For All Ring Pro Doorbell users: This is a MUST for older homes w/ mechanical doorbell Background, I installed the Ring pro and encountered many issues right off the bat. Sometimes there would be no power to the button at all. Sometimes the button would work and the mechanical bell would ring right after but nothing was being sent to my phone. Sometimes the ring would work and send notifications but my mechanical doorbell wouldn't ding. I thought it was my old transformer at first. It was a 16V / 10VA transformer (which is what is recommended) and yet I was getting OK in the health check for voltage. Figured it was a bad transformer so went to Home Depot and picked up a brand new 16V / 10A transformer. Once I took it home and installed it, I got very good for the health check so I thought it was just a bad transformer. NOPE. While the ring now was a bit more stable (it still would lose power 10% of the time) the mechanical bell still only rung like 25% of the time. After poking through forums, I discovered that the 10VA a regular 16v transformer puts out is NOT ENOUGH to give enough power to both a mechanical doorbell AND activate your ring / send notice to your phone. So i went ahead and ordered this guy and replaced it. Needless to say, that was the solution. When i press the ring now, it will ring, send a notification, and chime my mechanical bell almost instantly, without any more issues. haven't had any issues so far - everything seems to work perfectly now. Wish the people of RING knew about this... instead they don't say anything in hopes that you buy a Ring Chime when your mechanical doorbell doesnt work.
