## Description

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

Review: Brought new life to my old garage door opener - 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!
Review: Garage Door Opener Installation Notes - 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).

## Features

- 【Automation Security Relay】: The remote relay adopts RF technology, learning code of 433mhz wireless transmission module has high-level security for its low repetitive rate and re-learn mode,by which it can delete the old code and re-learn a new code when a remote control get lost, so you are always in control of it

### ⭐⭐⭐⭐ Out of the hundreds of relays on Amazon this is a solid choice
*by M***T on December 21, 2016*

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).
