Before KNX Virtual and KNX Simulators, if you wanted to be the best, train, or do a demo for an important client, you had to build your own demo corner inside your office. This was very limiting, as you needed the client to be physically present in the office for the demo. That’s why I started creating portable demo cases for myself, my previous employer, and some paying friends. In one particular situation, I even built a demo case simulating a full hotel room (the one with the round LEDs around the center). Time has passed, but I still remember that just because something doesn’t exist doesn’t mean it can’t be built. Only God can help with the impossible; for the possible, I can help.
