eMylo Smart WiFi Light Switch Wireless Relay Switch Module Remote Control Home Automation Timers Compatible with Alexa Echo Google Home iPhone Android App 2 Packs

Nice product. Instructions are clear and the item itself can be integrated easily. The working principle is also described very well.

Straight forward wiring, and easy to connect to phone, and home network, however, this model will not fit in a standard single gang box, and is an extremely tight fit even in a 4 gang box. If you understand its limitations, than this is a fine product,, but it is absolutely unusable for some applications

Cutting wire to install this device was weird. Wanted to use it on wall mounted switch but did not work. Trying to repurpose the devices.

To start with they are current rated so they have limits. These work fine if you completely replace a switch. The overall construction of these is cheaply made. One of the four pack I received the end cover was broken off. Wires are real short and the provided connectors in my opinion are junk. Might work nice on stranded 14 but what house wire is like that. The size will fit in electrical box but as stated replacing a switch and blank cover. What I hated the most about these is unlike smart bulbs they do not stay in last state / position. As a comparison you can use a smart bulb and still operate with a light switch. So during the day you can enter / leave a room and operate the lights on a switch. When you go away you can leave switch on and operate through smart life app. With these relays they will remain on Wi-Fi in app as the lights do. However you have to leave switch on and only operates on Wi-Fi. It will not hold the state it was in. It is literally a switch. Not very useful in comparison to bulbs. So really depends on what you want to achieve. This is not for some home do it yourself. Make no mistake this is electrical and should as a minimum be done by someone with that expertise.

Once I actually followed the directions to the T. it works like a charm. You have to make sure you are using the 2.4GHZ setting on the modem and it works perfectly. Initially it was attempting to connect to a 5.0 GHZ signal and it failed every time. Has been working daily now with no issues for over a month now!!

So I had tried several other products, such as the popular Sonoff brand switches. I absolutely could not get them to work at all, even after contacting their support. I ended up returning those other brand switches. So I ordered these on a whim, they are a new product, and when I ordered there were NO reviews posted yet. Risky I thought, but oh well. Upon receipt they were nicely packed, with good quality quick connectors instead of crappy wire nuts but - first complaint here is that while the end caps are removable, there is no point to removing them. The wires are soldered to the PCB inside the unit - personally, I would rather them forgo the quick connects and wires, and just put a screw header on the PCB for connecting whichever wiring you need to. Nonetheless, the ends of the wires were pre-tinned with solder to keep them from fraying which was a nice touch, and the connectors they provided were of good quality - but they dont work well on high AWG wire (such as 12 AWG). They did work good on smaller AWG however. In my use case, I was putting these switches inside of fluorescent fixtures, where the internal wiring is 18 AWG, but the home wiring is 12 AWG. So I was able to use the connectors for the fixture side of the switch, but not for the internal house side. It would not bite onto a solid core 12 AWG wire and stay attached. Just something to note if you are using these as most people would. Anyways, those issues aside, they were fairly easy to set up - I used some double-sided foam tape to attach them to the inside of the fixtures, and was able to get them wired up fairly quickly. You could do this and then set them up in-situ, but I decided to get them setup prior to wiring, and I am glad I did. Thankfully I have a quick-test so I can connect devices to mains for situations like this (search for CLIFF Quick Test on Google, I cant recall where I ordered my US version from). This enabled me to connect to mains voltage at my workbench and get them configured and synced to my account prior to installation - definitely do this if you can. As for setup and linking: The instructions are pure garbage. Throw them away and do this - this was the ONLY reliable method I found to configure. 0) Before starting, you absolutely positively you must have a 2.4 GHz only wireless AP set-up. I did this on my router by setting up a guest network for all of my smart devices on the 2.4 GHz band only. This ensures the device only connects to that SSID and that frequency, and wont complain in the app if you have a dual band router. 1) Connect your cell phone to the same 2.4 GHz AP you are using for the smart devices. Install the Smart Home app if you have not already and get your account set up. 2) In the app, use wall switch for adding a new device type, and get it to the point where it says to make sure your device is blinking during the on screen setup. 3) Hold the button down for at least 10 seconds. It will click several times. After 10 seconds, release the button. 4) Immediately after release, count for 1 beat, and then hold in the button again for an additional 10 seconds. 5) Click the confirm/next button in the app to tell it your device is blinking. 6) Wait for the phone to finish setup - the switch might click once or twice. Be patient! Sometimes it takes the full 2 minutes. 6b) If somehow this doesnt work, return to step 3 and repeat, making sure you are following the button holds exactly. 7) It should be set up - test and make sure the switch clicks when you press the switch on screen on the app. Rename the device as desired - it will probably come up named by default with chinese characters. 8 - optional) Link your smart life account with your google or amazon account according to those providers normal process. I did this with google - and then afterwords I told google home to resync devices. Congrats, done! Now install them in the fixture (turn off your power at your breaker panel first!!!) and restore power, and give them about 30 seconds or so to reconnect up, and then test them out. Note: you could do the setup in-situ if you cannot connect before installing, its just going to be more difficult if you are on a ladder arms above head :) Oh and last bit - once all of this was done, they are working GREAT - they respond extremely fast - I also inspected the components, and they used decent quality components - the relays seem properly sized for the task, etc. Just make sure you adhere to their specifications - 10 A MAX - I wouldnt go more than 8 amps to give yourself a buffer - I am using on lights, so probably an amp max for me. 4/5 stars due to poor instructions and other minor complaints. If they update the instructions and change to screw post connectors, I could give this 5 stars.

