Control Nanoleaf Lights on Linux Using a GNOME Extension
If so, you’re in luck as there’s a plucky little GNOME extension that lets you do exactly that.
The creator of the Nano Lights GNOME extension says their add-on “…controls Nanoleaf shapes and possibly others Nanoleaf devices on your local (wifi) network (sic)”. This includes turning devices on/off, adjusting the brightness, changing/setting the colour, and setting Scenes.
