eMylo DC 12V 2CH RF Relay Smart Wireless Remote Control Light Switch Garage Door Remote Opener 433Mhz Transmitter with Relay Receiver

I have a Chamberlain garage door opener from the 1970's and the remotes were not working. About 3 years ago, I replaced the remote/receiver unit with Chamberlain's OEM model 955D. Sadly, the new unit did not work much better, so I gave up. 3 years later I tried again, but now with this eMylo unit. After some tinkering, I got it to work, and it's been flawless since. Works from at least a block away, every time on the first press. Here are some installation notes: (1) I cut the end off an old 12v DC adapter and wired it into the power port. The power light came on. (2) I put the unit in "momentary" mode by holding down the black program button as described in the instructions till the red light flashed 3 times. (3) I paired the remote to the unit following the instructions -- you will know it is paired correctly when you press either button on the remote and not only does the red light flash but you also hear an audible CLICK sound. Because the red light was illuminating when I was pressing the button, I thought it was paired but it wasn't and this took a fair amount of time to figure out. You need to hear the click sound. (4) I wired the garage door motor to NO1 and COM1. NO2 and COM2 worked, also ... I checked. (5) I extended the antennae wire to close to its full length, and was careful not to pull too hard at the connection point. I didn't see anyone else mention extending the antennae wire - not sure it matters, but couldn't hurt. (6) I used a file in a couple of places on the plastic cover, to allow more room for the power cable and antenna to come out when closed. It sounds like a lot, but if you don't hit any snags, it's a quick process. That's it. Hope you have success using this device! Now I am going to try and program the remote into my car mirror - wish me luck!

It works great, but read all of the reviews first to understand how it works and what you need to do to install it (you need to provide your own 12VDC power supply and connect it to the circuit board using screw terminals). I used an old linear adapter rated at 12V 1A. I am using it to control my garage door opener, whose wireless reception stopped working. You wire it in parallel to the wall switch. Be sure to program it to Momentary Operation using the provided instructions. Final note is that the NO1 / COM1 output are controlled by Button "B" on the remote (so presumably Relay 2 is controlled by button "A"). Also, test the remotes before adding the battery - it says there are no remote batteries included, but mine had them installed already (and they seemed new/unused).

This did come with instructions however I am under the impression that this isn't for a complete novice. I am using a HDS-TEK(TM) New DC 12V /2.0A Switching Power Supply Adapter for 110V- 240V AC 50/60hz 2.1mm with DC Connector Gift (1 in Package) by HDS-TEK to power it as it does require 12v power. I needed something with two channels because I have a motor solenoid that has a forward and reverse and this 2 channel relay can mimic a forward and reverse for a motor. This is programmable in the sense that it can be momentary, latching or interlatching via holding down the programming button. I would say the plastic housing isn't quite big enough to fit all of the wiring in it. I used a Dremel to "expand the housing" a bit. Wiring this isn't really all that difficult if you have a decent understanding of NC/NO/COM wiring. Range seems to be pretty good. I would recommend purchasing this if you are getting into relay automation. As a side note there isn't an indication of what gauge of wiring to use. I ended up using a usb cable from an old mouse (cut, strip and you'll get multiple cables haha).

I needed to start and stop a small engine on a Manlift while in the basket The original wired controls had failed. I set the unit to momentary latched mode where you press and hold a button to use that function. I wired side A to engage the starter and side B to ground the magneto. Works perfectly. I can now work from the bucket without noise, without running out of gas and without a helper to restart the lift.

Bought 2, one did not have the circuit board connected to the base inside, no screws or anything ! You'd think 50/50 but you'd be wrong ! NEITHER one bench tested with ANY FUNCTIONALITY AT ALL ! Totally worthless garbage. Made a trip to customer to install, wasted time and money way beyond cost. Brought back and tested both on bench according to instructions (which are about worthless) and no function at all on either one. The led's work as advertised, but nothing else. I returned both. Will look elsewhere.

We purchased this for our garage door as our existing remotes were becoming unreliable. This does exactly what I expected: it's connected to the physical button terminals and acts just the same. Things you'll need to know: this does not come with a power supply; we used an old 12v adapter we had in a box. The directions are ok but it's not clear on which terminals you might need if your use case is not 1 of 3 in the instructions. Once the terminals were identified, installation was pretty fast. While it's only been about 1 week, I'd recommend this device for anyone with a DIY need for a remote switch.

I wired with 24 AWG solid single strand copper for (-) jumpers. Wired for switching ground for very low amp LED 16' strip light and 10W LED flood light. Doubtful Id use it for 10A switching (+) current flow. Not enough room for stranded 16 nor 18AWG jumper wires, within case enclosure; an additional 4mm L&W needed. Excellent 30+m transmitter reception with extended antenna. Programming was the real issue. Finally found a single YouTube vid directly relevant to this 2 chnl variant.

The control fobs are excellent quality. I used this module to control some add-on running headlights of my RV. Couldn't be happier.

Llego en el tiempo establecido. Los mandos vienen con pila y son solidos, el receptor funciona bien a 20 m (estirando la antena). Yo lo utilice para la puerta de un garage y podrian mejorarse las instrucciones, pero no se puede decir que son incompletas y el aparato cumple perfectamente con lo esperado.

Acquistato per controllare un faretto led 12v 36 w montato nel fuoristrada. (non volevo smontare tutti gli interni per portare i fili fino al cruscotto, ed ho preso corrente dalle luci targa). Funziona alla grande, unica grande pecca sono le istruzioni, che (forse anche perché sono parecchio ignorante di elettronica) sono davvero poco chiare. Infatti ho dovuto cercare altre istruzioni online per riuscire a farlo funzionare. Per il resto non ho nulla da dire, forse potevano fare qualche asola in più per il passaggio dei cavi.

A l’aménagement de mon Van, en guise d’allumage de mes lampes LED, j’ai installé ce petit boîtier magique ! De l’extérieur en pleine nuit plus besoin de chercher l’interrupteur ! Bon par contre pour le branchement sur le premier schéma je regrette qu’il n’y est pas assez de descriptif...

This is an excellent choice for replacing a lost remote or broken receiver on a garage door. If the original is unavailable or too expensive, or the supposedly compatible replacement isn't so compatible,then this is for you. Fairly straightforward to fit, you can use a separate 12v power source or if the opener has one, utilise that.Simply tap in to the push button circuit , basically using the relay as a push button substitute.
