What Is KNX and How Does It Work?
KNX is an open standard for commercial and residential building automation. It allows products from different manufacturers to be integrated into one smart home system.
How KNX Works
KNX uses a decentralized approach where each device on the network has equal access. There is no central controller. Instead, the devices themselves determine how to route and share information with each other over the KNX bus.
- KNX devices like sensors, actuators, and interfaces are installed in the building and connected to the bus. The bus is the network cable that links all KNX devices.
- Each KNX device has its own electronic address to identify itself. This allows for two-way communication between devices on the network.
- The devices can be programmed to automate specific functions in response to triggers. For example, motion sensors can detect when someone enters a room and signal the lights to turn on. Or a timer can automatically lower window blinds at sunset.
- KNX uses a common, standardized communication language so that devices from different manufacturers can work together seamlessly. This interoperability is a key benefit of KNX for smart home integration.
By connecting your KNX installation to Google Home, you get voice control and automation of all your KNX devices. Lights, heating, blinds, and more can be controlled by voice commands or customized Google Home routines and schedules. KNX with Google Home provides a simple yet powerful smart home solution.

Required Hardware for KNX Google Home Integration
To integrate KNX with the Google Home smart speaker, you will need a KNX IP interface and a KNX USB interface.
KNX IP Interface
The KNX IP interface connects the KNX bus to your local area network (LAN) and the Internet, enabling communication between the KNX installation and the Google Home. It translates the KNX telegrams into IP telegrams and vice versa. The IP interface is connected directly to the KNX bus and to the router. Popular options include the Gira KNX IP Interface and the Schneider Electric KNX IP Interface.
KNX USB Interface
In addition to the KNX IP interface, you will need a KNX USB interface to connect your Windows PC to the KNX bus during the integration process. The USB interface is only required temporarily during setup to program the KNX IP interface. Once programming is complete, the USB interface can be disconnected. Look for a KNX certified USB interface from manufacturers like Weinzierl or ETS.
With these two essential pieces of hardware-the permanent KNX IP interface and the temporary KNX USB interface-you will have the basic components to get started with integrating your KNX smart home installation with the Google Home and enabling voice control of devices like lights, thermostats, blinds and more. The IP interface handles the connection between the KNX bus and your network, while the USB interface is only needed during initial programming to configure the IP interface to work with your specific KNX system and components. By purchasing certified KNX interfaces, you can ensure full compatibility and support for integrating with the Google Home smart speaker.
