Hi I upgraded my ring pro hardwired doorbell that used a greenbrook dht01a-c. Everthing worked fine via the ring transformer. I upgraded to the new ring pro 2 as it had more features and again its own transformer. But this time when I changed the door bell and the transformer the mechanical chime stopped working. After a few calls with ring technical support they said this chime wasn’t compatible. So I checked the list and got a Byron 765. The app settings are good in that the chrome type is still mechanical and the transformer voltage is 23v. I was told then untold that I needed a power kit so not sure how I can get this mechanical chime to work. Each chime has 4 terminals, with terminal 0 connected to doorbell and terminal 3 connected positive from transformer. Can anyone assist pls? Thanks in advance.
