Stephen Raubenheimer
Co-Founder / Greentech Automation Systems


I’ve always been fascinated by systems and mechanics—seeing how individual components serve unique roles to contribute to a greater whole has intrigued me for as long as I can remember. System design intrigues me because there’s always a way to make processes more efficient, responsive, and reliable. My love for open-source software comes from its ability to empower users, giving them the freedom to meet their service needs on their own terms.

Looking back, it was almost inevitable that I’d find my way into the home automation industry. It’s the perfect field where I can apply system design techniques to practical, everyday living. Smart living, at its best, promises comfort, convenience, and peace of mind, as if your home itself were a living, adapting entity. However, I’ve often found that "smart" living today doesn’t quite live up to the idea that people are sold on. Through Greentech and the Zenith Automation Group, I’m committed to helping realize true intelligent living space, as well as homes that embody the principles of the "Open Home."

From a young age, I've been captivated by technology's boundless potential. For me, tech is the closest thing we have to magic and every day it seems to redefine what is possible. My fascination led me to pursue a Mechatronics Engineering degree, specialising in control and instrumentation, and robotics.

During my studies, I was given a taste of the emerging field of home automation. The idea of bringing the magic of technology into people's daily lives was incredibly inspiring. Yet, I quickly realised that many smart homes were falling short of their promise. In 1939 an article appeared in Popular Mechanics Magazine about “The Electric House of the Future”. The author, George H. Bucher, describes a networked house in which doors would open automatically, guests would be personally greeted by the house via an intercom, and the lighting would change according to the needs of the occupants. The average modern smart home doesn’t live up to the expectations of 85 years ago and that is why, through Greentech, I am committed to turning this vision of an intelligent home into a reality.
