I want to go automatically from View to View like a Screen Saver when Tablet is not in use.
Is there a way to do this?
This is an awesome idea! I would really like this feature as well. Did you ever get something going here?
There are a few options here - depending on what you are using on the tablet. You either want to be using something like Fully Kiosk that will let you change what page the tablet is showing - in an automation, or BrowserMod via HACS which will let you do the same.
Then you create an input_dropdown helper and fill it with the dashboard name and view separated with something like a |
so that you end up with things like this:
lovelace|home
lovelace|lighting
lovelace|temperature
lovelace|media
energy|0
lovelace-cameras|0
Then you create an automation that runs on a time pattern to select the next item in the dropdown (or even choose it randomly).
Create an automation (or ideally use the same one) to react to a change in the dropdown, and then use a choose to check each tablet to see if it is in use or not before issuing the command to change the active view.
Remember to split the item state from the dropdown box:
{% set p = states('input_dropdown.tablet_views').split("|") %}
{% set dashboard,view = p[0],p[1] %}
