I see your point about being able to integrate a new device into an existing workflow. I certainly could build a hardware controller and did originally intend to do so but I quickly realized that whatever I built would be limited in its capabilities by its limited user interface. The beauty of a software interface is that you get to leverage off the incredible work Apple has done with hardware while freeing yourself to create a controller with nearly unlimited capabilities. Than being said, I did make a prototype box that uses the an LCD display, some knobs and buttons and works well but it would be very expensive to make in the small quantities one could expect to sell and would simply not be viable. However, there is a fellow in England who is building a hardware interface for his own LED device and we have collaborated so that his controller will work with my light box. That may be an option for some people who have existing timers they don't want to part with.
