Hello, I installed my DB Pro a little over a week ago. I have no existing doorbell wiring, so I bought the below 26 ft transformer off Amazon. I needed the extra length as the Ring adapter is not long enough. It’s a 24 Volt power supply, and I measured it with a multimeter to see that it’s supplying the correct voltage, which it is.
I’m not having any issues whatsoever with my DB Pro, and experience no symptoms of insufficient power–it’s working absolutely perfectly. The ‘Doorbell Kit’ in the app is correctly set to ‘None.’
However, when first installed a little over a week ago, my voltage was well above 4,000 mV. The voltage continues to drop by 8 or so mV each day, and I’m currently down to 3,938 mV.
Is this normal? Will it reach a certain point, then recharge the internal battery? I’m worried I may eventually experience power issues once this drops low enough, and am trying to proactively address this before I have problems.
