Wire control for garage door

[Mesozoic]

Just curious if anyone has experience with adding a wired control for garage door openers. I have 2 older garage doors that I've retrofitted with Ryobi GDOs (belt driven, Wifi and RF operated) and they both have a rubbish RF indoor keypad with terrible range. These keypads are also non-backlit and require AA batteries, so not the most desirable setup. The Ryobi units I have installed have 2 terminals for keypad wiring on them labeled 'R' and 'W', presumably for wires of the typical red and white color? I tried to connect these to a standard Chamberlain wired control and it did not work. I wonder if the Ryobi units use a different communication protocol or something.

Any help appreciated!

Some of the older units just used a standard spst pushbutton switch. Try jumping the terminals.

Bingo. I'd swap some for most.

I got rid of the Ryobi GDO's for a variety of reasons with this being one of them. Because those Ryobi keypads do a couple things depending on how you push the button, a normal door bell button will not work. There is some circuitry in the button that causes a pulse width that the opener itself is looking for.

You can work the door opener off a wired button, however you need the Ryobi brand wired door button from the original or early revision of the opener (pre-lawsuit with Chamberlain). You might be able to find the button only at Depot. I had an early Ryobi GDO unit and had trouble with it. Ryobi replaced the motor unit with a newer revision via warranty. This is how I know both units and how they work. Ultimately I sold both openers on FB marketplace and bought a Chamberlain. Was tired of the Ryobi opener that worked, but only kind of, and not as well as you think it should.

Thank you! This is what I suspected. My next step was to put an oscilloscope on the signal coming out from the wireless receiver that is wired to the GDO to characterize it. With that information I'd be able to program a small microcontroller to match that signal output and wire a GPIO pin to a simple push button on the wall.

It sounds like a PITA, for sure. I've got a Liftmaster direct drive on my 3rd garage door, but 2 of these GDO units on the others.
