Monitor one - User LED

I would like to use one of the user LEDs to indicate some statuses of the monitor one. I am a little l lost where to start. Can someone point me in the right direction.

I see from the documentation it is an I2C device and I've pulled up some documentation on the ADP8866 I2C LED controller and thought I might be able to use a generic library for this but the one I've briefly used is wire which (Arduino) but it doesn't seem available.

It's built into the Monitor Edge software. The API is here.

rickkas7, thanks for this it got me moving forward.
