Appears to be a dead product. Probably don't use, likely insecure
I was an early adopter of this product since I'm a die-hard homekit user and this was the first doorbell available. A year and a half in, I've seen zero firmware updates andouie no feature updates to either the iOS app or the doorbell itself. This amount of time is like two lifetimes in the world of IoT device. I'll be replacing this soon with either a Logitech or a Eufy doorbell. Very disappointing.
