After installing the software, the plug has been recognized by my wifi 15s. More to press my smartphone to turn on and off the outlet. I also installed the android app on my tablet. Out of curiosity, I started the ignition and the éteignage taken outside my home with My phone connected to 3G and it worked the first blow. I had nothing to do, no port to open my box! I am very happy and I just order another one, I find it very convenient to be able control remote devices, when I'm not always home.
