Logitech Lumitra Glow and Beam Driver

Python Utility for Logitech Litra Glow and Beam

Introduction

After purchasing a Logitech Litra Glow I was unable to find any support for linux. This project reverse-engineers the basic functionality of the litra glow so that we can control it via USB without using the physical buttons on the device. It also now supports the Logitech Litra Beam.

Quick Start

Linux

# If necessary, create a udev role to grant permission to access the light
sudo tee /etc/udev/rules.d/82-litra-glow.rules <<< 'SUBSYSTEM=="usb", ATTR{idVendor}=="046d", ATTR{idProduct}=="c900",MODE="0666"'
sudo tee /etc/udev/rules.d/82-litra-beam.rules <<< 'SUBSYSTEM=="usb", ATTR{idVendor}=="046d", ATTR{idProduct}=="c901",MODE="0666"'

sudo reboot

# Uninstall if previously installed
pip uninstall litra-driver
pip install litra-driver

# Command Line Interface
lc --help

# User Interface
lcui

The UI

A basic UI can be launched to allow control of the light:

lcui

The CLI

NAME
    lc

SYNOPSIS

COMMANDS
    COMMAND is one of the following:
