Current studies about electrical energy efficiency potentials bring out that to make the most part of the saving potentials achievable, a feedback about the instantaneous consumed electrical energy is necessary. More detailed, an allocation of the electrical load to the particular device can enable a greater level of sensitivity in energy consumption of electrical appliances. Therefore, we pursued the aim of developing a low cost smart meter hardware, which fits the requirements for the detection of several devices and states via disaggregation algorithms. This is implemented by applying Fast Fourier Transformation to the measured data and sending the Fourier coefficients to the appliance disaggregation modul. In this paper, we describe the developed hardware in detail and show a visualization approach of the disaggregation results for providing the user with detailed information about device states.
