WiFi Wireless Inching Relay Monentary/Self-Locking Switch Module DIY Smart Home Remote Control DC 5-32V AC90-260V Ewelink App iOS/Andriod Compatible with Alexa Echo Google Home IFTTT (DC4)

I added this relay module to my pool robot power supply. I had a spare power supply for the robot and decided I wanted the ability to turn it on/off/re-run without having to press the button on the power supply. For a very cheap price I now have the ability to start the robot from my phone anywhere (SmartLife App), ask Alexa "Turn on the pool robot", press the "A" button on the key fob, or press the original button on the power supply. I have since thought about how many other things this could be used for. The setup was simple on the app, the instructions were useless for the key fob. On the board all you need to do is hit the pairing button and the button on the key fob and it works.

I use this to control a TORK TPE24VA 24-Volt Valve Actuator Control for my koi pond. It's inexpensive and the settings using the software are easy to understand and work perfectly. Also, the "normally open" dry relays were easily able to handle the 24 volt AC power requirements of the valve actuator. Closing one relay rotates the valve to open my waterfall, and closing the other relay opens my valve for the return water which turns off the water to the waterfall and sends the return water to an alternative port in the pond. This is done by selecting the interlocking relay mode in the software.. This keeps the pump running and filtering Even when the water fall is "turned off"I can say Alexa "turn on the waterfall" or Alexa "turn on the return", and the waterfall does what it's supposed to do. How easy is that? I left it unplugged with no power for at least 2 months. When I hook it back up to a power supply again, it immediately paired and worked perfectly. It is an extremely handy gadget.

It works as advertised I guess, easy to program,link and configure, but to my knowledge you can't have any relay do a different function from the other relays, if one is set to momentary they all four are momentary, I needed a board that I could program one relay to be momentary and one relay to be on/off ect.. It would take me buying two or more boards and programming each one to a button on the remote to acheive what I wanted, so that's something for potential buyers to keep in mind, also distance is piss poor on this thing, I had to extend and raise the antenna just so it would pick up from 150' away he'll even 40' it's controlling a mightymule gate opener board, and is enclosed in a metal box, but the MM board always received from say 200 feet away, go figure, same frequency btw..I'll have to buy a single ch. Pr two xh. Board or add a delay off board to this one if I want it to do what I want. Theres my review, hope someone benifits from it,cheers

This device does exactly what I wanted: controlling an actuator with reversible polarity to move it up or down. The interlock mode is used for this (and would work for a reversible motor as well I think) and enforces that only one relay is on at a time. Another handy feature is that the board can be powered by 5v - 12v (the connector next to the USB) or by USB. So if you're using that voltage for, say, your motor you can use the same power source to run the board which conveniently avoids extra cabling. TBH I'm no electronics expert so perhaps that might cause a long-term problem but so far so good.The only reason I lowered a star for easy to use is that the documentation is slim. Basically all you have to go on is a small picture to figure out wiring. It's comprehensible but not ideal.

This has been excellent as a replacement for my old bulky irrigation system controller. It integrates seamlessly with home assistant and I have never had any connection issues in the 6 months I’ve been using it. Great value for the price

Instructions are horriblePCB has no labels to indicate which terminal is + or GndMy power supply is supplying 12v but The NO terminal seems to be limited to +5v output… my use case seems to require +12v so this doesn’t work.WiFi pairing was not possible for unknown reason.

So the instructions were great. I would love a 8 or 16 channel version of this device...First you setup an Access Point (WIFI) for 2.4 NOT 5Ghz so rename the WIFI SSID for 5G and not the same name as the 2.4. Then follow the instructions. I logged my phone onto that network when I started and if you follow the instructions with it I was able to do this in 2 minutes minus the reading of the instructions to see how to do this. Also if you long press the APP buttons you can rename the switches. Also you can name the board with a meaningful name. So I just got the other board that I ordered after the first one was ordered. This is really cool. IF you create a Smart Automation you can set it up where if you press the button on one board and then turn relays on on another board. Think of this you have outside lights front and back yards. You can set up control to switch them ALL on using multiple bards via the Smart then Automation and then pus the Plus sign go to When devie status changes select a control and then the switch position then when you turn it on or off then select run device and select the next control which switch and on or off it creates the control. Also go in to the modules and activate the offline notification to let you know if a module is not responding on the network. I set a message sms task so that when the relay is activated it sends a notice and then created another for the off condition.I am having fun with these.So either the bad reviews were a older revision of board or someone that did not follow the instructions. Wish my battery tender monitors were so easy to set up.The main key is 2.4Ghz WIFI if you try to use a dual band named SSID 2.4/5Ghz you will have issues adopting the board can not determine the difference and the WIFI will insist on being right.Home=2.4GhzEverything-else5G=5GhzThat is what you should see on your phone when you setup. Worked very fast for me.I think I want a few more of these. The buttons and the ability to add a remote set are a hug plus. The MODE switch I might remove to easy to change to modes that I do not want to use but that is my install yours may vary.I also check this and it works via cellular across the internet as advertised.Under setting, There is a power on mode when power is applied all relays turn on from a power loss. You can also turn all switches on at once. You can change the device mode there and set the momentary time. unless you set the power on setting when power is returned all relays are in the off state.I did a pretty solid check of the device.I have a project that I am working on that I will try to make a video of you wont believe it until you see it.

Estaría mejor si pudiera usar un control de RF 433

Tuya smart programı ile kullanıyorum. Sorunsuz bir şekilde çalışıyor

Über die Smart Live App sehr gut einbindbar und bedienbar und dann in IOBroaker eingebundenFunktioniert tadellos

Busqué esta tarjeta para manejar con Tuya. Y funciona sin problemas después de emparejamiento rápido y sencillo como cualquier otro articulo compatible con Tuya! Permite activar los relés en 3 modos diferentes: 1. on/off = presiona el botón en tuya y el relé se activa, presiona otra vez y el relé se desactiva2. pulso = presiona el botón en tuya y el relé se activa y se desactiva después de un tiempo ajustable (mínimo 0.5 segundos): esto sirve por ejemplo para simular presionar un botón del mando (solo se puede programar un mismo tiempo para los cuatro relés)3. interlock = solo uno de los cuatro relés se activa. Si activas otro relé, el anterior se desactiva. El relé se queda activada hasta que presiones otra vez el mismo botón.También se puede programar un tiempo. Por ejemplo 30 minutos y luego se desactiva.Se puede alimentar con un adaptador de 5V de USB o bien a través de cualquier fuente de alimentación de entre 7 a 32V AC o DC siempre que suministre más de 500mA.Muy contento con la compra!
