ALEKO LM137 Universal Gate Garage Door Opener Remote Control With Transmitter HomeLink Compatible

Used this with a gate opener fob to "relay" the Homelink signal my car produces to a community gate that does not accept homelink. Since this device has relays for outputs, and the gate fob has actual "click" switches (not the little carbon pads that some remotes use), it was as simple as wiring the two together, with a tiny bit of soldering inside the gate fob.Since this takes 12V, I installed it in my car as "powered when the ignition is on".My car (Tesla Model S) can send a Homelink when ever the car nears a specific GPS coordinate... so the gate is now touch free. The car sends the Homelink, the wire hits the gate opener fob, and the gate opens.Note: The fob that comes with THIS devices is used ONLY to program the car homelink transmitter. It is not needed after that... but don't lose it, in case the car has to be reprogrammed later.

This worked perfectly for my application. Currently Tesla Model 3's do not support Sommer Direct Drive garage doors that operate at 310Mhz. I was able to install this and program my Model 3's Homelink system to operate it perfectly. On the circuit board, the inputs labeled "A" actually ended up being the "B" button on the remote, but that didn't matter. I powered it from the 24VDC output from my Sommer Garage door opener on pins 1 & 2.The range isn't great, but the range on my Sommer remotes isn't either so I can't complain there. I am concerned that since it doesn't seem to use a rolling code, that the signal isn't as secure, but that isn't a deal breaker for me. I am very happy with the application, ease of install, function and price.

I bought this widget to add remote control to one of the garage doors in my new house. The Craftsman door opener looks prehistoric, and does not have a remote. Installation was easy enough. I was able to find 26V DC power on the opener, so no external power source was required. The provided keychain remote worked well, and I proceeded to connect to the HomeLink transmitter in my car. This is where things took a bizarre turn.The transmitter seemingly learned the signal, and operated the door. I closed the cover on the LM137 and tried again... and it did not work. At the same time, the keychain remote was working fine. I tried the procedure for the "rolling" codes -- no change. Tried the "learn" button on the LM137 -- no change. When I was about to uninstall the entire thing and initiate the return, I pressed the HomeLink transmitter button for the last time -- and it worked! Closed the cover on the LM137 -- and it did not work. Opened the cover -- and it worked again. And it kept working.So there you have it. The HomeLink only works with the cover off, while the keychain remote does not care. I don't know why, but I'll take it.

Easy installation; but range is terrible. Works with the included remote from 50' away but both of my vehicles have to be very close to the inside of the gate for it to work. It doesn't work at all from outside the fence.

Use your own wire to the existing terminals pic 1, use your own 12volt DC power supply (cut off for two leads) pic 2, mount everything pic 3, plug it in and it works! Use the remote control supplied to link(HomeLink) your modern cars, we have a Buick and a Tesla. Took longer to write this review than install it. Great device!

The wiring instructions that accompany this don't match the circuit board. Instructions show A-B-C-A-B-C, while the circuit board has A-A-A-B-B-B with a few lines next to the letters that are anything but self-explanatory. I got it powered up okay, but cannot get any combination of the gate opener wires to work. The most logical configuration would seem to be the second two A's that seem to be connected by lines. But under that wiring, the gate opens automatically but won't close. And the programming instructions don't match the unit either. It says the LED light for the learn button will go on after holding down the learn button for 5 seconds or so. But the LED light is on all the time. When you hold down the learn button, the LED light will go off after 5 seconds or so, but only for a couple seconds, then it comes back on. I've tried every combination of the learn button and the transmitter button that I can think of, and nothing works.
