Sonos sub mini

Measured with a Shelly Plus Plug UK on the Sub Mini's own mains lead (230 V UK), read directly every 2 s. The Powercalc Measure app (v0.7.1, Smart speaker mode) drove the sweep: pink noise streamed to the bonded Sonos Beam through its native Sonos media_player, volume 10-100 % in steps of 10, 20 s per step; the calibration keys are the Beam's volume. The app run stopped at the muted-baseline step (see #4860), so the per-step means come from the plug log aligned to the Beam's volume_level changes in Home Assistant, skipping 3 s after each change. Settings: Sub level 0, Bass 0, Treble 0, Loudness off, Night sound off, Speech enhancement on, Trueplay on; the sub was audibly reproducing bass throughout. The draw is flat at 5.8-5.9 W up to 40 % and rises steeply above 60 %, to 27.7 W at 100 %. Muted baseline: muting the Beam while a stream keeps playing leaves the sub awake at 5.74 W (90 s; 5.79 W over the app's 5 s wait + 20 s window), so 0 % maps to that. Standby: after playback stops the sub holds about 5.2 W for 1-2 minutes (60 s and 122 s in two runs), then settles at 2.85-2.91 W, in line with Sonos's published 2.86 W; standby_power is the settled value.
