The amount of wiring, equipment and work involved will depend largely upon the type of home automation system you choose, and at what stage it's installed. Hard-wired systems tend to need fewer components than the wireless X-10 types, but are also more difficult to install. Your basic system starts with a few key components. First, you'll need the transmitter/control device, which sends the signal. This could be an L-C-D touch panel, a central keypad, wireless remote, or a telephone control kit. Computer control programs are also available. Next, you'll need a receiver module, to communicate with your lamp or appliance, turning it off and on. If you have a hard-wired system, this will be done through the wiring. You may also add special X-10 switches that give you both local and remote control. From here, the possibilities are endless. You can add security devices like door sensors and motion detectors. You might want an intercom system, or whole-house audio/video. They even have gadgets for your pet, like automatic dog doors.
