Abstract

Energy consumption in the residential sector represents a global average of around 30% of the total consumed in the country, so any improvement that could reduce it, would have significant effects. Some of these upgrades are the incorporation of advanced communication and control algorithms based on predictive models of household consumption. This article describes the design, development and application of a fully centralized system in which home appliances are managed by a wireless sensor network. The management algorithms are based on consumption models in combination with timing schedule, power, temperature or ambient light measurements and prioritization. On the control side, on-off management is basically presented although DALI protocol for lighting continuous regulation is now implemented too. Finally it presents future work in this field.
