If they rely on a central server, what guarantee do you have that it won’t all go to shit with no warning? You certainly can’t rely on the economics of the situation, so what’s left is relying on some nebulous concept of “reputation” and that has been proven over and over again by the largest and smallest companies to be worthless…

They need the central server/phone app to be initially provisioned, but they can be controlled entirely locally after that. No phone app needed.

I'd prefer completely open, but I haven't found anything as well made and inexpensive that's also open.
