Home Automation System Home Automation is a field specializing in the specific automation requirements of homes and in the application of automation techniques for the comfort and security of its residents.
The Base Station bridges the central server to the L1 node network.
It connects to the central server using USB, and then connects to the rest of the L1 nodes via Cat5 cable (RS-485 signaling) and wirelessly.

X10 is a communications "language" that allows compatible products to talk to each other using the existing electrical wiring in the home
X10 is a standard for communication among electronic devices used for home automation, also known as domotics. It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information.
