The ECO (Electricity Consumption & Occupancy) data set is a comprehensive data set for non-intrusive load monitoring and occupancy detection research. It was collected in 6 Swiss households over a period of 8 months. For each of the households, the ECO data set provides 1 Hz aggregate consumption data. Each measurement contains data on current, voltage, and phase shift for each of the three phases in the household. 1 Hz plug-level data measured from selected appliances. Occupancy information measured through a tablet computer (manual labeling) and a passive infrared sensor (in some of the households). We make the ECO data set available to the research community. The data set may be obtained from http://data-archive.ethz.ch/delivery/DeliveryManagerServlet?dps_pid=IE594964 or via its own DOI, but we always like to receive a short description of what you plan to do with the data via e-mail to Wilhelm Kleiminger.
