This paper introduces the concept of Smart Home, its components and applications in terms of saving and energy management, describing the characteristics and the operation of the sub-metering by circuit and the intelligent power switch, as well as its integration with the smart home. In addition to that, the regulation and Colombian legislation that promotes the rational and efficient use of energy, the use of non-conventional sources of electricity and the first steps towards the implementation of smart grids in Colombia, are exposed. This research presents the topology and the implementation of a residential distribution system, which allows controlling the energy flow through different energy sources and housing loads. Finally, the behavior of voltage in the loads in different connection scenarios is analyzed, stressing the importance of the appropriate realization of commutations at the IPS.&nbsp
