eMeter: An interactive energy monitor Markus Weiss, Dominique Guinard, Thorsten Staake, and Wolf Roediger In this work, we propose an interactive load monitoring system that provides instantaneous feedback of the energy consumption on household and device level. Therefore, we extended the capabilities of a smart electricity meter and developed a mobile phone interface that enables users to monitor, control, and interactively measure the consumption of their appliances. The system allows for identifying the biggest energy guzzlers and helps users decrease their energy consumption.
