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.
Their solution allows engineers to simulate a physical building’s logic entirely in a virtual container. You can stress-test a skyscraper’s energy logic on a laptop during a train ride to Munich, then push that config to the physical hardware on site. This "shift-left" testing reduces commissioning time on construction sites by weeks.
To make work easier for planners and system integrators, Weinzierl offers an ETS App that is available free of charge in the KNX Online Shop. Additionally, the ETS App "Weinzierl Diagnostic" is available, which can be used to conveniently set up and monitor diagnostics.
is a premium German developer and manufacturer of high-end software and hardware components for intelligent home and building automation. Founded in 2001 by CEO Dr.-Ing. Thomas Weinzierl, the company has grown from a two-person operation into an industry leader. It serves as a major backbone for the worldwide smart building market.
A line of compact, DIN-rail mounted I/O modules with an integrated web interface. Unlike competitors, Weinzierl prioritizes electrical isolation and thermal management in high-density switch cabinets. They over-engineer the power supply sections—a classic German engineering trait. weinzierl engineering gmbh
The company celebrated its 15th anniversary in July 2016. At that time, it was playfully described as a "company in its best teenage years" ( Firma im besten Teenageralter ), having grown to 20 employees and offering over 30 different products. This growth rate of approximately 12.35% year-over-year at the time was a clear indicator of its dynamic trajectory. The team celebrated this milestone in a fittingly local manner with a boat trip on the Salzach River, which flows just 500 meters behind the company's office, demonstrating the strong regional roots of the global player.

Their gateways (like the iKNiX controller ) enable the integration of consumer tech like Google Voice Control and iOS/Android apps into professional industrial automation. Their solution allows engineers to simulate a physical
series (e.g., BAOS 777). These act as gateways between LAN and KNX, allowing web browsers or mobile apps to control building functions. System Infrastructure
By focusing heavily on interoperability and open standards, Weinzierl actively fights against the fragmented, siloed "walled gardens" of proprietary smart home tech. Their work ensures that buildings remain modular, upgradeable, and resilient against obsolescence.
Weinzierl’s commitment to advancing the KNX ecosystem directly supports the global push toward smarter, more sustainable infrastructure. Their products are essential for:
