Introduction Commissioning is where a KNX RF project either becomes stable and predictable or turns into a long-term service headache. Unlike wired KNX TP, wireless systems demand a bit more planning, correct sequencing, and awareness of RF behaviour during commissioning. This article is written as a practical, on-site guide for system integrators, explaining how to…
Introduction KNX IP problems are some of the hardest issues to diagnose on site.Not because KNX IP is unreliable, but because multiple layers are involved: When something fails, symptoms are often misleading. A structured checklist is the only reliable way to isolate the real cause. This article provides a step-by-step KNX IP troubleshooting checklist, designed…
Introduction Designing a reliable KNX RF system starts with choosing the right device type for the right job. Many RF issues on site are not caused by the protocol, commissioning, or ETS—but by using the wrong RF device in the wrong place. This article breaks down KNX RF device categories—switches, sensors, actuators, and gateways—explaining how…
Introduction One of the most common design questions in KNX projects is deceptively simple: “How many KNX IP routers do we actually need?” The wrong answer leads to overloaded lines, slow communication, and systems that are difficult to expand. The right answer depends on project size, topology, traffic flow, and future growth, not on a…
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…
