I am assuming you are replying to me -Remove the power pack, Doorbell and connect the wires like they were before the doorbell. Short the two wires to the doorbell button. Does the doorbell chime ring?
Before mounting the doorbell outside I connected a spare AC transformer directly to the two terminals on the doorbell. Configure the doorbell on your workbench with the spare power supply. Make sure the app is set to mechanical chime.
Then re install the power pack and doorbell outside. Have someone push the doorbell button outside.
If you only hear a buzz when the doorbell button is pressed then more than likely need more amperage. Taking the cover off the chime and looking at the plate between the two chimes you will see the model number and voltage which should match the current transformer. Mine chime and transformer were marked 12VAC.
There is a post above relating to what you should see in the power pack.
I don't recall having any issues with the mechanical chime prior to installing the ezviz. The ezviz powers on, I got a reading of 20v across the back of the 16v/30 transformer I recently purchased from HD. If I remove the power kit from the circuit, I got a reading of 4.8V at the ends of the DB and transformer wires, when i connect the wires to the mechanical chime without the power kit I will hear a humming sound; when I did the same but with my old transformer the mechanical chime would lightly ring every 5-10 seconds on its own without me tapping the doorbell button in addition to humming.
Old transformer spec: 16vac-10VA
new transformer spec: 16vac-30VA
I'm starting to believe what @David L said that its most likely an ezviz server issue. I wish I had more reasons to investigate more, but my wife would kill me if i purchased any more tools to test things out, thanks for the suggestion tho @pete_c
