MOOD is a circadian lighting controller for Home Assistant. It automatically adjusts your lights throughout the day to match the natural rhythm of the sun — warm and dim at night, bright and cool during the day — so your home lighting works with your body, not against it. DESIGNED FOR YOUR BIOLOGY MOOD calculates sunrise, solar noon, and sunset for your exact location, then builds a smooth 24-hour lighting curve with over 280 data points. Your lights shift gradually from deep warm tones at night through golden hour warmth into bright daylight and back again. You set it once and forget it — your home follows the sun automatically. ROOM-BY-ROOM CONTROL Create light groups for every room or zone in your home. Each group can run independently in one of four modes: Circadian (follows the sun), Scene (locked to a specific mood), Manual (fixed brightness and color), or Off. Fine-tune each group with per-room time offsets so your bedroom starts dimming before your living room. SEVEN BUILT-IN SCENES Switch any room or your whole home into a purpose-built scene: Movie: Warm, low-key ambient light for watching Focus: Bright, cool light for concentration Sleep: Deep warm tones at minimal brightness Dinner: Candlelight warmth for the table Campfire: Animated flickering firelight effect Party: Cycling color palettes at adjustable speeds Wake Up: A sunrise alarm that gradually brings your lights from deep purple through coral and orange to full bright white over 5 to 45 minutes WAKE-UP ALARM Set a gentle sunrise alarm with customizable duration and repeat days. MOOD ramps your lights through a natural color journey so you wake up gradually instead of to a blaring alarm. Choose from 5 to 45 minute sequences. FULL COLOR AND WHITE SUPPORT MOOD works with both CCT (tunable white) and RGBW (full color) smart lights. Customize warm floor and cool ceiling color temperatures. In RGBW mode, dial in hue, saturation, and white blend for every scene using the quick-access tray controls. PRIVACY FIRST All data stays on your device. MOOD does not include analytics, advertising, or tracking of any kind. Your Home Assistant credentials, location data, and preferences are stored locally and never leave your phone.
