Introduction KNX has established itself as the leading global standard for wired and wireless building automation. Among its available media, TP (Twisted Pair) and RF (Radio Frequency Wireless) are the two most commonly used layers for device communication. While TP has dominated traditional installations for decades, RF has rapidly gained relevance due to wireless retrofitting,…
Introduction When system integrators talk about wireless reliability, the discussion almost always comes down to frequency. Many wireless automation systems struggle not because of poor devices, but because the chosen frequency band is crowded, unstable, or poorly suited for buildings. KNX RF takes a different approach. Instead of chasing high data rates, it uses a…
Introduction An undersized KNX power supply rarely causes an immediate, complete system failure.Instead, it creates slow, confusing, and intermittent problems that appear weeks or months after commissioning. This is why power supply issues are among the most misdiagnosed KNX problems worldwide. In this article, we explain what really happens when a KNX power supply is…
Introduction In mission-critical environments, automation failure is not an inconvenience — it is a risk. Hospitals, data centers, airports, control rooms, laboratories, government buildings, and critical infrastructure facilities demand continuous operation, even during faults, maintenance, or partial system failures. KNX is often selected for these projects because of its distributed architecture and long-term reliability. However,…
Introduction Sooner or later, every experienced KNX integrator inherits a project that was poorly designed. Common signs: Migrating such an ETS project is not just a technical task — it is a risk management exercise. One wrong move can break a system that is at least partially working. This article explains how to safely migrate…
Introduction When KNX IP routing stops working, the system often looks partially alive: This creates confusion, finger-pointing, and wasted time. The truth is simple:KNX IP routing fails in very specific and repeatable ways. This article provides a step-by-step method to identify exactly why KNX IP routing is not working and how to fix it, based…
