I recently purchased a ring doorbell pro. I have a very old existing doorbell, however it's not worked for a long time. That is to say I don't think the chime works anyway and I'm not worried about it working.
So I pulled new wire through from my old doorbell to the transformer. So I was going to connect the Ring Pro directly to the transformer. There are a couple possible concerns though. First, my transformer is putting out 25.3V so a little higher than the 24V listed. Upon researching to see if this slightly higher voltage is a concern I came across the next concern. I've found multiple posts/articles that mention you can't directly wire to the transformer without something else inbetween. I've read different things though I've seen some posts that say I need a resistor, others say either the Pro Power Kit or the Advanced Power Kit.

Hi @Dwain77, thank you for being a part of the Community! You will want to use a Pro Power kit for this installation type to regulate power.
That's exactly what I did. I was thinking that the Pro Power box had to be inside the chime. I wasn't thinking about just wiring the box in line with my cable to the doorbell. It's working great so far.
Thanks for the reply.
I tried wiring my new PRO directly to the transformer and the transformer overheated almost immediately. So... does anyone know how to do this with the existing doorbell wiring? If there is a way to do this, I would get rid of my old chime system and plug in a ring wireless chime for my PRO doorbell and my doorbell 2(which is on my side door). Any help out there?
I wired my Pro directly using the Pro Power kit inline and haven't seen any issues. Maybe your transformer is underpowered?
My setup is Transformer - Pro Power kit - Ring Pro. The Pro Power kit can be put on either line, just cut the cable and push the ends in the bypass like you see in this article.
I did the same as @Dwain77.
I replaced my 20 year old 16V 10VA doorbell transformer with a new 16V 30VA transformer.
It wasn't clear to me if there would be any added benefit using a 24V transformer instead of a 16V.
My Ring Pro works great with the 20 year old doorbell chime.
Like Natey, I also replaced my old 16V10VAC transformer with a newer transformer. I chose a 24V40VAC model, and I'll also be using the original mechinical chime in the house. Have a Ring Pro arriving this week so I'll see how well they play together.
