WiFi Relay Switch Module Phone Remote Timer Control for Wireless Android iOS (5-32V 4-Channel)

I would pay 10x for something that actually worked perfect outside the box, from a US company and a better app/manual. But since it was under $15 I really did not mind getting more involved on the DIY side. I use this to open and close my commercial garage bay in my warehouse. Before, I had to use manual push buttons inside the door to operate. It's a 3 button system, Open (1 press opens door fully), Close (Need to press and HOLD to close), and STOP (emergency stop/used for when you don't want the door fully open). I setup relay one to click on for 1/2 second to activate the UP button. The second relay I set to inch for 18 seconds to close the door. The third relay I set to activate the STOP button- however this does not work as the STOP button seems to be wired in a different manner. I will update when I figure that out. 2 Things that I found difficult: 1- Initial connection was clunky. I do not like to allow location settings, but the app requires a precise location for initial wifi connection. After doing that I setup no problem. 2- The inching did NOT work at first. After several google searches, I found out that the "Mode" button needed to be pressed to activate this. I had to press it 2x to get the inching settings to work in the app. This I found totally pointless- why would you need me to press a physical button when the app allows you to set these times on your phone? It worked after doing this even after unplugging the unit a couple times. I was able to get this to work with Alexa no problem. So now, I can say "Hey Alexa- Open the Garage!" and my garage bay door opens right up. I have a camera facing the door just in case, and will install a wifi outlet to shut the relays off after business hours to reduce security risk. (ie, if a potential intruder shouts "Open the door" the relays would be totally powered off and would not respond). Another major plus- I have forgotten my keys before, and that means a trip home and wasted time. Now if that's the case, I can open the garage! And I can now drive my car right in to the warehouse on hot or rainy days without getting out of the car- provided I don't have too many pallets stacked up inside the door. Overall, it was a great solution to opening and closing a COMMERCIAL garage door. There are many, many ready to go options for RESIDENTIAL garage doors, but the commercial 3-button setups are sadly overlooked by most manufacturers.

My 1998 vintage gate was supposed to be controlled via landline phone system (just the wires) but the long run of wires started having issues. I already had wifi via "TP-Link power line wifi extender" for a camera at the gate. The hook-up is very simple at the gate circuit board, in fact mine already had an open/close button wired in hidden inside the cover, I just had to hook onto those wires. I only need a short "button push/inching" and it came that way but I did confirm inching is easy to change. Regarding the actual wifi connection from this module, it wasn't dead simple just a little clunky but believe me at 62yo I only have a very basic understanding of all this wifi/computer stuff and I was able to make it work.cube so my wife can easily open or close the gate from inside the house. It was also easy to make it work thru my Alexa The eWeLink isn't hard to get to work and works really well after it's running. I think (if there is not one) I will start a Facebook group so people can ask questions and give tips. For doing things like this there absolutely is nothing that can do this job at this price. If you have one already please join the Facebook group and help other out. At this cheap price I am going to order another just to play with and maybe be able to give support. Going to name the group "MHCOZY wifi Controller"

In less than one hour after unboxing, I whipped up a 3-zone sprinkler controller. Unlike another comparable product i bought a couple of days ago (and returned), the process to wirelessly discover the unit (using the eWelink) was amazingly painless. You simply plug in a Micro-USB charger, run the app, do Quick Pairing, and in practically no time you should be able to starting clicking any or all of the four relays. Since I intended to use this 4-relay system to control a 3-zone sprinkler (so I didn't need all four, maybe I'll add another zone later), I needed the relays to stay on until turned off. This is not the default behavior. Instead, when you press a button on the app corresponding to one of the four relays, it will come on and turn off almost right away. To change this, you have to press the "mode" switch (one of the settings will change the relay switch behavior t o stay on persistently). There is an "inching" behavior also, which is basically a programmable dwell time (if you need the relay to stay on a certain amount of time before turning off), which is controlled by the app. For sprinklers, the preferred method is to have a persistent "on" behavior, and then use Alexa (or other smart assistant) to control the on/off timing. One very slick feature of this unit is that you can choose to power the unit two ways. The first is to use a micro-USB. The second is to use 7-32V DC...or AC. The AC is convenient because standard electrically controlled sprinklers use a 24V AC supply. As such, you can use a single power supply to both power the relay board and to control your sprinklers. I did a quick installation, replacing the old, complicated $60 automatic sprinkler controller (which is a nightmare to program) with a single, simple Alexa-enabled controller for $20. You can simply bridge one of the AC power lines to a pin of each relay and connect the common to the other AC power line (24 V, not 115). The remain pins of each sprinkler are then connected to the remaining pin of each relay. Plugged it in, and it worked great. I was amazed at how quick this simple project came together. Integrating with Alexa took longer than the construction in the picture, but I eventually figured it out. You have to search for an Alexa skill called "eWelink Smart Home". I had a number of software crashes but eventually somehow got the device registered, and four individual devices were present in the Alexa device list. I promptly renamed three of them to "zone 1", "zone 2", and "zone 3". I then defined a few simple routines, each turning on a particular zone, waiting a fixed amount of time, then turning the zone off before advancing to the next zone, repeating the process for each zone. This is a Godsend, because I don't have to struggle with a flashlight in the garage, standing over a poorly designed gadget with small chiclet keys and a manual with tiny font print hoping I programmed it correctly. Now, you can just say "Alexa, turn on zone 1". This allows me to turn on each zone manually (with a voice command). I also programmed a pre-set number of routines to run the zones automatically through the week. Anyway, I should have waited to write this review, but was pretty thrilled to be able to knock out a simple project so quickly and effectively, and hope to inspire others to try.

