False tamper alerts and buzzing

[Sparky61]

My doorbell has been working fine for a couple of months. Now it is posting false tamper alerts and I noticed the chime unit is humming while in standby. None of the posted “solutions” are helpful. Latest firmware installed, correct voltage from transformer. Why was it working fine for weeks and now this?

Tamper alerts come from lack of power from the transformer. Sounds like you may have a faulty transformer so check the voltage at the doorbell.

As I soltage is 18v (within  the specs), firmware is upgraded, deleted Doorbell and reinstalled.

Still getting these errors.

The power supply could be intermittent somehow but tracking that down could be painful. Could simply be a broken wire, perhaps at the doorbell, but anything from the power supplied to the transformer, the transformer itself or the wiring could be the problem. Of course, it could also be a faulty doorbell. For that possibility, use Settings, Support to start the process of replacement.
