The choice of methods and technologies for the interaction of home automation systems with a human based on the analysis of the specific needs, operating conditions and characteristics of technologies is proposed in paper. The analysis of existing components of a smart home as part of the entire range of Internet of Things (IoT) is performed. The possible ways of local interaction of home automation components are analyzed. The specific characteristics of different communication protocols are analyzed. The comparative analysis of the summarized parameters of local communication technologies is performed. The capabilities and features of fast prototyping modules for local interaction including optical channels are analyzed. The significance of this work is in the simplification of process of decision making during selection of communication channel and an interface for home automation systems based on the specified set of requirements including the possibility of autonomy operation when there is no Internet connection and only the powering from accumulator is available.
