Each file's second column gives information about the current device state or happened event. The file of the HiFi system, for instance, includes key-presses such as *power* or *vol\_up*. Figure 10 shows the logs for the television, the HiFi system, and the espresso machine.

**Figure 8.** The power consumption of the apartment over one full day (2nd July 2020). The power is down-sampled to one sample every 3 s. The black line indicates the power consumption recorded by the SmartMeter. The contribution of the six top-most consumers is shown as stacked colored blocks. The consumption of the remaining individually metered appliances are aggregated and shown as the blue block *Others*. A slight offset between the SmartMeter and the accumulated power of all PowerMeters can be seen.

**Figure 9.** Two days of light usage information (16th–17th June 2020). The time of day is shown on the *x*-axis while the particular light is shown on the *y*-axis. If a light was used, a black box is shown during this period. The box is filled with the set color value and dimm setting.

**Figure 10.** Three days of device logs (19th–22nd June 2020). The data of the espresso machine shows the numbers of espressos made, while the data of the HiFi system and television show key-presses on the remote. The television content is provided by a connected media PC.
