What is KNX?

KNX is the worldwide STANDARD for all applications in home and building control, ranging from lighting, heating, ventilation, air conditioning, shutter control, security systems, monitoring, alarming, energy management, smart metering as well as household appliances, audio/video and a lot more. 

Shortly, a KNX installation consists of sensors, actuators, system devices and a transmission medium (TP1 installation: 2-wires twisted-pair bus cable).

A sensor is a home automation device that sends commands, controls or adjustments to other home automation devices. Sensors may be for example pushbuttons, thermostats, motion or presence detectors, or brightness temperature sensors, touch-screen units, weather stations, etc. Each of these devices detects a physical quantity and encodes it in a message (telegram) which then sends on the bus.

An actuator is a home automation device that receives commands, controls or adjustments sent by other home automation devices. Actuators may be for example binary outputs, dimmer, output units for motor drives, actuators for HVAC terminals, display units, etc. Each of these devices receives a message (telegram) from the bus and translates it in an action for which it was configured: on, off, brightness adjustment, motor running, displaying information, etc.

KNX has been defined for the digital transmission on twisted-pair cables (KNX-TP), powerline on power supply cables (KNX-PL), wireless as radio frequency (KNX-RF) and through the Internet Protocol on data networks (KNX-IP). There are also KNX devices that use the wireless transmission infrared (IR) for local communication between sensor and actuator within a room.

Many useful information are available simply accessing the website of the international association www.knx.org. If your interest is of a professional kind (you are a planner, an installer or a system integrator) you can deep your knowledge buying a copy of the KNX Handbook for Home and Building Control, available in several languages. The next step may be to take part to a training course at a KNX-certificated training center.

The KNX Partner Ranking is a rating system especially designed for KNX partners whereby KNX partners are displayed on the KNX partner website based on their strengths. These strengths are represented through five categories: knowledge, tools, engagement, realized KNX projects and customer feedback. The goal of the KNX Partner ranking system is to help the end customer find the right KNX partner.
