As per LG WebOs: How to use "current_app_id" in automation?, it would be great to be able to detect when the TV is on the Home screen, perhaps by exposing the client.current_app_id
as a media player attribute, or by adding Home screen to the list of sources.
The ‘Source’ is currently not useable since it doesn’t include the Home screen, only the most recent source other than this.
This would allow automations to be triggered when the TV returns to or leaves the Home screen, such as changing lighting in the room.
