Show dashboard view via Google Cast

Use this action to show a specific dashboard view on a Google Cast device, such as putting your downstairs overview on the kitchen display. This is the Home Assistant Cast feature you trigger from an automation or script.

You pick the Cast device, the view to show, and optionally which dashboard the view belongs to.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To show a dashboard view from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create automation > Create new automation.
3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
4. In the Then do section, select Add action.
5. From the search box, search for and select Google Cast: Show dashboard view via Google Cast.
6. Select the Cast device in the Entity field, and enter the View path to show. Optionally, set a Dashboard path if the view is not on your default dashboard.
7. Select Save.

Options in the UI

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as cast.show_lovelace_view. A basic example looks like this:

action: cast.show_lovelace_view
data:
  entity_id: media_player.kitchen
  dashboard_path: lovelace-cast
  view_path: downstairs

This shows the downstairs view of the lovelace-cast dashboard on the kitchen Cast device.

Options in YAML

Good to know

• Only administrators can run this action.
• Home Assistant Cast requires your Home Assistant installation to be reachable over https://. If you use Home Assistant Cloud, this is already taken care of. Otherwise, set your external_url.
• Each dashboard view needs a path defined for the View path to work. See the views documentation.
