After returning from some consulting work for a new client, I spent several hours trying to figure out why our doorbell chime had ceased to function. A visitor for Jeanine arrived this afternoon. I was in my office and heard the driveway sensor signal the presence of a car. I looked at our security camera feed and saw her friend walking up to the front door. I was puzzled when the doorbell did not ring. When I let her in, she confirmed having pushed the doorbell button. After confirming that the doorbell camera/button was working, I searched online for the applicable documentation and began to troubleshoot the chime. I did a factory reset and attempted to re-pair it with the doorbell. When this did not work I created a support ticket with the manufacturer (Reolink) but will probably not hear back for some time. Because the doorbell has a working chime on the outdoor unit, guests will be under the impression that we have heard the indoor chime and they will have no reason to knock. For this reason it is fairly urgent that I get this situation resolved. I eventually decided to purchase a replacement with overnight delivery. Had I known that this would only cost $19, I would have started with this solution in the first place. I should know by tomorrow if this cures the problem.
