the light mode theme will also be used in dark mode. The backend theme settings will be saved and restored on a restart of Home Assistant. ### Manual Theme Selection When themes are enabled in the `configuration.yaml` file, a new option will show up in the user profile page (accessed by clicking your user account initials at the bottom of the sidebar). You can then choose any installed theme from the dropdown list and it will be applied immediately. This will overrule the theme settings set by the above service calls, and will only be applied to the current device.

## Loading extra JavaScript Starting with version 0.95 you can load extra custom JavaScript. Example: ```yaml # Example configuration.yaml entry frontend: extra_module_url: - /local/my_module.js extra_js_url_es5: - /local/my_es5.js ``` Modules will be loaded with `import({{ extra_module }})`, on devices that support it (`latest` mode). For other devices (`es5` mode) you can use `extra_js_url_es5`, this will be loaded with ``. The ES5 and module version will never both be loaded, depending on if the device supports `import` the module of ES5 version will be loaded. ### Manual Language Selection The browser language is automatically detected. To use a different language, go to the user profile page (accessed by clicking your user account initials at the bottom of the sidebar) and select one. It will be applied immediately.