I bought this relay board to open the gate at the entrance to my home by saying "Hey Alexa, Open the gate." It was not that hard to install and configure. The relay channels are backwards, the leftmost relay is number 4 not number 1, but the eWeLink app lets you operate them individually so it did not take me long to figure it out. Also, pairing it to the WIFI did not go like the instructions said. I had to reboot it a couple of times but it finally connected. Initially I installed it inside the electrical enclosure for my gate opener controller. But, when I put the cover on the metal box, the device lost WIFI. (Doh!) I ended up buying a small 4X4 plastic electrical enclosure and mounted it on the side of the gate controller box. When I first connected it to Alexa, Alexa did not understand "Open the gate" so I had to tell Alexa "Turn on the front gate." I was able to create an Alexa routine that translates "Open the gate" to "Turn on the front gate." So, now it works just like I wanted it to. I am very pleased with this device.

Quickly and easily set up to run with their app and Alexa. Able to put together routines and easily automate my projects.

If you buy this plan on paying each month to use it. I found that you cannot even set it up without paying a monthly or annual fee which automatically renews. Functionality I have no clue. I found this out when I went to set it up. I will be returning this.

Programmed using a basic micro USB charger; this was easy to do with their ewelink app. It was also easy to pair with Alexa. I cut a small opening in a plastic bandaid box and then put the board in that box and then the box in our outside gate opener. Schedule via the app works great, and the Alexa voice integration work just fine. All in all, got everything done in less than an hour with no hiccups. Home automation has come a long way since the older Insteon I/O link devices. :-)

Using this product to connect an A/C 24Vac automation valve in my pool/spa. This allow for 4 separate relays to control valve to open and close and have 2 other relays to operate pump and blower motor. They 5v input is for your board to communicate with WiFi and board operations. The relays get powered with the input power your device your trying to installs demand. This Relay will operate in AC or DC. This is a low voltage regulator for up to 32v. The web platform it uses is SonOff and is a really reliable app that can control multiple devices from Ho voltage to low voltage relays like this.

Mit diesem 4-fach Wlan-Schalter steuere ich 24-V-Ventile zur Gartenberegnung. Das Gerät befindet sich seit 2 Jahren in einer wasserdichten Installationsdose sommers wie winters draußen. Ich hatte nie Netzprobleme damit.

I was a bit concerned it wouldnt work after reading some of the reviews, however it worked fine when hooked up to DC, just ensure the polarity is correct as it likely doesnt have any protection if wired incorrectly. I tested using 12v and 24v DC and both work fine. Setup on Home Assistant via HACS Sonoff plugin, was pretty straight foward to setup. Installed the app initially to get it connected to WiFi and set a static IP in the router, the Sonoff HACS intergration pulls the local address and communications is locally rather than via the web.

Alles werkt prima. Ik weet alleen niet waarvoor ik het zal gebruiken. Gevolg van koopziek zijn.

Per quanto mi riguarda penso sia un ottimo prodotto. Ho preso il 4 canali e dopo averlo configurato e aggiornato con la sua app funziona benissimo. Lo uso sia con Alexa che con l'app proprietaria e gestisco l'illuminazione 12V in una stanza. La configurazione è relativamente semplice sia per quanto riguarda il dispositivo con la sua app sia per quanto riguarda Alexa, con Alexa bisogna installare una skill.. fatto questo si può chiedere di accendere o spegnere tutti e 4 i canali oppure uno solo (chiedi accendi canale 1 oppure nomini il canale con l'app del dispositivo con alogena, led, tapparella ecc ecc) Funziona come accendi e spegni tutti i canali Funziona come accendi un canale e spegne un canale attivo (sempre un canale acceso insomma) Funziona come input cioè attacca e stacca il canale selezionato, chiudendo il circuito di quel canale per 1 secondo. Queste funzioni le si può scegliere una alla volta e tramite pulsante. Se come me prima dell'acquisto vi state chiedendo se funziona da remoto (fuori casa, esempio in un altro paese con connessione dello smartphone 4G o wifi albergo) la risposta è sì. L'alimentazione nel mio caso viene fatta con cavo USB, prossimamente lo collegherò a una linea 12v proveniente dalle batterie del solare ... (Ho già provato e funziona benissimo.) App del dispositivo: è abbastanza ben fatta, richiede una registrazione con la vostra mail e una password (come registrarsi ad Amazon per capirci) potete mettere più dispostivi (non solo relè ma anche spine smart ecc). Accedendo con l'app al vostro relè (esempio camera da letto) potete vedere se il canale (la luce) è accesa o spenta, potete accendere e spegnere tutti i canali assieme, potete programmare accensione e spegnimento a una tot ora e tante altre funzioni e impostazioni che devo ancora capire bene. A quanto ne so tutto questo è gratuito, avete acquistato il prodotto e assieme vi viene dato questo servizio. L'app non vi chiede carte di credito ecc. Insomma, versarile, relativamente economico, funziona bene, l'app fatta abbastanza bene. Per me 5 stelle meritate, ottimo prodotto, lo riacquisteró.
