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.
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.
How do you keep getting locked out? Would it not be easier to remember your keys when you go outside?
No no, surely the solution to this is a mechanical one

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?
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!
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
