This is exactly what I need.

I would vote for this - I would like to have the min/max settings behave as ceilings or floors for the brightness/colour graphs. Currently how they behave maintains the shape of the graph and just changes the Y Axis.

Someone on the forum suggested the settings 'absolute_(min/max)_(brightness/colour_temp)'

Hey guys, I understand what you want - but I don't really get why. So the transition isn't fast enough in the morning/evening?

That would be #62

Or is there something else that is the issue with the color temperature curve right now?

If I recall I wanted this to flatten the curve for colours, in order to fix the night or day colour to static, while keeping the dawn/dusk transition. If you have long nights or days it is good to have the night or day colour reached and then stay there. Currently it transitions slowly to the min/max value slowly throughout the evening or day.

So #62 might cover my wants, depending on what the conclusion was.

if calculatedBrightness < minBrightness return(minBrightness)
if calculatedBrightness > maxBrightness return(maxBrightness)
return(calculatedBrightness)

I didn't even see your pseudo code when I wrote this code to add this in:

if self.flat_limits:
    if percent * 100 > self.max_brightness:
        return self.max_brightness
    elif percent * 100 < self.min_brightness:
        return self.min_brightness
    return percent * 100

Check out the new brightness_mode feature introduced in 1.19.0: https://github.com/basnijholt/adaptive-lighting/blob/104664d3588442730f7ea9e811dd1986aca0c2e8/README.md#custom-brightness-ramps-using-brightness_mode-with-linear-and-tanh via #699

This should give you enough control to change brightness precisely.

Some more examples:
Notice the values of brightness_mode_time_light and brightness_mode_time_dark in the text box.
