Smart Meter Water Consumption Measurements – Additional Evaluation Data

Data We collected the cumulative water consumption data in Germany using the commercially available smart meters Hydrus 1.3, DN 20,00 from Diehl Metering. For evaluation purpose we further collected some label data on activity events and on out-of-house periods: Activity Data: During defined time spans, we performed two typical household activities associated with water consumption and recorded the time at which they were performed. Specifically, we turned on various taps for 30 seconds and flushed the toilets. We avoided concurrent water consumption and always waited at least 5~minutes between two activities. Out-of-house Data: A separate data set is also collected in two test households. Besides the readings from the smart water meters, the absence times of the residents were also collected using the diary method. We handed the residents a log form in which they recorded those time points when no residents were in the house. The residents were also asked to note whether a washing machine or a dishwasher was running during a period of absence. Further information on data collection and description of the dataset can be found in Section 3 and Section 6 of the original article, which is available at the following DOI: TBD. Structure The Zenodo Archive has two folders, which distinguishes the two different sets of evaluation data. The Activity Data contains subfolders for each of the examined frame. Each of these subfolders contains general information about the frame (e.g., household ID), the smart meter readings (smartmeter.csv) and a list of performed activities (activities.csv). The Out-of-house Data contains two subfolders for the sampled households. These subfolders in turn contain a periods.csv file with the recorded times of presence, a smartmeter.csv file with the smart meter readings during the survey, and a general info document.
