Newgoal Smart WiFi Relay Switch - Momentary & Latching Modes, eWeLink App & Bluetooth Control, Works with Alexa & Google Home for Smart Home Automation - Perfect for DIY Home Projects, Lighting Control & IoT Devices

I bought this to test it out for a customer so he can remote reset a piece of machinery. Easy to set up, just follow the directions. No idea on durability at this point, time will tell. It also integrates with Google Home very easily.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.Item showed up without the remote, contacted Amazon and a replacement was sent immediately. Relay installs quickly, linked to smartthings easily. Worked perfect for my application and will be purchasing many more in the future.The lack of any mounting holes is a bit annoying. It is versatile and responds well to wifi and wireless commands. The Ewelink commissioning software is another matter. It is difficult to see what mode you are in 2.4g or 5g a great deal of time was wasted and resulting frustration was encountered until I got the settings rightI used this 4x WiFi switch to start my 2 computers using the MOMENTARY function via Alexa. Hooked up connections to my computers replacing system header pin connections for Power and Reset switches. Simple to do.Now, all I have to do is say: "Alexa Activate/Reset Computer One" or "Alexa Activate/Reset Computer Two" to turn on or reset my computers that are in an adjacent room.I had this installed and running in about 15 minutes.I have about 25 WiFi smart devices in my home, and from my experiance I recomend any device that supports the Tuya/SmartLife application as this device does. I say that because Tuya has reciently updated their app thats used by most Smart Home devices to support local (off the grid) integration with Home Assistant, and other Home Automation Software. Also can be flashed with Tasmota or ESP Home.Anyway (For what it's worth) here's my quick install guide.1. Use the Smart Life app (by Tuya), Not the other one2. Use one of your old Cell Phone Chargers for power (Mini USB) just plugs into the board.3. Plug the charger into the Board and yo will see the blue light immediatly, Then Press the (Relay 1) button down until the blue light flashes rapidly. It's now ready for pairing.* Assuming you have installed SmartLife on your device and already connected to your home WiFi.4. Next Hit the add (+) button on SmartLife app and just follow the prompts.5. In like 2 minutes you will be up and running.Each Relay is able to be turned on/off with the App. Also many other automation features on the SMartLife app. Choose what name you like for the 4 relays.Also Alexa will automatically pick up the device within a a couple minutes.In my case, I say "Alexa turn on (or Off) Relay 1" (or Relay 2,3, or 4), the the relay is switches on.Note by default the Relays are set to momentary, so I changed the setting in SmartLife to Stay on or Off.So to sum this review up. I got this device to experiment with some simple scripts to turn on/off not only low power (5-12 volt) and also high power 110 volt circuits with.In my opinion the Board Looks well made and solid, so I will assume it will be reliable.If I run into any problems I'll update my review.But for now A+ Rating on this device..Used one for a Wi-Fi doggy door, and another for a dog treat dispenser. Both of them operate 12v linear actuators. It took me a while to figure out the "interlock" feature, because there is just NO useable documentation, but I got them working.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!
