licht is a command-line program (including a GTK applet) which fetches info from a local Philips Hue bridge in your network and enables you to apply basic operations, such turning lights on/off, dimming, color-temperature changing, etc.

I was looking for a lightweight program for Philips Hue, but unfortunately most don't run (stable) on Arch linux, so I decided to write it myself.

Prerequisites

This program mainly uses following python3 modules

• requests
• pyyaml
• pycairo
• PyGObject

The PyGObject dependencies additionally require some packages to be installed on your distribution. For a detailed overview see https://pygobject.readthedocs.io/en/latest/getting_started.html.

For Arch linux use:

sudo pacman -S python cairo pkgconf gobject-introspection gtk3

Install

pip install licht

For installing from source, clone the repository, and run

cd licht
python setup.py install --user

or create a virtual environment with

pipenv install
pipenv install -e .

To activate the virtual environment run

pipenv shell

or start every command with pipenv run.

Usage

To start a daemon, run licht --daemon.

usage: licht [-h] [-d] [-a] [--lights] [--groups] [--scenes] [-l <light-id>] [-g <group-id>] [-s <scene-id>]
	     [-p <subpath>] [-o {true,false,1,0,yes,no,y,n}] [-b <bri-value>] [-t <color-temp-value>] [-u <json-string>]
	     [--register] [-c <path>] [--section <section>] [--dark-icon] [--output <path>] [-v]

options:
  -h, --help            show this help message and exit

  -l <light-id>, --light <light-id>, --light-id <light-id>
			Light-id for state change
  -g <group-id>, --group <group-id>, --group-id <group-id>
			Group-id for state change
  -s <scene-id>, --scene <scene-id>, --scene-id <scene-id>
			Scene-id for state change
  -p <subpath>, --subpath <subpath>
			Subpath for state change
  -o {true,false,1,0,yes,no,y,n}, --on {true,false,1,0,yes,no,y,n}
			Toggle lights on
  -b <bri-value>, --bri <bri-value>
			Update for the brightness value [0-255]
  -t <color-temp-value>, --ct <color-temp-value>
			Update for the color temperature value [0-65535]
  -u <json-string>, --update <json-string>
			Update body for the PUT request
  --register            Authenticate licht and receive a username from bridge
  -c <path>, --config <path>
			Path to the config file
  --section <section>   Section in the yaml file to be parsed
  --dark-icon           Use a dark icon on systray (for light themes)
  --output <path>       Set the path of the output log-file
  -v, --verbose         Run program in verbose mode

Configuration

licht works with both command-line arguments as well as YAML configuration files (the first takes precedence over the latter). To set your desired defaults, edit the configuration file licht_example.yml and place it in either

• ~/.config/licht/licht.yml
• ~/.config/.licht.yml
• ~/.licht/licht.yml
• ~/.licht.yml
