I'm trying to find a garage door opener that automatically closes

the only thing I'm finding is an aftermarket 'butler' that works
wirelessly, which is fine, but do any openers have this built in?

I've never seen one and seriously doubt that any opener manufacturer
would offer such a thing because of the obvious liability issues with
unattended closing.


that makes sense, but I wish they did - we had a car stolen after
leaving the door up



So have a decent security alarm company install a photoelectric or IR
detector across the door opening which activates after that "preset
time" you mentioned and will trigger a "burglar alarm" if a person (or
car) passes through it.

Not eggsacklt rocket surgery for a decent alarm guy to figure out how to
make that up.
