Measured on a Shelly Plus 1PM, one mode at a time, 30 samples per point after 120 s settling. The device has two independently switchable indicators that draw significant power: the display/button backlight (light entity with translation_key display_backlight, +0.48 W) and the air quality ring (translation_key light_brightness, +1.03 W). All base values were measured with both verified off; the surcharges are folded into the conditional branches. Note the device switches its indicators back on by itself on every mode change, so each point was re-measured until the indicator state held for the whole window. LIMITATION: the ring is the air quality indicator and changes colour, so its 1.03 W applies to the colour present during measurement (blue / good air). LIMITATION: the 'auto' preset reports no percentage and varies with air quality (observed 7.3-13.4 W over 3 min); it is deliberately not covered, so powercalc reports no value in that mode rather than a wrong one.
