Sky Sync

Innerscene SkySync is a revolutionary window-mounted light-sensing unit that captures the natural sky outside and reproduces it indoors with stunning precision. Using CIE 1931 color measurement at 1 SDCM accuracy, SkySync detects any hue or color temperature the human eye can perceive.
Continuously monitoring the sky's color and ambient lighting, it streams real-time spectral data to Innerscene's Circadian Sky and Virtual Sun systems, ensuring your interior lighting mirrors the true conditions outdoors — from bright midday sun to subtle twilight tones.
With SkySync, every space stays in rhythm with nature's light.
