Economic and social development and aging of the European population demands bigger requests in the comfort of living. Technological progress follows that through the development of devices and equipment implemented in new residential buildings. In present times it is possible to connect almost everything inside the house with one central control system, which will improve the safety and comfort of household members and their guests. This can range from the simplest air conditioning control to the total control over entire electrical equipment in the household. Today, smart houses can have more than one preprogramed control scenario which depends on the presence of residents in individual rooms. They “complement” residents making decisions for them using most of the today’s well-known informatic and control channels: Internet and telecommunication systems, infrared rays, all types of cables and radio frequency spectrum including Wi-Fi, with minimal electricity consumption.
