A low-power wireless system for energy consumption analysis at mains sockets

In this article, we present a system for energy measurement at mains sockets. It consists of several smart energy measuring devices (SEMD) that use a low-power radio protocol to dynamically build and connect to a radio network to transfer power usage date to a server. At the server, the data is stored and can be accessed via web interface. Our primary goal was to build a back-end system for an energy metering platform. This platform should provide us data for a variety of services that enables consumers to understand and improve their energy consumption behavior and increase overall energy efficiency of normal households.
