Here’s a really cool feature if you live out in the sticks or don’t have broadband.
You can buy a MiFi device for approx £30 and then have complete control if you are out of range of your normal WiFi.
Perhaps you have a holiday home or cottage, you can still control your electric heating or whatever you like using MiFi & WiFi Plug. This works wherever you get a 3G signal so check your networks coverage before you buy.
