Human-machine interface for Thermomix® TM7

Vorwerk, a global leader in high-quality household appliances, developed a new version of their renowned Thermomix® device. They aimed to equip the Thermomix® TM7 with an advanced human-machine interface (HMI). The newest model was to be controlled fully from the touch panel, without a physical knob present in previous versions.

The main challenge was to develop a visually appealing, smooth, and feature-rich HMI that would operate effectively on hardware with limited resources. The solution also had to lay a strong foundation for future development—building a scalable platform that supports new features and continuous product innovation.

From PoC to production

Our collaboration with Vorwerk began in 2022, starting with a proof of concept (PoC) phase to identify the most suitable technology. The Spyrosoft team showcased the potential of Qt as an HMI framework, which was later chosen by Vorwerk.

Scope of the work

Our responsibilities involved designing HMI architecture, developing scalable HMI software, conducting quality assurance tests, and ensuring smooth operation on constrained hardware. The focus was on creating a flexible framework that enables seamless collaboration across teams, supporting long-term scalability and continuous innovation.

A cross-functional team

We formed a dedicated team of experts, including:

• Qt software developers,
• QA engineers using Squish and Robot Framework,
• a product owner,
• a scrum master.

The team supported selected HMI areas. A Spyrosoft Product Owner and Agile Master joined Vorwerk to ensure seamless collaboration.

Spyrosoft experts took on key roles, shaping technical decisions and expanding Qt expertise within Vorwerk, enabling the engineers to further develop and scale the platform.
