Whether it’s a solar installation, an EV charger or a modern heat pump – many key components of a smart building communicate via Modbus. But what happens when the rest of the building technology is based on KNX? This is exactly where a gap often emerges that needs to be closed. With the new PEAKnx KNX Modbus Gateway TCP secure, we now offer an intelligent solution to integrate Modbus-TCP devices into any KNX system – seamlessly, securely and in an especially compact way.
A gateway to greater energy efficiency
The energy transition, increasing demands for energy efficiency and the need for flexible e-mobility present new challenges for smart home owners and system integrators. More and more people want to combine renewable energies, e-mobility and efficient heating solutions in an intelligent way, yet different protocols often prevent a uniform, centralised control. Our gateway provides the solution by reliably integrating Modbus-TCP devices into the KNX world – without any additional software or complicated installation.
One key advantage is its compact design. With a width of just one module unit, the gateway fits easily into even the fullest distribution boards. At the same time, direct power supply via the KNX bus means there is no need for an additional power source.
Of course, security is also ensured: thanks to KNX Secure, all data exchanged between the systems is optimally protected. Especially as networking within the smart home continues to increase, data protection is becoming ever more important – and with this gateway, smart home residents are well prepared for this.
Commissioning is also very straightforward. Using the configuration tool in ETS, up to 250 Modbus data points can be freely configured and flexibly assigned to the desired KNX objects. An integrated test environment allows all settings to be checked in advance directly within ETS, ensuring projects can be launched quickly, safely and efficiently.
It is also particularly practical that we offer preconfigured device files for many common Modbus devices. These can be easily imported into ETS using the free DCA tool. This saves system integrators time and effort during setup, allowing them to focus fully on the specific requirements of their project.
Another advantage is its flexible use: the gateway can operate either as a Modbus master with up to five slave devices or as a slave itself. This means it can adapt flexibly to different project sizes and requirements, whether it is used in a single-family home or in commercial buildings.
How to integrate the KNX Modbus Gateway – step by step
With the PEAKnx KNX Modbus Gateway TCP secure, Modbus-TCP devices can be seamlessly integrated into KNX systems. This step-by-step guide will help you configure everything quickly and smoothly:

Making smart use of data: visualisation and control with YOUVI
When combined with our YOUVI visualisation, the KNX Modbus Gateway TCP secure becomes a key element for intelligent energy management. The energy flows integrated via the gateway – such as PV system yields, EV charging levels or heating data – can be clearly displayed and controlled in YOUVI. With the YOUVI logic module, routines and rules can be created, processes can be automated in a precise way and energy consumption can be optimised – for maximum transparency, greater efficiency and lower costs.
The key to long-term security and efficiency
Like all PEAKnx products, the KNX Modbus Gateway TCP secure is developed and manufactured in Germany. For our customers, this means the highest quality, durable components and a product they can count on in the long term.
The PEAKnx KNX Modbus Gateway TCP secure unlocks even greater potential in modern building automation. It creates the foundation for seamless communication between energy systems and KNX, ensures maximum flexibility in implementation and enables truly smart energy management.
