I would like to build my own custom hardware to interface with the aquabus, For instance I would like to create a fan hub which can monitor the speed of all the fans individually, so I can know whenever 1 fan fails. Also I would like to control the RGB led's of all the fans individually. Other then this I have a few other ideas which I need to flesh out and see how it goes during my new build.
I've been looking at the plugin SDK, it does provide some clues as to how the bus works but nothing to add your own hardware.
