Weinzierl Engineering GmbH

What Weinzierl Engineering GmbH does

Weinzierl Engineering GmbH is a privately held German engineering company founded in 2001 by CEO Dr.-Ing. Thomas Weinzierl and headquartered in Burgkirchen an der Alz, Bavaria. The company develops, produces, and markets software and hardware components for building system technology with a primary focus on the KNX (Konnex) open standard. Its technical coverage spans all major KNX media — Twisted Pair (TP1), Radio Frequency (KNX-RF), Ethernet (KNXnet/IP), and Powerline (PL110) — and extends via gateway products to EnOcean wireless, Modbus (RTU and TCP), and DMX512 protocols.

The product portfolio is organized across five pillars: (1) certified system software, anchored by the proprietary KNX Stack NGS with COMPACT (up to 255 group objects, 64 kB loadable memory) and PLUS (thousands of group objects, up to 1 MB) editions for TP, RF, and IP media; (2) OEM modules and BAOS modules enabling third-party manufacturers to integrate KNX into their devices, including the KNX BAOS Module 830.1 secure as the first KNX module supporting KNX Security; (3) branded KNX system devices, gateways, IO modules, and hybrid KNX RF/EnOcean push buttons; (4) software tools such as the Net'n Node bus monitor and KNX ENO Tool; and (5) professional services including hardware/firmware development, an ISO 17025-accredited KNX Testlab for certification testing, and training workshops at company headquarters. Weinzierl holds ISO 9001 quality certification, KNX Association accreditation for its test laboratory, and KNX Executive Board membership (re-elected March 2026).

Revenue is generated through hardware sales (KNX devices and modules), software licensing and royalties (KNX Stack NGS), one-time software licenses (Net'n Node, KNX ENO Tool), and professional services (development, certification testing, training). Distribution combines a global network of electrical wholesalers and specialist distributors in 30+ countries for branded devices with a direct sales motion for development-related products, OEM engagements, and technical support. Active membership in the KNX Association (including the System Group and IP Task Force), EnOcean Alliance, and Modbus Organization, combined with consistent trade show presence at Light+Building, ISE, SmartHome Expo, and regional events, supports both standards influence and global demand generation.
