Introduction KNX IP communication often works silently in the background—until it doesn’t.When KNX telegrams stop reaching devices, ETS downloads fail, or routing behaves unpredictably, the root cause is very often multicast vs unicast handling in the IP network. Many KNX IP problems are wrongly blamed on devices or ETS, while the real issue lies in…
Introduction When a KNX system behaves unpredictably, experienced engineers don’t start by blaming software or devices. They start by checking bus voltage and current. Most KNX communication problems are electrical in nature, even though symptoms look like programming errors. Understanding how to measure, interpret, and troubleshoot KNX bus voltage and current is one of the…
Battery performance is one of the most misunderstood aspects of KNX RF. Datasheets often promise multi-year lifetimes, yet real projects sometimes see batteries fail far earlier. The gap between promise and reality is almost always explained by design choices, configuration, and commissioning behavior—not by the protocol itself. This article is a full technical deep dive…
Wireless automation is often expected to work like magic — place a device anywhere and it simply works. In real buildings, however, reliability comes from planning, not promises. KNX RF is a professional wireless technology designed for homes and buildings, but like all wireless systems, it performs best when its range and coverage are considered…
KNX RF switches are often the first entry point into wireless KNX. They look simple on the surface—just a wall switch without wires—but their reliability, battery life, and user experience depend heavily on correct selection, placement, and configuration. This article is a complete, device-focused guide to KNX RF switches. It is written to be: The…
Wireless technology has matured rapidly, and Bluetooth Mesh is now widely promoted for lighting and smart building applications. Many clients—and even some integrators—ask a reasonable question: “If Bluetooth Mesh is wireless, fast, and popular, why not use it instead of KNX RF?” This article answers that question honestly and technically, without marketing bias. It is…
