KNX and Home Automation Glossary

Communication protocol for lighting control, often integrated into KNX installations via a gateway.

Device allowing adjustment of lighting intensity. KNX dimmers are compatible with different types of light sources (LED, halogen, incandescent) and allow creation of personalised ambiances.

Official software for configuring and programming KNX installations.

Address used for functional communication between KNX devices (format: main group/middle group/sub-group).

Integration of the KNX protocol into the open-source Home Assistant home automation platform. Allows combining KNX equipment with other protocols (Zigbee, Z-Wave, WiFi) and extending automation possibilities.

Set of techniques for automating building equipment (lighting, heating, blinds, etc.) to improve comfort, security and energy efficiency.

Interface allowing connection of a KNX installation to the computer network (Ethernet/WiFi). It enables remote control via smartphone or tablet, integration with visualisation servers and communication between multiple KNX lines.

Worldwide open standard for home automation and building control. It enables the control and automation of various functions such as lighting, blinds, heating, ventilation, air conditioning, security, etc.

Device that receives telegrams via the KNX bus and executes commands such as turning lights on/off, raising/lowering blinds, etc.

Communication line through which all KNX devices exchange information in the form of telegrams.

Device enabling the KNX system to communicate with other systems or protocols (DALI, Modbus, BACnet, etc.).

KNX transmission via the Internet Protocol (IP), enabling the use of Ethernet or Wi-Fi networks for KNX communication.

Professional certified by the KNX Association, having completed official training and passed the certification exam.

Device providing the electrical power necessary for devices connected to the KNX bus.

Wireless KNX transmission via radio frequency, mainly used for renovations or extensions of existing installations.

Security extension of the KNX protocol integrating encryption (AES-128) and authentication of communications. Protects the installation against unauthorised access and hacking, particularly important for sensitive buildings.

Device that detects physical events (presence, brightness, temperature, etc.) and transmits them on the KNX bus as telegrams.

Message sent on the KNX bus containing information such as source address, destination address and data to be transmitted.

Wall-mounted visualisation and control interface for KNX installation. Allows control of all home automation functions (lighting, heating, blinds, scenarios) via an intuitive graphical interface. Brands: Gira, ABB, Zennio, Basalte.

KNX transmission via twisted pair cable, the most common transmission medium in KNX installations.

KNX simulation software allowing testing and validation of installation programming without physical equipment. Useful for training, scenario testing and debugging before commissioning.

Graphical interface allowing control and monitoring of a KNX installation via a computer, tablet or smartphone.

Outdoor KNX sensor measuring climatic conditions: wind (speed and direction), rain, brightness, temperature. Enables automation of blinds according to weather and protection against bad weather.

Range of designer KNX switches and controls from Legrand. Available in various finishes (white, titanium, graphite), it integrates into the Celiane wiring system for a coherent aesthetic.

KNX device allowing connection of different KNX lines to each other and filtering telegram traffic.

System allowing automation of movement for shutters, blinds, curtains or gates. Three main types: wired (direct connection to electrical panel), wireless (RF), or solar (autonomous with photovoltaic panel).

Unique address assigned to each KNX device to identify it on the bus (format: area.line.device).

Sensor detecting movements and/or presence of people in a room. Used for automation of lighting, heating, air conditioning and security systems. KNX detectors can combine multiple technologies (infrared, ultrasound, radar).

Set of predefined commands executed simultaneously or sequentially to create a particular ambiance or situation.

Complete range of KNX products from Siemens for building automation. Includes actuators, sensors, interfaces and communication modules for residential and commercial installations.

Home automation control centre that allows you to control and automate connected home equipment (lighting, heating, blinds, etc.). KNX hubs offer superior reliability and interoperability compared to consumer hubs.

Roller shutter equipped with a motor and communication module allowing remote or automated control. Can be integrated into a KNX installation for automatic scenarios (sunrise/sunset, presence simulation).

Smart home switch allowing control of lighting and other equipment with advanced functions: dimmer, scenes, time programming. KNX switches come in push-button, touch or screen versions.

Intelligent temperature regulation device allowing remote control of heating or air conditioning. Integrated into the KNX system, it automatically optimises energy consumption according to occupancy and habits.

Device allowing connection of a computer to the KNX bus via USB or IP for programming or visualisation.

Means of controlling a home automation installation: wall touch screens, tablets, smartphone apps, remote controls or voice commands. A good user interface is intuitive and allows quick access to essential functions.

Schneider Electric solution combining the KNX protocol with intelligent energy management. Enables consumption monitoring, energy optimisation and control via mobile app.
