Thanks for PR and the Tasmota measure script (this will also be helpfull for others).

Could you please format the JSON? It is still valid json but not really readable because it's on one line.

Done 👍

I have checked LTC002, and I see there are some 0.1 - 0.3 measurements which are lower than standby usage. This will highly likely be inaccuracies of power meter on very low power values, which most power meters have problems with.
Did you measure standby usage or just set it to 0.4?
Also I see you "only" have 315 measurements. How long did it take to do these measurements?
Some steps in color temperature will result in a 5 watt difference (which is quite a lot). Currently the component will not interpolate, maybe I will add this in the future. So when you select for example mired 230 the component will show 20.03, when the actual value is more likely to be 18.

201,213,15.67
201,243,20.03

Above remarks are no huge deal, and I am happy to merge this at current state. But I would prefer to have a more granular CSV file (with 1000 measurements) when it does not take to much time and effort.

All values are automatically generated by the script. So yes - apparently the meter is inaccurate.

To be honest, I don't know. I didn't design the script completely, I just modified measure_kasa.py to address Tasmota_Plugs instead of TP-Link plugs. I had assumed that this script would also set the number of measurements correctly.

Okay, interpolation would be nice.

To be honest: The Hue Fair lights are permanently mounted on the ceiling. I took one down to measure this. Unfortunately, I have already mounted it again. If it can be avoided, I would like to refrain from removing the luminaire again.

This measure script measure_kasa.py was copied by another contributer from the original measure.py script, but the amount of measure points was changed (did not saw that before). Will do some restructuring on the measure scripts soon to get rid of all the duplicated code.

Yes there is already a issue for this #92, I did some work on it 2 weeks ago, but still have to finish it.

No problem we leave it this way. Will change the default measure scripts to take more measurements.

Thanks for your efforts.

I think there sholud be noted in description, that in this case LUT file contains small count of samples.

Hi @stefangries. Last days I worked on new measure script. See #141. Took the two concepts (powermeter, light controller) and made them easily interchangable. Also to get rid of all the duplicated code. So you can use the HA api to control the lights, and direct Tasmota API to get the power reading for example.
Ported your Tasmota implementation to be included in the new script, but I have no way to test it. Could you please have a look and let me know if it works correctly?
