Show card when lovelace view is empty

What would be the way to show a card if all other cards are hidden?
My default view has cards that show e.g. all lights that are on, one card to control climate entity when it is on, open windows and some conditional cards. Point is that these cards are not visible if everything is ok and devices are off. Currently I use conditional card and custom card auto-entities.

But if the view is empty I’d like to have a card indicating with a text that “Everything OK”. Instead of having the view blank.

I can only think of making one card including all the other cards conditions but that seems very hard to maintain.

Config below

  - badges: []
