What device can rotate a knob and works with HA? (feddit.it)

I was accidentally locked out of home again, and I had to call a professional to open the lock.

But if someone was home, they could have just turned the knob of the door from inside. There's a device that can do that? It needs to do 3 full turns and it requires a bit of force to do that (armored door with iron bars that slide in every direction, so it has a big inertia to start)

I saw a ready solution on a store, the iseo x1r, but that costs 1000 euro + another 200 for the gateway (not mandatory but otherwise it uses proprietary Bluetooth protocol and so it can't talk with HA

It sounds like you have a heavy duty door lock to be very secure, but you are essentially trying to backdoor all that security with a new internet-connected thing. An adversary only has to break the weakest link here, rendering the physical door lock obsolete.

If you are just going to have some digitally-connected device ultimately controlling access to the house, I'd go with just some standard door lock that does that (i haven't used em but they exist). The physical lock on those is surely less what you have know, but with your proposed solution the physical lock probably isnt what people who crack anyway.

Yes, but now you’re weakening two aspects of the security, not just one. And for the digital solution you would also need to (break into the network + break into HA) -or- (break zigbee/zwave/thread) + be physically present to take advantage. I would argue this is generally more secure than a mass-produced lock with unknown vulnerabilities that’s easily recognizable from outside.
