What does KNX stands for?

KNX is a network standard, basically OSI-based network communications protocol which is extensively designed and developed for building/home automation. KNX is an abbreviation for the word Konnex. KNX is based on three technologies: EIB (European Installation Bus), EHS (European Home Systems Protocol) and BatiBUS.

What is KNX cable used for?

With its excellent electrical and shielded transmission performance, KNX EIB cables can be used for data transmission and to connect building technology systems, allowing the operation and control of lighting and climate control.

Is KNX outdated?

The benefits cannot be overstated; KNX is both simple, yet powerful and comprehensive in its abilities. It does not become obsolete, it can be added to, extended, upgraded, updated, mixed with new and old products and technologies and lastly (and I’m not advocating this) it can run on a piece of wet string.

What is KNX lighting control system?

The KNX system is a bus system consisting of sensors and actuators for room and building automation. With KNX technology, multiple building management disciplines can be implemented for controlling lighting systems, window shades, and room climate control.

Who made KNX?

KNX is the world’s most comprehensive Smart Home system. Gira was one of the founders behind the KNX concept. The Instabus EIB was the company’s first KNX-based Smart Home product. Today, Gira offers a wide range of KNX system solutions.

Is KNX open source?

Is KNX a selv?

Ekinex AB1 and AG1 KNX power supplies provide the network voltage (SELV) to all KNX components. Electrical supply and communication between KNX devices is provided thanks to the inductive supply output voltage.

How many devices can be on a KNX line?

How many devices can be on a KNX System? A single line can have 256 devices. 15 of these lines can be linked to an area and 15 areas can be linked to a backbone line. 256 devices can also installed on each of the area lines and backbone area lines but this includes any area or line couplers .

Is KNX reliable?

The main advantage of KNX is reliability, stability and longevity. If you want every light switch and light fitting to work reliably every time then choose KNX.

How does KNX protocol work?

The KNX system is a bus system for building control. This means that all devices in a KNX system use the same transmission method and are able to exchange data via a common bus net- work.

What is the difference between BACnet and KNX?

In larger functional buildings KNX also covers room automation within building automation. In contrast to BACnet, KNX technology is decentral. There is not just one single automation installation for all intelligence but this intelligence is spread over individual system components.
