"""Adaptive Lighting integration in Home-Assistant.
|
|
|
|
This integration calculates color temperature and brightness to synchronize
|
|
your color-changing lights with the perceived color temperature of the sky
|
|
throughout the day. This gives your environment a more natural feel, with
|
|
cooler whites during the midday and warmer tints near twilight and dawn.
|
|
|
|
Additionally, the integration sets your lights to a nice warm white at 1% in
|
|
"Sleep mode", which is far brighter than starlight but won't reset your
|
|
circadian rhythm or break down too much rhodopsin in your eyes.
|
|
|
|
Human circadian rhythms are heavily influenced by ambient light levels and
|
|
hues. Hormone production, brainwave activity, mood, and wakefulness are
|
|
just some of the cognitive functions tied to cyclical natural light.

## Notes
|
|
* Only your location is taken into account to calculate the the sun's position.
|
|
* Weather is not considered.
|
|
* The integration does not calculate a true "Blue Hour" -- it just sets the
|
|
lights to 2700K (warm white) until your hub goes into "Sleep mode".
