Seamless Hardware-Software Integration for Vaillant 's HVAC Systems
Epteck GmbH partnered with Vaillant to develop a customized Board Support Package (BSP) for their HVAC systems and internet gateways. Using technologies like C, C++, Python, Yocto, and Robot Framework, the project aimed to improve hardware-software integration and enhance development efficiency.
Epteck completed the BSP development, increasing application development efficiency by 80% through cross-toolchain support. The structured logging system reduced critical issue resolution time by 40-50%, and OTA updates eliminated the need for physical device access, saving up to 50% in operational costs. These updates also reduced bricked systems to about 2%, improving overall system reliability. Early issue identification further optimized the development lifecycle, streamlining Valliant’s operations.

What We Did to Solve the Problems
Epteck completed BSP development to ensure seamless hardware-software integration and provided cross-toolchain support to enhance application development efficiency.
Customized BSP for Seamless Integration
We developed a tailored Board Support Package (BSP) to ensure seamless hardware-software integration. This optimization improved system efficiency, enabling smoother operations and better hardware compatibility.
Cross-Toolchain Support for Enhanced Development
To boost development flexibility, We provided cross-toolchain support, allowing applications to be built across multiple platforms. This approach increased application development efficiency by 80%, streamlining the overall process.
Optimized Logging for Faster Issue Resolution
We implemented a detailed logging system, significantly improving issue tracking and debugging. This enhancement reduced critical issue resolution times by 40-50%, ensuring more stable and reliable system performance.
Over-the-Air (OTA) Updates for Cost Efficiency
The introduction of OTA updates eliminated the need for physical access to devices for software maintenance. This innovation led to a 50% reduction in operational costs, improving the scalability and maintainability of the system.
Proactive Unit Testing and Monitoring
Epteck emphasized unit testing and continuous monitoring to identify and address issues early in the development lifecycle. This proactive approach minimized risks and enhanced system reliability, ensuring a robust and efficient solution for Vaillant.

Vaillant's Experience with Epteck
Professional, Solution-Oriented YOCTO BSP Experts
We commissoned epteck to support our inhouse custom STM32MP1 based hardware. They were mostly working on the YOCTO BSP layers, including building secure boot support, YOCTO release upgrades, device tree work. Khalil and his team have always been professional, responsive and knowledgable. I’ve been impressed with the depth of their understanding of YOCTO and BSPs. The conversations were always solution oriented and we achieved our goals in time. I hope to continue to collaborate with them and can only recommend them to other customers.
