I would not want anything that requires a cloud connection to be responsible for securing my house. The security record of these smart locks also isn't great.
The final question you need to ask yourself is how they fail safe? There have been Tesla owners trapped in burning cars. If, god forbid, your house caught fire can you get out of your door secured with a smart lock?
Yes, working through a third-party cloud is not ideal, but I have not seen anything that matches the price/simplicity and is self-hosted.
Regarding security, I don't have it so I can't confirm it 100%, but it's not supposed to override the traditional key or block the handle, so you shouldn't have that problem.
If you're set on these devices, maybe have a look at the open-source projects meant to strip Tuya devices from their Cloud dependencies. There's some aftermarket firmware available for some devices. And we have projects like TuyAPI, Local Tuya, tuya-mqtt... It involves some tinkering, but some of these devices work with new firmware or a fake version of the API. And there might be some information on specific devices in the HomeAssistant forum. With a bit of luck, someone already tried it. I generally don't buy devices unless there's some info in the forum.
