Twilight for Home Assistant: intelligent, solar-aware lighting automation. Solar-aligned time slots per area, multi-channel scheduling, motion/input-driven activities, scene & script execution, built-in analytics and a full web UI.

Circadian Rhythm Lighting Integration for Home Assistant

Home Assistant blueprint: three-phase circadian lighting — full white by day, warmest Kelvin after sunset, then true RGB red until dawn. For lights that support both colour temperature and colour.

Control Nanoleaf lights from the command line or a web dashboard, with a weather-aware sunlight simulator that mimics natural window light throughout the day.

Hue lighting as code: declarative bridge config + a resident circadian daemon

STM32G4 firmware powering ARC Lamp — intelligent, high-output LED lighting for people, plants and education, featuring real-time control, thermal management and safety.

Home Assistant integration that drives lights along a 24-hour colour and brightness curve, applying the colour in the same command that turns the light on

Hub-free circadian tunable-white lighting on a single Shelly Plus RGBW PM — pure on-device mJS

Open-source circadian lighting for Control4: a multi-instance controller and a touch-panel/app webview that drive brightness and colour temperature of tunable-white Light V2 lights along a 24 h curve. Astronomical switchpoints, manual-override aware, no cloud.
