I went back a re-tested this doorbell with R083, and it seems to be working for me now. To ensure that the Almond+ receives a notification when the doorbell button is pressed, you need to change the doorbell device "send notifications" parameter 80 (1 btye) from 0 (nothing) to 1 (hail CC) or 2 (basic CC report). I don't know why Aeon Labs has this off by default. I'm not sure if R083 actually improved anything, or if just happened to get the configuration parameters set correctly this time.
