I just received my Ring Doorbell Pro today from Woot (certified refurbished by Amazon with warranty).
Instlled everything (including the power kit). When I apply power the doorbell left light flashes. I tried pressing the setup button on the side to no avail. I tried holding the setup button for 30 seconds to perform a hard reboot to no avail.
I can not get the doorbell to enter setup mode so that I can add it to my ring app.
I have a 16 volt transformer.
What to do?
