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…
Introduction KNX RF installations are often blamed when something “randomly” stops working. In reality, most KNX RF issues are predictable, detectable, and preventable—if you know where to look. Unlike wired KNX TP, wireless behaviour exposes design and installation mistakes very quickly. This article is written for system integrators and commissioning engineers. It focuses on real…
Introduction KNX has existed for decades in an industry where many technologies disappear within a few years.This alone raises an important question: How does a protocol designed for long-life buildings remain relevant in a cloud-driven, API-centric, IoT world? The future of KNX is not about replacing what already works.It is about extending a proven, deterministic…
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…
