Figure 2: Power demand for a typical day (Sunday 2014-12-07) in House 1.

The thin grey line shows the mains (whole-house) active power demand recorded using our sound card power meter. The stacked and filled coloured blocks show the power demand for the top five appliances (by energy consumption) and the dark blue block shows all the other submeters summed together. The thin white gap between the top of the coloured blocks and the mains plot line represents the power demand not captured by any submeter.
