This is a downstream fork of stefanwichmann/kelvin with the sole purpose of overriding the sunrise/set logic. The upstream's philosophy is to coordinate the light schedule based on sun position (some background can be found in this issue), where I prefer to keep a constant circadian light schedule based on my wake and sleep times, regardless of season.
A simple, lazy modification accomplishes this: the astrotime module that would normally calculate sunrise/set times is removed, and the calculateSunrise and calculateSunset functions always return 11:00 and 13:00 respectively. Now, the defaultColorTemperature and defaultBrightness configuration will only be active during that midday timespan, and the rest of the day can be freely customized using beforeSunrise and afterSunset schedules as normal.
Hue default scene values, found from reddit:
Assuming you're talking about the gen 3 A19 white and color ambiance bulb:
Relax 2237 ~200* Read 2890 ~570 Concentrate 4291 ~800 Energize 6410 ~550*The Relax scene is 56% brightness. Lumens calculated by multiplying brightness at 2000K (342 lm) by 0.56.
And then for the gen 3 A19 white only bulb:
Scene Color temp (K) Brightness (lumens) Bright 2700 840 Dimmed 2700 ~252** Nightlight 2700 ~84*****Dimmed is 30% brightness. Lumens calculated by this formula: 840 x 0.30
***Nightlight is 1% brightness, but there is no difference in brightness below 10%. Lumens calculated by this formula: 840 x 0.10
