I'm working on a port to Go. Follow progress and try the initial version here.
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.
# 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"'
# For most operating systems, reloading udev rules is enough
sudo udevadm control --reload-rules
sudo udevadm trigger
# For others, a reboot may be required
# sudo reboot
# Uninstall if previously installed
pip uninstall litra-driver
pip install litra-driver
