This offers the official frontend to control Home Assistant. This integration is by default enabled, unless you’ve disabled or removed the
default_config: line from your configuration. If that is the case, the following example shows you how to enable this integration manually:
# Example configuration.yaml entry frontend:
es5 - transpiled so old browsers understand it.
latest - not transpiled, so will work on recent browsers only.
auto - select a version according to the browser user-agent. The value in the configuration can be overiden by putting
latest in the URL. For example
Allow to define different themes. See below for further details.
Starting with version 0.49 you can define themes:
# Example configuration.yaml entry frontend: themes: happy: primary-color: pink sad: primary-color: blue
The example above defined two themes named
sad. For each theme you can set values for CSS variables. For a partial list of variables used by the main frontend see ha-style.ts.
Check our community forums to find themes to use.
There are 2 themes-related services:
frontend.reload_themes: reloads theme configuration from your
frontend.set_theme: sets backend-preferred theme name.
|Service data attribute||Description|
||Name of the theme to set,
||If the theme should be applied in light or dark mode
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.
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.
