Wiring the ratgdo 2.5 board into a LiftMaster garage door opener 

Thanks so much for making this video! I was super excited when I got my RATGDO in, but after looking at the wiring diagram, I got nervous that the install would be a lot more difficult than I was hoping. After watching your video and pre-wiring my RATGDO, installation only took me a few minutes!!

"So we can give the middle finger to chaimberlame for screwing us all over!"😁 Love it! Great tutorial by the way for anyone who is curious about the wiring... Now just waiting for my ratgdo (s) to arrive!

OUTSTANDING! Grabbed the ladder and beat up iPad and followed along. I don't comment on videos much but this made the install super easy. thank you.

This was really really helpful. I've never wired... and was intimidated by the diagram.. Thank you for doing this.. Was able to do it quickly after studying this.

Got my board today i am itching to show my middle fingure to MYQ hopefully shortly.

Thanks for a great video, I don't know what MyQ Chamberlain was thinking.

Really nice work! I am looking to power the board off that low voltage connection. Have you explored that at all / found resources on how? I just got my boards, installed the software and connected to my network. Wiring is next.

Thanks for the video - helped a bunch to retire my dependance on MyQ and get my garage opener into home assistant. The ESP32 integration worked great with my ratgdo 2.5i. The ESP32 version of firmware has some really amazing features, not available elsewhere.

Thank you! Once you said it was a passthrough it all made way more sense!

Super helpful. Was able to get mine up and going quickly because of your video. Thank you!

Yo thanks a lot, hope everyone that gets their ratgdo boards find this easy. Very helpful!

Thanks for the video, especially the part on how the terminals worked. It wasn't obvious to me. Ratgdo is now installed and working!

Just got mine and this is the exact info I was looking for. Appreciate it! (-EDIT- wow I just noticed you just uploaded this like 30 min ago lol Couldn't have had better timing)

Thanks for the video! This really helped me out, oddly enough I found your reddit comment after this video.

Appreciate the video. Just ordered my board today. I was looking at the wiring diagram and scratching my head. This is helpful. Looks like a breeze! And now I wait for the board to arrive…

Thank you for this video, makes the RATGDO more appealing to even novice users! More people boycotting MyQ is a great thing

I used just an ESP32 which cost $4 and works just fine it also has extra button for open/close which allows me to hit the button once....get out of the garage and 60 secods later it closes automagically......

Thank you SO much for making this video! I’m about to do this to multiple garage doors this week!

I ordered these devices. Shame on Chamberlain for being greedy bastards. What finally motivated me was seeing that Home Assistant is CarPlay capable. Now, I can open the doors from my car's screen. Pretty awesome! I love Home Assistant.

thank you so much for this video!

Thanks for this video. Glad I wasn't the only one that found the wiring confusing

It's interesting to me that so many people need a video like this. Why aren't the specific details mentioned on the ratgdo website. I couldn't find anything that explicitly said i need to buy wires and a wire stripper or what kind of wires and how to strip and do a good job of it.

Thanks so much - very helpful and share the sentiment on MyQ & Liftmaster/Chamberlain. I've been wanting to get rid of that mess for local control for a long time and this has pushed me over the edge to go the RATGDO route. Thanks for the great video - will be using it when mine arrives hopefully shortly!

Super helpful. Thank you for taking the time to make this instructional video!

I see you using the left side of the white hole here but I've seen other photos using the right side of the white hole. Are these different connections?

Very helpful Thanks.

Thank you very much Mel🙏, after instaing this case we still use the myq app will everything work just like before?

Helpful!

Thanks for the video. Very helpful.

You are my hero 🙏

Thanks for this! Definitely will be referring to this when mine comes!

I’m running a Ratgdo with a Control4 system. I just used the 3 wire leads (red , white, and black) and twisted them together with the existing leads. I didn’t have to use any of the other connections or pass through ports, works just fine. I also used a 3m fastener to stick the board directly to the back (I have the same motor as you) There’s a flat space next to the serial numbers you can just stick it to, no mess, and secure. Cheers.

