Go analog.
A mechanical lock vendor makes a mistake, one series of locks break or can be unlocked. Criminals still have to find them.

A "smart" lock vendor makes a mistake, all locks are unlocked or broken. Criminals can compromise them remotely, with full location available.

@beyondmachines1 Also, willing to pay extra for non-smart fridge and washing machine.
@vriesk that's also a fallacy - a device designed to spy on you so the vendor can profit more, then "pushed" in front of you by a slightly lower price
