So when I was on a project where the lighting system was expanded, why did everything in the Lutron system have to be replaced with new stuff? The only thing that was left were the cans and the dimming modules in them. Key pads maestros, graphic eyes, processors, etc had to all be replaced.
QS was a major architectural change for HomeWorks. Up to and including HomeWorks Illumination all devices were backwards compatible--a 20-year lifecycle and pretty impressive compared to its peers (which for many years there were none). QS can still communicate with older H48 link devices--which would include Maestros--so not sure why you had to replace those. It can now (with HWQS 8.0) communicate with all older keypad generations back to and including HomeWorks Interactive. Wiring infrastructure requirements remain the same and have not changed since 1992.
We have completed minor expansions of existing HW Illumination and Interactive systems with HWQS and RA2 by using serial communication between the two processors. This has worked well and is fairly simple to implement.
