But that does not require that triggers be logically AND…
What you have described can be accomplished with a State trigger based on a Group, a Template trigger (see Post 17), or a State trigger and state condition that contain all three sensors (see Post 12).
I see “When DM Escalier changes from any state to Clear for 1:00”. This has no meaning. I assume it means “When DM Escalier changes from any state to Clear and remains at state Clear for 1:00”. If this is the intended meaning, then it does not work: when I exit the stairs, wait for the motion detector to clear, then quickly return to the stairs, it turns off the light instead of restarting the automation as it should, since the automation’s starting trigger should be… well, triggered.
Default mode for automations is single. If you try to retrigger it while it’s still in the 1 minute timeout for clear, nothing will happen because the automation is still running.
If you want your automation to retrigger, all you have to do is add mode: restart at the bottom of the automation and job done.
There’s an option to do this in the UI too, but I can’t remember where it is or what it’s called.
