sunsetr

Automatic color temperature controller for hyprsunset.

Use

Add this line to your hyprland.conf

exec-once = sunsetr &

Alternatively, you can place and use the Systemd service and enable it:

systemctl --user enable --now sunsetr.service

Testing different temperatures

If you want to test different temperatures before setting your sunset temp in the config, I recommend using hyprsunset directly:

pkill sunsetr

then:

hyprsunset -t 4000

Config

A default config will be generated on the first run. sunsetr.toml can be found in ~/.config/hypr/sunsetr.toml

# Sunsetr configuration
sunset = "19:00:00"   # Time to transition to night mode (HH:MM:SS)
sunrise = "06:00:00"  # Time to transition to day mode (HH:MM:SS)
temp = 4000           # Color temperature after sunset (1000-6500) Kelvin

Installation

Arch Linux

AUR installation coming soon.

Build from source:

You will need to have Rust version 1.78.0 or greater installed. Clone the repo, cd into sunsetr, then:

cargo build --release

You can find the sunsetr binary in the ./target/release directory and move it to /usr/local/bin or where ever you place your custom binaries.

Dependencies

This controller has only been tested on these versions of Hyprland and hyprsunset:

• Hyprland 0.47.2
• hyprsunset v0.1.0

TODO

• Set up AUR package
• Implement gradual transitions
• Make Nix installation available
