The key to effective home control is how easy it is to use.  There's no easier way to control your home than with normal, conversational speech.  Once Sophie is installed in your home, you can begin controlling an unlimited number of devices with your voice.  Simply tell Sophie, "Turn on the front door lights," or establish schedules by saying "Every night at 6pm turn on the front door lights for five hours."  Talk to your home just as you talk to the people inside.
