Sadly, for the time being, libratbag cannot control the RGB zones individually, nor enable the rainbow wave animation.
it's very cool and pretty, but not very useful
On Windows, the G Hub software enables some integrations with games. But when you play a game, your hand is on the mouse, so you cannot see the LEDs !
Libratbag provides an Python API as well as a command-line interface, so I can program whatever color, animation (pulse, solid) and brightness I want.
I decided to use the RGB LEDs as a battery indicator:
- fast-pulsing red for
- fast-pulsing orange for
- slow-pulsing green for discharging
- slow-pulsing blue for charging
I can get the battery status through the
psutil Python package.
I also added another feature: a fast-pulsing bright white whenever a notification comes up.
The D-Bus API allows you to not only listen for incoming notifications, but also to listen for the dismissal event. So the notification indicator won't be a dumb timer, but will correctly react to the desktop state.
I didn't implement a timeout for the notification indicator, because my GNOME desktop automatically dimisses notifications (they remain in the notification history).

Conclusion & disclaimers
This script has only been tested on Ubuntu 20.04 LTS, with the Ubuntu GNOME desktop, and with my Logitech G203 LightSync.
If you have RGB mouse that has multiple LEDs, this script will only use the first one. You can modify the function
set_rgb to use multiple LEDs.
You could even use each LED for a separate indicator, the possibilities are endless !
