You can probably halve all the wires snaking around your home connecting speakers, sound systems, burglar alarms and printers just by moving over to smart wireless technology. You can control all the lights in your home, check in on your home when you're away from it, turn on music and even close the curtains or blinds, for example, all from your phone or tablet. Not only will it clean up the wires, it will make your whole home function more efficiently too.
