Is there a way to create additional transition periods instead of only a binary day / night?

[Kylemcarthur]

I'm a night owl with a weird schedule. I'm awake in the afternoon, then most of the night. While LightBulb is pretty fantastic, I'm running into a problem with it due to my schedule that I'm not sure how to solve.

I have the solar configuration on manual settings (8am day, 8 pm night) which feels good for my purposes. Day time brightness and temperature are default settings, and night time brings those way down to something like 90% and 2500K. I have the transition happen fairly quickly, and it occurs at the same time that I change the lighting in my home to use warmer colors. That part is great. However, I'm wanting a way to set a time for this to transition even further, down to 80% and 1900k as I get within a few hours of when I go to bed. I found I was able to set these settings by typing manually in the relevant fields instead of the sliders, so that part is solved. The schedule part is something I haven't been able to figure out.

I have considered just making the transition duration take several hours, very gradually going from default day down to my lowest setting. The issue with this is that this, AFAIK, would be a linear transition, which isn't what I'm aiming for, since most of the night I want the settings down at something like 90% 2500K, which with a linear transition curve taking hours, that wouldn't work. The possible ways to achieve this that I can see are some way to set a secondary transition (f.lux has functionality like what I'm describing for reference, which is what the picture is showing), or a way to make the transition follow a curve instead of linear. I'm also certainly open to other ideas.

Any suggestions on how I might achieve the desired effect?

It's a sine

Thanks for the clarification on that, though unfortunately I don't think that really ends up making a difference to the problem, does it? Maybe I'm missing something here.

I'm not entirely sure I understand correctly what you're looking for. If you have your solar settings set manually according to your own schedule, then your experience should also resemble what you get with f.lux, with the exception of their transition curve being more complex. With LightBulb you get the line in the red:

With transition duration, as you figure out, you can control how long it takes. And transition offset controls when it starts and ends relative to sunrise/sunset. Although that's more useful if use location-based solar settings rather than manual.

Essentially the transition resembles this graph, where 0->90 is one transition and 90->270 is the other one (with a flat line between them, for day-time and night-time).

I think essentially what you described here is what I'm trying to achieve: f.lux's more complex transition curve, if there's even a way to achieve this.

We could think of f.lux's curve as using 3 states: Day, Night 1, Night 2. Whereas LightBulb (AFAIK), uses 2 states: Day, Night.

I've kind of hacked together this in a way, where I have LightBulb toggled off for my "Day" state, then when I want "Night 1", I have a Windows Task that toggles on LightBulb, with LightBulb's Day state being configured as my "Night 1". Then LightBulb's normal features for transitioning to its Night phase becomes my "Night 2." This kind of works, but damn is it a janky work around and doesn't get transitions for Day -> Night due it being a toggle. Very open to other suggestions if there are any.
