I ve heard of “power line carrier device” but I m not sure what it is. What is it?
Power line carrier device is a technology for controlling light switches and wall outlets in your house. By replacing your existing switches and/or wall outlets with power line carrier devices you can use existing wiring in your home to control the new switches and wall outlets. Your main computer can transmit a signal, over the existing wires, to the switch or outlet to turn lights and outlets on or off and to brighten or dim lights. The new switches can also be controlled manually at the switch.
