Change a hue light's color based on air quality data from purple air.
cargo install purple-hue
purple-hue is in the AUR.
In order to run purple-hue, you need to configure a sensor, light and register a user.
You can find the sensor id from the purple air map. The light id is available through these instructions. Finally, you can register a user via purple-hue register-user. Save all of these in a purple-hue.toml file either at /etc/purple-hue.toml, ./purple-hue.toml or $XDG_CONFIG/purple-hue.toml. An example configuration follows.
light_id = 1
sensor_id = 1
user_id = "user-id"
This repository has a systemd unit and timer that can be used to run this as a systemd service every minute.
