I’m looking into installing a door lock w/ key pad at home for two use cases:
- I’m out of town and need to allow someone to enter my home, in an emergency or for any reason.
- Nice to have - “oh shit, did I lock the door” - ability to lock the door remotely from my phone, would also solve use case #1 by unlocking remotely.
If there are no privacy respecting / self hosted apps for remote control (use case #2), then a “dumb” electronic lock w/ key pad that enables me to set a PIN that I can give to a friend or neighbor in a pinch and then reset the PIN after I get home, that would be good enough. If no such keypad/electronic locks exist, then my backup plan is to just make a few copies of my key for trusted friends & family and/or hide a key, but I’d like to explore the keypad route.
Something that uses the Matter protocol might be what you’re looking for. My understanding is that they can be disconnected from the internet (only able to communicate with your Matter controller over your local network) and still work.
Maybe something like this:
