We’re here to solve any concern you might have.

The KNX Association has launched a competition to demonstrate how powerful KNX technology can be when it comes to the energy savings and the reduced carbon footprint of smart homes and buildings. The hackathon is open to anyone from all over the world who is able to demonstrate how to save energy using KNX. Any individual or team can participate, including students, hobbyists, professionals, scientific partners, manufacturers, and more. KNX will bring all participants together for both physical and virtual events to deploy the solutions to the challenges set by KNX experts. There are different challenges available, from which participants can choose one or more.

There is no entry fee and no purchase necessary to submit a project.

You can upload multiple projects to the Hackathon platform as long as they tackle different challenges. Duplicated entries will not be shown.

For a successful nomination, here are some considerations teams can consider:


The criteria for selecting winners will be based on measuring how KNX solutions or projects help reduce the use of energy as well as their CO² carbon footprint.


The participating projects should be focussed on solutions for smart homes and buildings that demonstrate energy savings and a reduction of CO² emissions using KNX technology.


Further value will be attributed to projects which also use the latest innovations of KNX IoT technology as well as KNX Secure devices.


For the winner, the KNX Hackathon Competition will be a magnificent marketing tool. KNX Association and its national groups may display the winning projects and teams across their different media outlets.

Challenge 2 – Create the best solution that combines various KNX smart products (such as sensors, actuators, interfaces, monitors, and screens) to reduce the use of energy of different devices.


Challenge 3 – Develop a KNX energy management application that integrates one or more renewable energy sources into a smart home project in the most efficient way.

Challenge 5 – Set your own challenge to create KNX solutions for saving energy or measuring carbon footprint reduction.

The winning projects will be awarded €1,000 per category. The winners for each category will also receive the revered KNX trophy.


Every valid submission will be promoted across different communication channels, and it will be assessed by a specially appointed jury of industry experts that will choose the finalists and winners of the KNX Hackathon 2023. The jury will base its decisions on how and to what extent the submitted KNX solutions or KNX projects contribute to the reduction of the energy consumption and carbon footprint of smart homes and buildings.

The winners will be chosen by a professionally qualified jury, based on the submitted project information, photographic material, videos and documentation. The jury consists of impartial experts of the world of KNX and the KNX Association. The jury will make its decision by simple majority and cannot be challenged by the participants. An individual explanation cannot be given in case one doesn’t receive the award. The jury will come together in July 2023. After the decision of the jury, the nominees of each category will be notified by email.
