TIME_RATIO = 13 isn't exact 1 second unfortunately, seems not possible, measured: 5000 is 375ms == 13.3 7000 is 550ms == 12.7 9000 is 700ms == 12.85 12000 is 925ms == 12.97 16000 is 1270ms == 12.6 25000 is 1970ms == 12.7 26000 is 2040ms == 12.75 ratio or maybe even 13 (10x was 20 seconds)
Trying measuring the other way: 13.11 too slow 13.02 too slow 12.9 too fast 12.97 too fast 12.99 too fast

there's 8 scenes to upload to device (or maybe that's just stored in the app?) looks like whole light is 26 chars, e.g. white: '28280100000000000003e803e8' every color in a scene finishes with '03e803e800000000' of this, first 2 is saturation next 2 is unknown next 3 e.g. '1f4' is brightness 2 chars before, unknown 8 chars before, e.g. '46460100', prefixes every one out of these, first six tell us about speed, e.g. '4646' or '6282' max speed? next one is '0' next two are either '00' or '10' last 2 (or three?) are hue and at the very beginning of scenes, 2 digits, e.g. '06', '05' -- hmm?
