KNX RF motion sensors are among the most powerful—but also most misunderstood—wireless KNX devices. They influence lighting comfort, energy efficiency, HVAC logic, and overall user satisfaction. At the same time, they are one of the largest contributors to RF traffic and battery consumption when designed incorrectly. This article is a full technical yet readable guide,…
Introduction Modern building automation projects increasingly combine wired and wireless technologies to balance reliability, flexibility, and installation speed. In this hybrid approach, one component plays a critical role: the KNX RF Gateway. It acts as a bridge between wireless KNX devices and the rest of the automation system, allowing them to communicate seamlessly with wired…
Introduction Energy monitoring is no longer an optional feature in modern buildings. Rising energy costs, sustainability goals, and regulatory pressure have pushed clients to ask a simple question: “Where is our energy actually going?” KNX plays a critical role in answering this question — not just by measuring energy, but by connecting consumption data with…
Selection of KNX RF devices is not a product decision—it is a system design decision. Most long-term KNX RF problems (battery complaints, unreliable behaviour, delayed response, repeated service calls) are not caused by wireless technology itself. They are caused by choosing the wrong RF device for the wrong role. This article is a full technical…
Introduction Power supply sizing is one of the most underestimated aspects of KNX system design. In small projects, mistakes often go unnoticed. In medium and large KNX installations, however, incorrect power supply calculation leads to unstable communication, random device failures, difficult commissioning, and long-term maintenance issues. This guide explains how to calculate KNX power supply…
Introduction In small KNX installations, IP communication is often treated as a convenience. In large KNX projects, however—such as hotels, office buildings, campuses, and high-rise residential towers—the KNX IP router becomes a critical backbone component, not an accessory. A poorly designed IP routing strategy can lead to unstable communication, slow commissioning, multicast storms, or even…
