These devices are the backbone of any KNX installation, allowing for the connection of different lines or integrating devices via USB, IP (Ethernet), or RS232.
While KNX is the core competency, Weinzierl provides holistic system solutions by supporting a range of other open standards, including:
Weinzierl's versatile technology finds applications across various industries, including Smart Buildings, Energy Management, Industrial Manufacturing, Healthcare, Security and Environmental Monitoring. This versatility is also demonstrated by its , which enable universal integration with various building management systems (BMS). A notable showcase of its capabilities is the new Multi IO Module , a device featuring 48 freely configurable channels, each individually set as an input or output.

The history of Weinzierl Engineering GmbH is a classic German success story. Founded in 2001 by Dr. Thomas Weinzierl, the company started as a two-person operation with a single product, embodying the spirit of a small, innovative start-up.
In the rapidly evolving world of automation and smart building technology, German engineering remains a benchmark for precision, reliability, and innovation. , based in Bavaria, Germany, has positioned itself as a premier developer and manufacturer in the KNX technology landscape.
" by bridging the gap between traditional KNX bus systems and modern IP-based networks. Key Themes from Recent Reports Security Pioneers : In light of new regulations like the Cyber Resilience Act (CRA) , Weinzierl has focused heavily on KNX Data Security . They developed the first gateway on the market, the KNX ENO 636 secure , to support encrypted wireless communication with EnOcean devices Rapid Expansion These devices are the backbone of any KNX
Klaus Weinzierl, a former CERN calibration physicist turned industrial hermit, had built the company on a single, almost absurd principle: Absolute Zero Tolerance . While other firms boasted microns, Weinzierl worked in picometers. They didn’t just build sensors; they built the nerves of the world.
This commitment led them to become a platinum member of the . Over the past two decades, the company has translated complex communication standards into robust, user-friendly hardware and software tools.
Within 48 hours, the German Space Agency was in the sawmill. Within a week, every government on earth had a Weinzierl engineer on speed dial. The company, which had thrived on obscurity, was suddenly the axis upon which civilization turned. A notable showcase of its capabilities is the
Weinzierl is a strong proponent of the , the global open standard for home and building control. Their core products are designed to make KNX installations more flexible and powerful. A. KNX Interfaces and Couplers
The KNX BAOS (Building Automation Operating System) modules are the flagship products. These are tiny, DIN-rail mounted devices that connect to the KNX TP (Twisted Pair) bus and provide an IP interface.
The is arguably their most celebrated product. It turns a standard KNX installation into a programmatic powerhouse. With the ability to run custom scripts (Python/C++), the 721 allows integrators to create complex conditional logic that standard KNX devices cannot handle alone—such as astronomical clocks, weather-dependent shading, or energy management algorithms.
