As reported by some testers (thanks guys!), DoorBirds with firmware version 000111 do not report motion events.
As shown here: https://www.doorbird.com/changelog, this functionality was only added in firmware 000112.
There does not appear to be a way to initiate firmware updates on Doorbirds. You must wait until it is "pushed" to your device. It appears that the firmware is slowly being rolled out.