I understood the diagram fine once I looked it over, what I don't know is any coding needed for setup/integration. I've been contemplating getting one myself.

There are 2 issues with the site/docs and 1 with the physical product that jumped out at me right away. 1. The site shows wiring and mention of a 2.52 board but AFAIK, the latest board to ship is 2.5i - I just got my board over the holidays. 2. The diagram on the site shows the bottom of the board instead of the top. This needs to be changed as when you're using the terminals you'll be pressing them from the top. 3. The terminals are too small to fit anything but the smallest of ferrules - if you're going to use stranded wire, you should always use ferrules - I had to use bare solid wire for some connections. I'm seeing a couple of issues with mine. The first is that the obstruction sensor often stays on "detected" and won't clear. Lastly is that on my Security+ 1.0 LiftMaster Jackshaft there's no "opening" or "closing" status and both UP/DOWN controls are the same thing, just a momentary button. In other words there's no dedicated OPEN and CLOSE commands. Need to find out if replacing the keypad with a different version can remedy that.

Just received my RATGDO board after 3 weeks wait for back order. Gonna follow your instructions to install..

Hey so I have two wires in my black obstruction on the the garage door opener. One is red other is black-white but both were plugged into the same terminal so what do I plug in the ratgdo

I want a clean garage...

If you want to make those low-voltage wire terminations really nice and clean, look into a ferrule crimper. I've even doubled up conductors into one ferrule. They're really essential for stranded wire with push-in connections.

You mention plugging it into a 5V USB power adapter. How many amps is that 5V USB adapter? (i.e. how many amps does the RATGDO need?) Most of my 5V USB adapters are only 1 Amp...is that enough?

Besides being able to operate this if the internet is down what is the benefit of this over the liftmaster wireless operation?

It would be nice if you did a video on how to download software as well. Great video...

Just curious what is that other red wire for that thats plugged into your GDO?

Works with Google assistant?

While the video is really helpful in reality, all you have to do is run wires directly from 3 ratgdo connections on theboard to your 3 connections on the chamberlain - you do not have to remove wires from your chamberlain to the ratgdo board - he refers this to this in the video but just did the installation another way - in my opinion, the hard way. No need to use the pass-throughs on the board and it only will be confusing to folks who might lose track of wiring. My board came with maybe a 12 inch piece of triple stranded wire. It was too short to work and too thin, and even though I tinned the strands, they weren't stiff enough to go into the connector block on the Chamberlain. I would recommend using something like telephone wire -insulated thin hard copper in insulation - and just run a wire from each of the three connections noted in the video from board directly to your garage door opener wiring connectors. I used 18 inches of wire and was able to then fold the device up above the garage door opener for storage. It also would be helpful if you want to take it down when you have to reflash the firmware when it's upgraded. I was able to keep the Chamberlain wiring in place and just slipped in another wire. I would be very careful to look at how your wires are connected before hand in case some pop out and you lose track where it goes. Also, there's no need to turn the power off although all the wiring around you can get in the way. There's no high voltage going to any of these connections. I used the HomeKit firmware 0.6 and had two issues. After I installed the software, it would not associate with the Wi-Fi and timed out multiple times as reported on other sites, In reality it does associate and if you look at your router connections , you'll see that the device does connect with an IP address to your Wifi. (curiously when I tried flashing with the MTTQ or EP house, firmware it associated with the Wi-Fi immediately)The other issue I had was after completing the installation is you have to use a QR code to install it the HomeKit Home app. The first two times I did it it establish the icon in the Home app, but it said it was "not connected" (even if the device is not connected to the chamberlain. If it properly installed You'll see both the garage door switch and its light switch.- until you see that it will not be associated from the device into your Home app - the third time it worked. Quite frankly I can't tell you what I did to make it work, but it did so be patient. 0,.6 his beta software, and one has to assume there will be issues that that have not been wrong out. Thanks again for the video -it made me think of alternative ways to do the installation that involved less steps.
