Sure, What’s on your mind?

Sure thing. What do you want to know? Why would anyone give up their home intercom system when it can be integrated with the Nest Hello or Ring Pro? The electronic chime from these home intercoms rings all the room, patio, and ceiling speakers throughout the house. It’s very cost effective and you don’t need any extra plugin devices. Makes since to me. Cheers & Beers!! dB

I found a very instructive YouTube video titled "Connecting a Ring Pro Video Doorbell to the electronic chime in a Nutone intercom" dated 8/20/2018. It explains (shows): How doorbells work in general and are wired; how to wire up a Ring Video Pro to a regular doorbell; AND how to wire up a Ring Video Pro to a Nutone intercom in a manner that still causes to Nutone Chime to play when the button on the Ring Video Pro is pressed. The video is quite instructive and the process does not appear to be complicated. I don't have anything to try to sell to anybody, so I'm just going to try to explain it to you below. You must purchase an AC Relay to act as a "trigger" for the chime on the intercom system (that's all that the doorbell pushbutton you have now does, but by attaching the Ring Video Pro to those old doorbell wires, you're effectively removing that "trigger" that used to send a signal back to play the chimes. so this relay serves as a new "trigger" to start the intercom's chimes to play). The video includes a screenshot from Amazon showing a 24V AC Relay that can do this and it's under $10.00. If you happen to also have an actual 16-24v doorbell transformer (your intercom doesn't have one), then you may not need to buy anything else. [I'll add here that I've seen a few posts from folks saying that sometimes a 16v transformer isn't quite enough with the Video Pro, but they also report that a 24v transformer works great.] However, if (like me) you have only the intercom (mine is a Nutone IM3003) system with its chime and NO separate doorbell transformer, then you'll need to get a transformer, too. Again, the video includes a screenshot of an appropriate (24V 40VA) AC transformer that's only about $20.00. (I found a different one on Amazon with the same specs, but that comes with 25' of wire already neatly attached. It's not much more & saves a little work). That video includes hand drawn electrical diagrams for all three of the wiring possibilities noted above, along with showing him testing with a multimeter during the video to illustrate what's going on, so you can really learn, rather than just following a list of steps, but not really understanding what you're doing. What I don't understand is why Ring doesn't offer an optional product that combines such a relay and a transformer in one little box and sell it for $29.99? Lord knows the parts would be cheap enough to buy in volume and the wiring is simple. While watching that video, I took some screenshots to help me remember what to do (and buy), then I plugged those into a Word document with a few minimal "reminder" annotations, then made it a pdf file. Thinking you may find it useful, I've attached a copy of that pdf file here. But I know it's going to be better if you'll find and watch that video itself. So you'll know: I didn't make the video and I don't know they guy who did. It just seemed good to me.

Sorry, I forgot one other thought I wanted to mention. Because we have fairly frequent power outages here, my router already is plugged into a relatively inexpensive battery backup (Amazon branded 800VA). Now, the transformer I'm using with the Video Pro will also be plugged into that same battery backup. That way, I think both essential elements of that system should stay up for at least a few hours when we have a power outage.

First of all, Ring or Nest Hello have no real interest in providing a way to connect your existing intercom system door chime to their system. It's pure economics. If that's not enough, How about connecting old technology with new technology? This isn't the 60's, 70's, or even the 80's. Everything is possible within reason. I can park a 747 on my mailbox if I choose. Practical? Of course not. I figured out a way to connect Ring Pro, Ring 2, Nest Hello, and Energizer to any existing intercom door chime. I also provide phone support. Yes, I do charge for this kit, but I make it as easy as possible for anyone to install it. Kit, wiring diagram, phone support, All for $129.00. dB

Jon, This Kit was designed for intercom systems but will also work with some phone systems. If your door speaker can be triggered by dry contacts or a relay, Then it could work. Darrell

Cool. This sounds like what I'm looking for.

What is it that you would like me to share?

Reading between the lines of your original post, it sounds like this kit is something you want to sell, but I wasn't 100% sure about that. I didn't know if it was really just a schematic that you were wanting to share with people or if you were wanting to sell it. Sorry if I didn't understand your original intention. I am interested in it, and I'd like to hear more about the kit -- what all is in the kit, how it connects to the Ring Pro, how much you're asking for it, etc... Thanks. :-)

Hi @Wirenutman as you know selling items for your own business is not permitted in the Community guidelines. However, we would be interested in hearing more about the solution you found, that could benefit @JonS . I know other experienced electrical DIY neighbors have used a finder relay, which can be used to connect the Video Doorbell Pro and the intercom. This also requires a 24VAC transformer and the Pro Power Kit to be used as intended. Is that similar to the solution you found? \*We recommend hiring an electrician for any electrical work.

The 5006 will work the Ring Pro and my kit.

How does one go about obtaining your kit?
