3.5 days = 84 hours in seconds still 84 hours delay? What do you want to start delayed with 84h?
Pls describe what you want to accomplish for a scenario not the way you thought but didn’t finish.
your Period Card is a condition, either date between or time between, but not date&time between other date&time. if you use both cards it will have impact it wont run any night.
If you want to enable / disable something over a long time you need two flows / two triggers each with a date/time one start to enable and one end to disable. or a schedule (2 x an alarm) or one of the 3rd party apps (maybe possible with Homedall? or… I don’t know.).
The enable/disable can be a Tag or Virtual Switch. (HouseIsRented = true)
Flow 1: Enable When Time (or an Alarm Start) , then HouseIsRented = true
Flow 2: Enable When Time (or an Alarm Stop) , then HouseIsRented = False,
Other Flow: When Motion detected, and HouseIsRented=True and between xxh - yyh, then Lights On and Start CountDown Light 3h and Start CountDown Cleaning 10h
Other Flow: if CountDown Light = 0 and Door is Locked, Lights Out, (? Why 2h59 after locking the door? but Ok.)
Other Flow if CountDown Light = 0 and HouseIsRented=False then Start Cleaning (this can trigger more often if there is motion, but add a counter to stop triggering if you want.)
This last one will not trigger if there is last motion more than 10 h before end period. but you can fix that…
