as title

made a quick and dirty measurement (with a z-wave Greenwave single socket plug) based on the most costly color:

            - entity_id: light.led_strip
              standby_power: 0.1
              linear:
                attribute: brightness
                calibrate:
                  - 3 -> 0.4
                  - 38 -> 0.5
                  - 51 -> 0.6
                  - 64 -> 0.8
                  - 89 -> 0.9
                  - 102 -> 1.1
                  - 128 -> 1.4
                  - 140 -> 1.6
                  - 153 -> 1.9
                  - 166 -> 2.2
                  - 179 -> 2.4
                  - 191 -> 2.8
                  - 204 -> 3.3
                  - 217 -> 3.7
                  - 230 -> 4.3
                  - 242 -> 4.8
                  - 255 -> 5.7

and which made me wish for a straightforward way to calibrate based on brightness %, which is what the HA frontend shows..

ofc this is not a true attribute, and we can template it in the dev tools:

still, it is another step complicating things...o well
or attributes column:

got it working for now:

Nice @Mariusthvdb. Cool frontend card btw.

You should really have a look at the measure tool. It's plug and play. It will fully automate the process of measurements, and will also walk all the colors.
Shouldn't take more than 2 hours to complete.
No need to take manual measures and it will be more precise as it takes hundreds of measure points.

Here are the instructions: https://docs.powercalc.nl/contributing/measure/

Another plus is I can also accept those measurements to adopt into the library and you help others that way having this same light.

Could be your smart plug does not report new values often enough, or does not report a value at all when the power of the light does not change a significant amount.
Have a look at MAX_NUDGES setting in .env, than you can force a significant change in the brightness of the light.

yes I've edited that a bit and pre filled those fields.
also changed the metering device to a listed Shelly Plug

# Predefine answers to questions
# COLOR_MODE=hs, color_temp <----- what should this be?
GENERATE_MODEL_JSON=true
GZIP=true
MULTIPLE_LIGHTS=false
LIGHT_ENTITY_ID=light.led_strip
MEASURE_DEVICE=Shelly Plug S
NUM_LIGHTS=1
LIGHT_MODEL_ID=ORMANAS LED Strip
# MODEL_NAME=xx
DUMMY_LOAD=false <---- not sure about this
POWERMETER_ENTITY_ID=sensor.tester_actueel
# RESUME=true

it chokes on my:

COLOR_MODE=hs + color_temp

or with a comma separation though, so I've left that commented and selected it in the script for now.

what is the correct syntax there? so I dont have to keep selecting that.

10 hrs go......

btw, what is that Dummy load? what should I do with that

well its been a fight so far.... the very low brightnesses on most colors didnt trigger the power meter to change value, so it kept aborting.
Ive added a dummy load of 0.1 ( I did measure that before, so seems reasonable) and added the auto HA update.
And restarted again. and again.
It seems to be doing ok now.
get the feeling the Shelly is less responsive than the Greenwave originally wanted to use, maybe Ill redo the measurement when the current one has finished.

In 9.3 hours ;-)

that is to say....
:
raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))

could it be that the Mac in power saving mode causes that?

o well, I give up, it keeps disconnecting, this is not doable as it stands.
ive tried 3 different meters (Greenwave, Fibaro, Shelly) and no luck so far

ehhh, I didnt give up...
and, after going back to the Fibaro and measuring above bri=36, it hasn't disconnected anymore.
currently at bri=117 and still 6.9h to go, there finally seems to be real progress

well what do you think... Docker script finished
hs.csv.gz
color_temp.csv
color_temp.csv.gz
model.json
hs.csv

now let me see if I can upload those to your repo
