Hello, I have a Generation 2 Ring Video Doorbell, purchased in XXXX. A little while after purchase, I bought a plug in power supply (not from Ring) whose output was 24V AC. This failed recently and I decided to buy a Ring-made power supply. When I received this I found it’s output was 24V DC. The instructions that came with it indicate that it will work with my doorbell but I note that on the reverse of the doorbell it says it is to be used with a 24V AC supply! I have connected it to the Ring 24VDC supply and it appears to work! I was looking for an indication that it was on mains power and i can see at the top of the doorbell device page there is an icon of a battery (all green) with an electrical “flash” in it. Does this indicate the device is on mains power? Thanks, Jim
