The story begins not with a crisis, but with a sigh.
In a 12th-century castle converted into a hotel, drilling holes for new sensor wires is illegal. Weinzierl offers wireless KNX RF (Radio Frequency) gateways. These devices bridge radio KNX sensors (motion, window contacts) to the wired KNX backbone, preserving the stone walls while offering modern automation.
At first glance, it’s a simple router. Deep dive: It is one of the most stable, low-latency KNX-to-IP converters on the market. It supports KNX Security (encryption) natively. In critical infrastructure (hospitals, data centers), this device is the silent workhorse.

Ensuring that smart building data remains private and secure from external threats.
Weinzierl Engineering GmbH is the epitome of the hidden champion . They do not seek brand recognition. They seek the respect of the 10,000 KNX integrators worldwide. For any engineer tasked with making a building "smart" without creating a maintenance nightmare, Weinzierl is not a luxury—it is a necessity. They are the plumbers of the digital building: unseen, unglamorous, but absolutely critical. When their products fail, nothing works. When they work, nobody notices. And that is the highest compliment for building infrastructure.
Weinzierl is regularly present on the global stage, showcasing its technology at industry-leading events. It demonstrates its solutions at the world's largest trade fair, Integrated Systems Europe (ISE) , and The BIG 5 construction exhibition in the Middle East. At Light+Building 2026 , the company launched several new KNX products, including a KNX secure valve actuator and a mini KNX server. These devices bridge radio KNX sensors (motion, window
: They were instrumental in the development and implementation of KNX IP and KNX Data Secure , providing the necessary security layers for smart buildings to resist cyber-attacks.
Weinzierl is a leading developer of KNX Stacks (the underlying communication software) for various media, including Twisted Pair (TP), Radio Frequency (RF), and Ethernet (IP). Their NGS (Next Generation Scalable) stack is widely used by OEM partners across millions of devices. Main Product Lines
At the heart of Weinzierl’s operations is the , the worldwide open standard for intelligent building control. The company's focus on building networking based on this standard is total; its products and solutions cover the KNX system comprehensively. Weinzierl’s specialization lies in interface and gateway solutions , which are system devices with high complexity, bridging KNX with other systems and technologies.
The company’s core thesis was simple but radical for its time: Building automation protocols (KNX, Modbus, BACnet, EnOcean) shouldn't live on islands. They need to speak fluent IP.
