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.
If you don’t mind me asking, why do you have such a door in your home?
Lives in a bank vault.
As one does.
Maybe just a spare key in a hidden lockbox outside?
You could also look at these.
With the WiFi add on it’s HA compatible.
Does it work in local only ?
In Bluetooth mode yes.
But that’s not with HA integration, still using a proprietary app. Lame
At some point way back when, Adafeuit was selling empty shells of the original lockitron… I really wished I’d gotten one of those!
The issue is going to be that you need 3 full turns. It also sounds like you’re not actually describing a “knob”, meaning a normal doorknob, but some sort of metal wheel.
Picture may be more helpful, but it certainly sounds like nothing would exist for this.
Can you share pics with this door? How do you walk outside and have it lock behind you?
When you close it, it’s not possible* to open it again from outside
* = only the triangular piece engages, so a professional can unlock it from outside by using a thin sheet of steel
Wow. Do you live in a bank vault? That’s a serious door!
There are so many burglars here that this kind of door is the standard in any apartment

Not sure if it’s compatible with your particular lock, but I’ve got switchbot stuff integrated into home assistant without issue (using their hub).
Nice this looks compatibile, except for the open sensor, my door has an ultra thick frame and it’s only possible to install it at 12 cm, while the guide says 4 cm max. Does it really need it?
It is used to detect closing of door and lock the door once it is closed. You may need it during the initial setup. as long as it can be placed close to the door lock, it should work ok.
otherwise, once integrated with HA, you can probably use your own contact sensor and trigger door lock using HA
btw, i am using ESPHome bluetooth proxy with Switchbot
