Automatically change shown entity in Lovelace

Im trying to figure out how to have a Lovelace card that can automatically cycle through certain entities that I choose, based on a timer. Example: every 30 seconds the Lovelace card would just cycle these entities, one at a time, instead of taking up all this space.

There may be more elegant ways to do this but:

I’d create an input number helper to hold a number that indicates which entity to display. 1 to 11.

I’d create an automation that runs every 30 seconds to increment the helper and then reset it.

I’d then use a number of conditional cards that display the required entity if the input helper is a particular value.

ok let me give that a try and see what happens. Thank you for your input on this.
