I have one too but it has an emergency physical “master key”. Also there’s a port to provide power to it through a battery bank, in case you really run out of juice though it’s potentially another point of failure. No internet connection
I have a Nuki this one still works with a normal key, since you install it on top of your existing double cylinder (you should only install it on one that can have two keys inserted at the same time or with a turn knob on one side). The Nuki just turns the key or thumb turn of the cylinder. Also means you can’t see that a smart lock is installed from the outside. Battery is not a problem since they last for about 5 months. And you get a warning when it reaches 20%.
