> I could not enter my own apartment because my phone was dead
Whenever I hear about "smart" devices as a replacement for something that is safety/security critical (like a lock), the question of what happens when the internet and/or power fails is rarely even considered. Does the lock fail open or closed? Does the door open if there is a fire in the building that damages the internet/power wiring? If it fails open, does that mean someone can bypass the lock by simply cutting the network/power cables outside the building?
There might be reasonable answers to these questions at a large business building that can afford fallback options, but I'm not sure there are good answers for e.g. residential situations.
