Dining room with KNX operating panel on wall


KNX is a renowned international standard for intelligent electrical installation networking based on a bus system. Many manufacturers have now adopted the KNX standard and offer a vast range of KNX-certified products. You can find the right product for almost any application.

KNX intelligent networking uses a cable, which for new builds is generally installed together with the power supply. However, you can also send KNX commands via a wireless system or the existing power circuit. With the KNX system, you can effortlessly control and automate things such as lighting, blinds, heating, ventilation and security installations.

If you want a broad range of control options, such as using a smartphone or tablet, opt for a smart home nerve centre such as the Gira HomeServer. It connects the KNX installation to the computer network and the internet, enabling you to control your home from an app – from wherever you are.

Expanding the KNX system with the Gira HomeServer lets you seamlessly integrate several other technologies into your building control system – such as door intercoms, camera and sound systems as well as systems by other manufacturers for the bathroom, kitchen and home entertainment. That way, you can enjoy maximum convenience, security and energy efficiency in your home.

The Gira HomeServer must be installed and configured by a professional. It is also wiser to call a specialst if you want to make any changes to settings, as you can't really do this yourself.
