Zone in active for x time straight

I would like to trigger a flow like this.
Last person leaves the house… if zones 1,2 and 4 has been inactive for 30min straight then run flow x

Do you have a Homey (cloud) or Homey Pro?

With a Pro, this is a way to accomplish that:

PRO with advanced flows

Guess you could do it something like that but it’s rather messy…
I think I will use a homey script for now and when (if) there is a ready card where I can just set “If zone x has been inactive for 35min, then …”

Did athom not build that card into advanced flow?
Normal flow does have it:

Edit:
The card is there but it lacks flexibilty… (no 35min)
