Android Widgets

The Android Android app allows the user to create widgets on the home screen so the user can perform a variety of actions like perform an action, display the state of an entity or even render a template. You can add the widget like you normally would for any app depending on your devices launcher. The widget will not work when Data Saver is enabled, you will also need to ensure that background data for the app is enabled. If you notice that a widget is no longer working try to recreate it. Widgets can also be edited by navigating to Settings > Companion App > Manage Widgets, if you are on Android 12 you can also edit the widget by long pressing it and clicking on the edit icon.

Widgets can also be added from the Manage Widgets settings page, as long as the device supports it.

Template​

This widget will display any text that you wish to show in a widget using Home Assistants templating feature. This is an advanced feature but allows the user to display a wide variety of data. The template will be updated instantly on relevant states changes. When editing the widget, the template will be shown below the text field so you can preview what it would look like.

You may also use HTML to format the text displayed such as adding a new line (<br>), making something bold (<b>) or large (<big>), changing the color (<font color='#03a9f4'>) or aligning it to the start or end of a line (<p style="text-align: end">).

If the template in the widget isn't updating instantly, you're most likely hitting rate limits. Try optimizing your template to get faster updates, or tap on the widget to update it manually. You can also use the preview in Developer Tools > Template to test your template updates.

  2. Scroll down to Home Assistant in the widget list
  3. Drag the Template widget to an open space on the home screen

Theming​

Most widgets allow selecting a theme to use. The available themes depend on your device and the specific widget. Possible options are:

  • Dynamic color: uses the colors from your device and wallpaper to make the widget fit in with your home screen and device. This theme is only available on supported devices running Android 12 or newer.
  • Light/dark theme: uses your device theme to make the widget fit in with your apps.
  • Transparent: removes the widget background and allows you to set a text/icon color, to make the widget stand out less.
