I have a few sneaky tiptoeing but loveable miscreants as part of my family and I would like to keep them out of my office. I’m sure some of you can relate.
My problem is that most of the locks I’m finding are big, heavy, super-secure deadbolts. I don’t care about the actual security, I just want a simple interior lock that I can open with a pin/NFC/fingerprint and also log entry and exits in HA. Does anyone know of a lock that’s more “lightweight” than the common options. After all, if they make it into my office there will be evidence all over in the form of fingerprints on the window of my PC case! :-D. I just need a mild deterrent.
The wife already nixed a motion sensor turning all the lights red and triggering horror movie sounds.


Any smart lock should work on an interior door, you may have to drill a deadbolt but its the simplest solution. Switchbot and U-tec both make smart locks with fingerprints and excellent Home Assistant integration. Ubiquiti also sells magnetic latches you could install for access control if you’re in their ecosystem.
If you can give up on Home Assistant integration/smart features, however, there are oodles of push-button and even fingerprint door (without other connectivity features) knobs out there. Most of them are terrible quality and not secure but that doesn’t really matter to you and they are cheap.
The second part of your comment rings true for me. I guess I could just put a dumb lock on the door and use a simple motion sensor to let me know if someone is skulking around.
Why not just use a door sensor to tell when it’s opened?
