Leaving it on won't do any good, if it's not connected to your wifi it won't update or anything. Does it talk when you connect it to the power when the white light is spinning? How is is being powered, what kind of voltage do you get from your doorbell transformer/wiring?I got a Ring Pro today, wife found it in an 'open-box' store. Got it all fitted and it doesn't power on. Spent all evening on the live chat with their support and it sounds like the unit is faulty. They've said to leave it on to see if it comes back to life overnight and if it doesn't, they'll send out a new one. It didn't have any security screws in the box either so hopefully there aren't any chancers going by tonight, although saying that my front door was left unlocked Sunday - Wednesday so it should be alright!
