Introduction

Sunsetr is an automatic blue-light filter for Wayland compositors. It automates smooth color-temperature transitions from neutral to warmer tones, designed to reduce eye strain and improve sleep. Sunsetr automatically adjusts your displays based on your geolocation or manual time settings. It can also be used to persist the same color-temperature and gamma indefinitely, and can alternate between various user-defined presets. The controller can integrate with and automate changes in your shell or UI applications via IPC.

Getting Started

To get started, continue to the Installation guide, then follow the Quick Start guide to set up sunsetr with your compositor.
