Alhamdulillah. It worked without any problem.Bought one for my friend, he plans to use it "to automate Motor Pump".Well in my case, i used it to control "VFD" connected to a 3HP submersible pump at remote location.There was a dry contact switch on the drive, i connected those connections to this switch & further connected it to a 4G Dongle.Alhamdulillah, i am able to turn the pump on/off from anywhere i want.There are other products in available online too but they are expensive.Bought this @1699

Switch works but WiFi range is very poor, hence require router next to it. No external wifi antenna option. Needs immediate improvement comparing sonoff switches.

GOOD

The media could not be loaded. Best product if want to control 4 12V devices via wifi 👌

Works flawlessly, device is configurable in smartlife app. Easy to setup and use. Bought 2 of these.

Works well

When switches ON, no output supply coming
