Ikea LED1923R5 "TRADFRI bulb GU10 CWS 345lm" (RGB+TW last gen)

[nepozs]

Temporary ABANDONED, due to insufficient possibility to measure using Shelly Plug S (unable to measure power <0.4W)
standby_power = 0.21W

HS mode completed, but only for purpose to find Shelly power measurement lower limit value
(generated file with unreliable values - very large count of zero values due to issue with Shelly, so I've modified script to find this limit value and pauses were set to be as fast as possible, so file will be unusable even if recovered by prediction missing values, but I'm not able to do it - missing knowledge).

Picture below shows symptoms - any value <0.4W is reported as 0W (I started modified script about 19:00):

Planned to October/November or December 2021, when I will have necessary components (new bulbs and converters GU10->E27) to measure group of bulbs, as NEW script is ready now.
