For the overhead it’s something like an odd number of cans, an a triangle configuration, IIRC.
FWIW Simple lock manager will let you setup different codes for each user and allow you to configure each user to a schedule. That should handle you, your wife and your maid. It works with a Schlage zwave lock, however I don’t know if it will work with the deadbolt removed. It might be expecting some amount of pressure in order to function properly. But assuming it does work, you can use that project and when an “unlock” event occurs, you can open your MyQ garage door opener.
