Only after information system implementation it is possible to ensure effective and save computerisation and automation for smart house, which gives possibilities for remote devices or subsystems manage. Information system must ensure effective information collection, processing, monitoring or presentation measures. Changeable functional and information requirements are intrinsic for smart house information systems. Such a system must be flexible for new objects or systems integration. The flexible structure provides the rapid adaptation of the system to the control object directly. There was analysed smart house CIS development methods, smart house peculiarities and described systems integration problems in this job. Also presented objective model for smart house CIS and it main principals. According to analysed problems it was made model verification during experimental phase. The result - offered flexible smart house CIS model that allows save new objects implementation and olds modification.
