The term domotics indicates “building automation”, that is the system used to control all services in a building, designed to improve comfort, safety and energy savings in the latest generation buildings. Whether directly or through the use of remote controllers, smartphones and tablets, it can be used to control lighting, heating, video surveillance and many other household electrical devices as long as they meet the compatibility requirements and are adequately interfaced. While performing the same functions, each domotic system differs in terms of the protocols and signals used to enable inter-unit communication.
