HA shows 153 mired which is ~6500K as a blue color, if you look at the reference, it should be pretty white at that temperature. Am I missing something or is the HA slider just exaggerated?
I’m not using a real light, I have an MQTT “light” set up in home assistant which is really just a python client I wrote. I set the color temperature using the slider in the HA dashboard then my script converts it to RGB so I can visualize it.
In either case, the reference curves from my original post show that 153mirad/~6500k is not really blue, according to the calculation, it should be #ffdfff which is pretty white. Is the HA slider just really exaggerated?
Ah see what you mean. Yeah the light colour slider is over saturated to make the interface clearer to read. I don’t think it is meant to be an absolute reference.
This is where 6000 Kelvin sits on the slider:
In reality it should look like this (also an oversaturated image):
I just did some more digging and it’s actually an even worse story
That’s where 6000k is on your slider, which might have a different supported mired range. I’m using the mqtt light so 6500k is the (hardcoded) minimum, eg all the way left when in reality it should be almost center.
So really the proportions change per light, so rather than draw the slider correctly it is reusing a generic one, really I guess it’s meant to be more of a guide. It makes sense as a usability thing but at first I thought I had a bug in my conversations.
Since I’m writing the software for the light I’m just interpolating the hardcoded 153-500 range to whatever I feel like supporting.
