Action delay time works well, but it is only available if you are using a presence option. In this particular thread, the OP is basing everything off of the lock being locked. So “action delay time” is not an available parameter for that. It’s also not available if you’re just using a switch.
I suppose you could have locking the door turn on a virtual presence sensor but at that point you’re using the same kind of chain as I described, just with a different set of devices.
So you’re right that option exists, but it only exists for Geopresence.
