Researched a bit into this some time back and I was not convinced.
It would be nice to have a lock I could assign entry codes for different users and still have a physical key as an emergency backup but the obcession with these locks being tied to an app and/or internet discouraged me.
I stayed with purely mechanical locks with complex keys and secondary arms that make the task to break down a door much harder.
Don't know how it is in other countries but I've been to shops where I specifically asked for locks that would give a locksmith a bad time to pick and was shown a few models where the only way to break it was to put a whole cutter to it and cut out the entire drum.
My door lock is a smart lock but I disabled all ability to unlock it remotely with an air gap. It gives me the ability to use the keypad to lock/unlock without any security holes added.
My smart home system knows it's state too, so I can have it make a chime or alarm if the door is unlocked at certain times. Great for alerting us that our toddler is playing with the door again.
