I'm trying to find a garage door opener that automatically closes
after a preset time.

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.

I do some volunteering in a commercial
building which has such a door
system. It actually turns on an exhaust
fan for a few seconds when the
door moves. I really don't know what a
few seconds would do for
removing CO. But, if the door is left
open, after about a minute, it
closes. It does have an infrared
detector about 2 feet from the floor
which will stop the door from closing
and actually reverse it. BTW,
the funny thing about the whole design
is that if you don't want it to
close, you simply stop it before it
reaches top. It will then stay open
forever. We use it that way all the
time while loading and unloading.
Pretty stupid design if you ask me.
