Hopefully this is welcome news.
I have just pushed/released the next driver (0.3.0) which includes the ability to address the individual LEDs via a component. This means that functions such as Smart Lighting can be used directly manipulate the “On” or “Off” of the LED.
Because these are defined as components of the original switch, they are not directly controllable as a full-fledged device. This is similar to some of the existing Edge devices (smart power strips, secondary switch on a single device etc.). You can define a Virtual Switch and sync the status via Smart Lighting (at least using the new app).
