Ideally I’d like to be able to manage the lock using a open source self hosted home automation system.
If you have a favorite door lock, I’d love to hear it.
I used to use lockstate ($1 a month subscription): per user codes, notification when a code was used, time restricted codes, one time use codes… all very handy features
Keep a key in an exterior combination safe or equivalent, those that need access for a little while get the code to that safe, then you change the code when they’re done. Would that work?
