Following up on my own post (and just in case this might be useful to someone else), after working pretty reliably since I originally installed it last November, my Video Doorbell v2 in recent weeks stopped activating the mechanical chime.
Initially, doing a Restart in the app got the chime working again…for a few days. When that no longer worked, I contacted Wyze Support. At that time, the only way I could get the chime to work was by holding in the doorbell button for 1-2 seconds, but eventually that also ceased to work.
One of Support’s recommendations (which I’d previously read here on the Forum) was to set the Doorbell Chime Type to Digital and set Ring tone length to 2-3 seconds. When I tested that, 2 seconds resulted in a long buzzing sound in addition to activating the chime, so I set it to 1 second which worked better (sounded the chime without the additional buzz/hum) when I tested it at the time but then failed to chime a few hours later when I had a UPS delivery.
Wyze then suggested a replacement, and I asked if trying the alternate wiring instructions for the Chime Controller would be worth the effort. I didn’t figure it could do any harm, so I disconnected the Chime Controller’s white wire from the chime’s FRONT terminal and left it disconnected. I then disconnected the Chime Controller’s red wire from the chime’s TRANS terminal and connected it to the FRONT terminal. When I restored power and tested, there was a ding-dong and also an unpleasant rattling sound for a few seconds. I checked the app and saw that it had Doorbell Chime Type set to Digital and Ring tone length set to 2 seconds (I had fiddled with settings while trying to get the chime to work again after it failed with the 1 second length). Setting it back to a Mechanical chime type gave a better result, though there’s still an occasional rattle from the chime box.
So far this is working the next day. I asked Wyze Support to keep the ticket open for a few days for me to test, and I’ll plan to follow up there and here.
I’m puzzled by why this works. The Chime Controller really is a little black box of mystery to me.
I just don’t want my chime box to think it’s a U2 album.[1]
