> [@\[OBSOLETE\] Circadian Daylight: SmartThings + Smart Bulbs](https://community.smartthings.com/t/circadian-daylight-smartthings-smart-bulbs/13623): > > Use your SmartThings Hub to sync your color changing lights with natural daylight hues [image][GitHub - claytonjn/SmartThingsPublic at Circadian-Daylight](https://github.com/claytonjn/SmartThingsPublic/tree/Circadian-Daylight) Circadian Daylight slowly synchronizes your color changing lights with local 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. In addition, Circadian Daylight 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. Circadian Daylight works better with [Hue Advanced (Connect)](https://community.smartthings.com/t/hue-advanced-connect/)! Special thanks to @juano2310 for working through some of the internal Hue code :), and… Search circadian for even more possibilities. --- _[View the full topic](https://community.smartthings.com/t/night-time-gradual-dimming-w-osram-lightify/80561)._
