I concur. I can see why a doorbell might have a cooldown/lockout feature if someone is getting hammered by a prankster, annoying kid, or something of the like, but I’d expect that to be a user-selectable setting in the app.
I don’t know how the previous doorbell models’ behavior compares, but perhaps this is one of the things that’ll be ironed-out with a firmware update since this is such a new product. That’s my hope, anyway.
