The Internet of Things market is experiencing a period of intense growth. From 7 to 10 billion of connected devices in 2013, it is expected to reach 26 to 30 billion in 2020. Smart buildings represent between 2 to 21% of this market. Indeed, the possibility of connecting objects changes the paradigms of measurement, monitoring and management within the building. This paper presents a miniaturized event-driven low power electronics device dedicated to electrical loads in the context of energy management and optimization systems. An electronic device for distributed intelligence is proposed. It is designed and intended to be added in the path of the power supply of existing electrical appliances. This device helps, as well, to perform local processing of measured data in order to provide a dedicated and optimized control of the connected load.
