*light*\_\_<*room*>\_\_<*deviceName*>\_\_<*deviceModel*<sup>&</sup>gt;*.csv*

*room* is the room the light is installed in, *deviceName* represents how this light is used (e.g., ceiling light) and *deviceModel* matches the light model name. The file's second column represents the state of the light (*on* or *off*), the third column is the light's intensity (0 % to 100 %) while the last column represents the light's *hex* color. If setting different colors is not supported by the light, the column only shows *None* values.

As individual measurements of the apartment's lighting have shown, the installed smart lights consume constant apparent power linearly increasing with the light's intensity (dimm setting). As information of the lights' state and dimm setting is available for the complete recording duration, this information can be used to estimate the power consumption of each light.

The smart light logs of two days are shown in Figure 9. The *hallway ceiling light* consists of three light bulbs and is triggered by a passive infrared sensor. Hence, all three light bulbs are turned on if a resident walks through the hallway, which can be seen in Figure 9 throughout the days.