Bought the switch for a ceiling fan. Before I installed it all the way, I just dangled the switch off the proper wires. I downloaded the app for it, Smart Life. Tried one, then the other switch (At one point I had the output routed to the input and I thought maybe I blew the switch). Neither one could be recognised. I read the review saying to trash the directions, instead press front button for 10 seconds, release for 1 beat and repress for 5 more seconds to get it to work. We were on the same 2.4 gz. network, tried on my Android and wifes Iphone. Two DAYS we tried; we got fast blinks, slow green blinks, red and green blinking, red steady light, etc. You name it, we experienced it. The TWO sections of a total of 140 words that tell you how to get the software installed is about the WORST set of directions, EVER. Got nowhere. Then I read the review that said to download the TuyaSmart app. It is, basically, THE SAME APP! Except this one worked in like 5 seconds. Seriously, after all the hassles I thought, Well, this bombed on me too only to be astonished it said that it had worked and accepted the switch. Then we took the working switch temporarily down as we had to wire the fan up. In the course of events, I mixed up the switch I KNEW worked with one not yet installed. I wasnt positive they were swapped, mind you, so we proceeded anyway. Guess what? It was NOT the first switch. The other switch set up in like 4 seconds though! It works like a charm. The signal penetrates even under the canopy (which was a squeeze, but there was enough room). We got it up, my phone switched on fan, previously configured smart bulbs on the fans light kit turned on as when we asked them to. Then they turned off. . But, when the fan stopped via the wi-fi switch, I realized that to get the switch on again for the LIGHTS to be able to work, I would also end up turning the fan back on. My goal was to make both the fan and the light work via voice control (or phone!) A rather simple fix, I will just rewire the fans lights to they can come on when the switch is on via voice by bypassing the wi-fi switch and just allow the switch to work the fan. Under this scenario the wall switch stays on all the time. The lights have their own built in Alexa switch! Home automation IS NOT easy, but it is challenging and with each new device wired for voice, I get a little closer to my goal of 100% automation.

It works as expected. if you have it in line with another wifi set of lights it will independently turned on.

Works flawlessly! Installed in the metal breaker box to turn my pool light on/off with Alexa. No issues connecting to WiFi and uses the Smart Life app I use for numerous other devices around the house. Recommended!

Actually I was looking for smart switch for room light. But my friend who has old style load cable alone behind the on/off switch.So, I just decided wifi switch we can install at behind the light.I found out eMylo Smart wireless wifi switch and some wifi switch. But eMylo used Smart Life Application and also support Amazon Alexa and google assistant. So, I just choose eMylo for who has already used Smart Life App. Installation is really easy and fast because of socket connector. That connector is really easy and safe to use if you know how to do exactly with this connector. After installation, Smart Life App setup is charm. My friend can use his room light on/off at his cell phone or voice. His old style switch need to turn on all the time. I just turn off manual switch and turn back on the switch and check the wifi connection. This device connect the wifi right away and ready to use. So far so good, this device is pretty great until now.
