When you're ready to take your media center to the next level we have a number of options available to you. Download software like M Control or Exdomus, then purchase very affordable micro-modules that will fit behind your light switches (basic to install - 5 minutes), you'll need a CM11 computer interface module to speak to these modules direct from your media center over the powerline (no additional wiring). In an hour or two you'll be able to set scenes and control things around your house. There are more professional options like management systems that will require a bit more of your attention.
