eMylo RF DC 12V 1 Channel One Relay Wireless Remote Control Light Switch Transmitter 433Mhz Remote Control Switch for Light Door Garage On/Off

These remotes work like a charm once you figure out how to connect them. The instructions were either way beyond me or just crap, but fortunately other reviewers left excellent instructions in their reviews. I’m sorry I don’t remember the reviewer’s name, but he comes up at the top of Amazon reviews for this product. My gratitude to him for figuring these out. Lastly, these have great range. They go through our exterior wall without any problems. I don’t even have to have direct line of sight. The receiver picks up the transmitter’s signal easily.

The media could not be loaded. I was using a 12V 500mAh power supply and the relay was clicking on and off, not staying on until i release the button (see the video). I thought the unit was defective, but I decided to try a 12V power supply with more current. When I switched to a 12V 1.5A power supply the momentary switch worked correctly. No where did is see required input current, only voltage. Seller might want to note this. Now working great to replace my garage door opener switch.

Comes with 2 remotes and 1 relay module.You need to get the black lid off to put wires in the screw terminals and it was very difficult for me to get it off. I ended up breaking the lid off with pliers because 1) I don’t need it and 2) I got frustrated.Once I was able to actually USE it, I had no issues. I think by default it is a toggle switch (click for on, click again for off). I did not try any programming yet.It requires plug power to work - it says 12V on the side and it does work with 12V. People said it also works with 24V but I’m not sure if they purchased a different model. This DOES work with 24V but you might just be burning it up and it might die after being left on too long. I recommend to only use the voltage that is shown on the side. I bought a 12V barrel plug which came with an adapter to easily connect wires into the relay module. It works like a charm as was SUPER easy to set up once I got that pesky lid off!

The good part was I could return them. They did not work for the application I desired which is what they were intended to do. Instructions were in broken English and the diagrams were not helpful. The interweb showed multiple people having to wire these up differently and no mater what I did they did not work.

The media could not be loaded. So I wired this to open my garage. Basically, on my garage door opener the logic board for the wireless controller seems to have broken in some way, or I was not given the correct remote. As a result, I can not pair the remote I was given, and while I'd be willing to try other remotes they literally cost more than this product.The instructions are quite clear for this product, but here is how I set it up:1. wired 12v positive to the anode, as per instructions.2. wired 12v negative to cathode, as per instructions.3. cleared codes as per step 14. held button until it did one quick flash between green and red.5. paired remotes by holding button, clicking opener button, and letting go of both. Paired one remote at a time.6. Tested relay by clicking remote. In momentary mode, you should hear the relay click when you press the remotes button and another click when you release the button.7. wired terminal 1 on garage door opener to the normally closed(NC) terminal.8. wires terminal 2 on the garage door opener to the common(COM). (Note, these wires could be flipped(1 on COM, 2 on NC) and it's fine. The goal is, these two wires must short when the button is pressed and open when the button is released).In case your garage opener is a bit different(some have more terminals), NC and COM are the two wires that go to the garage door button on the wall. For 12v power, I used an old 12v 3a power brick that went to a monitor or a laptop or something. I found it in my box of electronics cords and cables, but 12v power bricks/wall warts are pretty common and you could order one. Cut the barrel connector off and strip the wire(s) and you're in business. FYI, You probably don't need anything more than .5 amps or so, I just happened to have the 3 amp one on hand.Couple caveats:1. The momentary relay is a lot slower than a button. The consequence of this is when I stop my garage door when it is going either direction, rather than stopping it will just start going the other way. I really don't care about this lol.2. The plastic case is a pain in the a__ to separate. I ended up breaking the covers screw holes trying to separate it, which sucked. I ended up pulling it apart and effectively breaking the top part of the cover with needle noses.

I bought this to replace the remote control for my old garage door opener. It uses a push button wall switch that shorts the contacts on the side of the opener to start the motor and I bought this to connect to these contacts. This is one of the few wireless relays that I found that has the momentary closure option which is required to operate the garage door. The module does not come configured for momentary operation and you have to reprogram it. The instructions are well written-good diagrams and easy to understand. I am using a 300 milliamp power supply and that works for momentary use. The relay operates every time I push the button and so I am happy with that. A minor problem are the holes in the case that do not match up with the contacts that you connect the wires to. Easy to fix but should be right. Also, the build quality is marginal. It will be interesting to see how long this lasts. However, it did not cost very much and does the job.
