Philips AC0951_13

Measured on a Shelly Plug S (first generation, model SHPLG-S) with the Powercalc measure tool. Four 60 s average sessions at fan speed 33/66/100 % plus standby, and two recordings (868 and 558 samples). Preset values come from transition-free plateaus of at least 30 s; where a plateau exceeded 900 s it is preferred over the 60 s session, because a one-minute window cannot rule out that the fan was still settling - turbo measured 20.02 W over 1001 s versus 20.41 W over 60 s. The display backlight is not modelled as a separate branch: it is a plain brightness light without its own switch, and its share overlaps the sample scatter, so it cannot be separated reliably from the fan load. LIMITATION: the 'auto' preset is deliberately not modelled. The integration derives the fan 'percentage' attribute only from the fixed sleep/medium/turbo patterns, so auto mode reports no percentage at all - there is no reading to map. Assigning a value there would be a guess, so powercalc reports no value in that mode instead of standby power. LIMITATION: manual fan speed without a preset reports no percentage in this integration, so the fallback calibration only covers the measured 0/33/66/100 % points.
