There has been a few times when my chime doorbell (The box that makes the noise that’s connected to the ring video doorbell) goes offline and I am completely unaware & end up missing people at the door who ring the bell & nothing can be heard that they are there.
The only way I can tell if the chime doorbell has gone off-line, is if I check on the app.
An improvement would be if any of the system goes down or off-line then a notification is sent via the app and issue a follow-up email.
This wouldthen prompt you to fix the problem or reconnect.
Ths same notification idea should apply when the Ring video doorbell goes off line.
