Mobile Power Information System

Abstract

This paper investigates different methods for giving users informative feedback on their electricity consumption. After comparing different methods for giving feedback a method comparing power consumption and temperatures is chosen. The purpose is to let power consumers find out how much changes in temperatures affect their consumption. A prototype mobile application has been developed and tested on the Android platform. The application retrieves temperature values and compares this to the consumption of the users. This gives the users a heating efficiency value that describes the amount of electricity used for heating. This is presented with graphs and corresponding values to the users. The results so far are promising, and future work includes a more large scale evaluation by real users.
