We consider it as a natural thing today to be surrounded by plenty of embedded systems. Such devices appear more and more frequently in our homes as well and in several cases there is a need of automation in the entire household to make the maintenance of a building comfortable and -last but not least- economical.

The KNX system was created in 1991 to control household electrical networks. In spite of its undeniable advantages, the market share of the system is rather modest- probably due to the high cost of the building elements-, together with some other similar systems. Another barrier of their spreading more widely is that- due to the necessity of a special wiring-they are basically suitable for a new house.

Due to a continuous fall in prices of RF communication devices it became a tendency to replace copper wire control (e.g. light switches) by intelligent systems having RF interface. An important advantage of the RF-based networks is that there is very small need for modification and expertise during their installation as its wiring is not complicated. The aim of this thesis is to create an intelligent system with cheap components that makes a duplex communication possible and thus making the central processing unit capable of monitoring the operational status of the actuators.
