I installed fully kiosk app and everything works fine on my android phone.
I use it as a stationary dashboard. But I noticed when home assistant tabs with video content are active (see example) then the screen does not go to sleep.
Is there any solution / fix for that? I assume this is an Android behaviour …
Android tends to keep the screen on when video is playing.
You might be able to find a 3rd party app or do it with Tasker.
The Fully Kiosk integration has sensors and controls that allow you to turn off the display and can be used in automations.
I am using those for now.
