Circadian Lighting [Home Assistant Component]

Stay healthier and sleep better by syncing your lights with natural daylight to maintain your circadian rhythm!

Circadian Light Rhythm|690x287

Circadian Lighting slowly synchronizes your color changing lights with the regular naturally occurring color temperature of the sky throughout the day. This gives your environment a more natural feel, with cooler hues during the midday and warmer tints near twilight and dawn.

In addition, Circadian Lighting can set your lights to a nice cool 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.
