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
If I have a friend coming over, I’d like to be able to give them a time limited code to use. If I have a repairman coming over the same.
Physical keys work fine, but once I tasted the sweet freedom of giving a friend one of my backup codes so they could drop something off while I was across town was amazing.
Any z-wave or ZigBee lock like those from Schlage are great. You can then integrate it into Home Assistant where there are great integrations like keymaster that make it super simple to do management like what you’ve mentioned
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?
