Introduction Few things worry a client more than hearing: “Some KNX devices are offline.” Even more frustrating is when devices: In most cases, the devices themselves are not faulty.They are reacting to electrical, communication, or design issues that were hidden during early stages. This article explains the real root causes behind KNX devices going offline,…
In KNX RF systems, gateways are not accessories. They are core infrastructure components that directly determine performance, reliability, and scalability. Many RF-related issues—delays, missed commands, battery drain, or intermittent failures—can be traced back to gateway capacity limits, poor zoning, or lack of redundancy. This article is a full technical deep dive for consultants and system…
Introduction As soon as KNX systems move from twisted pair to Ethernet, network equipment becomes part of the automation system. Among all network devices, the managed switch has the biggest impact on KNX IP stability. Many KNX IP problems are not caused by routers, ETS, or devices. They are caused by default switch settings that…
Introduction As KNX systems move onto Ethernet backbones, they no longer live in isolation. They share switches, routers, and cabling with IT networks, CCTV, Wi-Fi, AV, and servers. In such environments, VLAN design becomes critical. Many KNX IP problems are not caused by KNX devices or ETS configuration, but by poor or missing VLAN planning….
Introduction KNX projects grow in complexity very quickly. What starts as a single line often expands into multiple lines, floors, or even buildings. At that point, couplers become critical components of the system architecture. Two terms often create confusion: They look similar, appear similar in ETS, and sometimes are even the same physical device. Yet…
Introduction The Digital Addressable Lighting Interface (DALI) is one of the most widely adopted lighting control standards, offering flexibility, reliability, and easy integration with building automation systems. But to unlock the full potential of DALI, correct wiring and topology design are essential. Unlike traditional analog dimming systems (like 1–10V), DALI uses a two-wire digital bus…
