10-SE, thanks! I happened across this thread while trying to figure out why moving two wires from a MyQ wall switch to VCRX resulted in nothing happening at the opener. Rather than wire up a bunch of wall switches, I went with your solution and used a Liftmaster remote, because you can get them with three discrete buttons, they're much smaller than a single wall controller, and it means one VCRX with one small device next to it, can control up to three doors. I've never soldered in my life but it was fairly easy to get the job done. I just had to use a multi-meter to figure out which solder points around the contact switches went to 0 ohm when the button was pressed, and then soldered the leads to those. I also soldered in +/- leads to the battery contact points and have the remote powered by the same Lutron power brick as the VCRX (with a 5vdc buck; see below), so the remote will never need a battery or battery change. VCRX and the remote are hidden in a wall enclosure near the doors since contact switches are also wired in.[pre].[/pre]FYI for anyone wanting to try this and powering via the Lutron power bricks / wall warts, model T120-DC9, seems to output a ridiculously different voltage than what is stated on the label. I tried three different units I had handy and all three are in the 14.4vdc range, nowhere close to 9v. The table top keypads, main repeater, aux repeaters, etc. all use these, and all seem to tolerate the 14.4v input. The garage remote I was about to power from it uses a pair of batteries to run at 6vdc though, so I was concerned I might fry something if I put 240% of the proper voltage in. I found a twelve pack of DC buck converters on amazon for $1/ea, which drop up to 24vdc down to a configurable output; I went with 5vdc which the remote seemed fine with. https://amzn.to/3n8Hc0A You can wire two contact switches into the VCRX, so you can add two floor mount contact switches to two doors, and connect to inputs 1 and 2 on the VCRX. Depending on how you want things to be triggered, just get contact switches that have three wires so you can choose between NC/NO by using the right wires. Garage wall controls themselves are pretty ugly. Using VCRX+garage remote hack, and hiding them away, you can instead use a keypad, wall mount tabletop, or even a pico to be the garage door switch. You don't use the battery, you power it.
