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 a clock-based schedule. 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.

## Features

- **Multi-Compositor Support**: Works with Hyprland, Niri, Sway, River, Wayfire, and other Wayland compositors
- **Native Hyprland CTM Backend**: Direct Color Transformation Matrix support for Hyprland
- **Smarter hyprsunset Management**: Add longer, cleaner, and more precise sunset/sunrise transitions to hyprsunset (Hyprland)
- **Smooth Transitions**: Configurable fade effects with adaptive algorithm
- **Preset Management**: Quick switching between configuration profiles (e.g., day, gaming, weekend)
- **Hot Reloading**: Live updates when config files change
- **IPC for Automation**: Unix socket-based IPC for scripting and external integrations
- **Geolocation-based Transitions**: Automatic sunrise/sunset calculation based on your location
- **Interactive City Selection**: Choose from 10,000+ cities worldwide for precise coordinates
- **Automatic Timezone Detection**: Falls back to system timezone for location approximation
- **Universal Wayland Support**: Direct protocol communication on Wayland compositors
- **Smart Defaults**: Works beautifully out-of-the-box with carefully tuned settings
- **Flexible Configuration**: Extensive customization options for power users
