Will submit a PR once it's ready.

This is a color temperature bulb, but it looks like the power only changes on brightness, not for a different temperature.

Measuring with a Fibaro plug, with 1 decimal accuracy.

Using 3 bulbs at once to have a more accurate measurement.

This is a color temperature bulb, but it looks like the power only changes on brightness, not for a different temperature.

It is probably problem with script or Ikea implementation, when I was checking results manually (using specialized power meter) it has showed dependency between color temperature and power draw.
I was unable to measure some models of Ikea because of the problem.

So in my opinion this PR should be blocked until extensive testing this model.

@nepozs do you have this exact model? I will also buy this IKEA model to see if I can reproduce issues with the measure script. And measure both with shelly plug S and manually with an accurate power meter to see what readings I got and if they are similar to @metbril

[metbril]

Don't wait too long with buying. The product page I referred to looks like it's out of production.

[bramstroker]

I did already order. Was out of stock in the physical stores, but could still order on the website. eta 17 december.

So in my opinion this PR should be blocked until extensive testing this model.

Have you already had a look at the actual measurements? I don't think that more extensive testing will make these more accurate. And these measurements are better than manual or lineair configuration.

My opinion and suggestion is to just merge the PR and update the measurements once someone else has done more testing. The measurements are not incorrect or wrong, just not the most accurate. And as @bramstroker already mentioned elsewhere, 1 decimal accuracy will do.

Just my 2 cents.

The lights are added to the component. See #421. Discussion can be closed.

[nepozs]

Yes, it can be closed, but only thread author @metbril or repository owner can move it to
