Since no solutions have been proposed in Colombia that seek to reduce the
consumption of electricity at the residential level, this paper describes the
design and implementation of a simple prototype of a low-cost home energy
management system (HEMS). The objective of this plat-form is to monitor the
energy consumption of typical household devices so that users can access the
consumption of each device separately and then establish the strategy that
allows them to reduce energy consumption at home. In order to demonstrate that
our system is viable, the system has been evaluated by measuring weekly energy
consumption with the on-line and off-line HEMS using a test bench with typical
household devices in a Sincelejo typical household. The evaluation has shown
that with the installation of this HEMS, consumption is reduced by 27%. This
shows that it is possible to achieve a good reduction percentage with a
low-cost system.
