Awesome device, capable of switching 4 seperate relay channels using WiFi + the free app.
This is such a great device, and easy to set up too. It uses a free app, and the app can switch 1 to 4 relays ON or OFF, using WiFi. First of all I installed the free app, registered it, and then placed DC 5 volts into the INPUT of the 4 -channel board (using a phone charger), there was also the facility (instead) to apply from +7v to the two screw terminals on the green screw connector instead. The instructions included are excellent, showing all sorts of uses too. Once I was set up with the app, I was able to switch 1, 2, 3, or 4 on board relays to 'On' or 'Off' using WiFi from anywhere - and that is the beauty of this device - works anywhere for literally 101+ uses. I have included images of the device in use, thank you again for a most affordable and easy to set up responsive product.

Works really well and replaces the need for physical switches
Used in my car camper for operating interior lights, worked really well for what I needed, I will be working into the camper van when I get the time instillation wasn't too bad when I read the instructions properly,

Tengo muchos de estos relés instalados.Usan la app ewelink.Lo que mas me ha gustado es el rápido emparejamiento, respecto a los que mas he usado (sonoff). Un emparejamiento rápido te evita mucha perdida de tiempo y estos se ponen a buscar la red y a los pocos segundos ya están configurados cosas que con otras marcas he tenido mas problemas. Los recomiendo , muy facies de usar y programar.Ideales aperturas puertas, riegos automáticos , encendido bomba pozos , porteros automáticos...

Used this four-output smart switch for a three zone drip irrigation system. The device powered up and was recognized by the app (eWeLink) quickly, then updated the firmware in a minute or so. I used the original drip system controls 24 VAC transformer to power this device. A wide range of options are available, as you can use DC 5V, DC 7V-48V, or AC 7V-32V to power it. The outputs are dry or passive, which means there is no voltage except what you provide. So I took the same 24 VAC power transformer from the original drip control and ran it to the "C" on the relay, so that when the device responded to an on command in the app the voltage would pass through to the "NO" on the device relay and activate the water valve wired to it for the zone. The other side of the 24 VAC transformer went to the white common wire from the water valves. All worked perfectly the first time. I purchased the four-zone device, but only used three, hence the three-zone drip system. Super value for $17.99. I can't speak for the long-term reliability, as only time will tell. Key points that make it great: Excellent voltage choices, DC 5V, DC 7V-48V, or AC 7V-32V. - USB or screw down terminal for voltage input. - Dry/passive output contacts.
