About

Circadian Lighting is an integration that syncs the color temperature of lights with the sky's natural daylight cycle. Lights shift toward cooler hues around midday and warmer tints near dawn and twilight. It adds a sensor and switches to Home Assistant, and an action that updates the calculated values. Each switch can list lights to be controlled by color temperature, RGB or XY, plus lights that only get brightness changes. A Sleep mode sets lights to a dim cool white at 1% brightness. It works locally and is installed through the Marketplace (HACS on 2026.10 and older).
