Induction HOB with Celsius° Cooking
The project was about implementing a Bare-metal firmware compliant with Safety Class B, both secure core and application parts, for kitchen appliances – Induction Cooktops. The Developex team worked on firmware for various configurations of hardware and further firmware adaptation for a new subset of products.

Developex role:
The Client was responsible for Hardware, Bootloader software, Cloud services backend, manual QA, and 3rd party Firmware and Hardware, which we integrate.
During the project, our team created such project documentation as Software Architecture documentation, a Phase roadmap, a Safety Certification Submission document, and a QA bug tracking spreadsheet with a pipeline.
Time reports, release notes, and roadmap plans were prepared and provided regularly, which, together with close communication on the project status, detailed planning of project phases, and scope estimations, allowed us to get the project intro deadlines.
One of the biggest challenges was meeting the very strict and demanding deadlines.
Our contracts had upper-bound fixed costs, which we are not allowed to exceed. We had to ensure budget predictability.
Specification revisions introduced far more work than initially anticipated. However, we were able to successfully change the Firmware logic and do new integrations while still meeting our deadlines.
Work with and support the 3rd party teams throughout the project
We closely monitored every change or request made. This allowed our Client to have control over the situation.
In response to spec updates and even later requests from the QA team, we reoptimized the Firmware to let all the changes “fit into” the existing Hardware, which was not changing during later project stages.
Developex introduced the QA bug tracking process to the Client QA teams to help their work and impact happen more efficiently and save time for the project.
We communicated frequently with everyone on different levels, and the team showed a lot of teamwork and leadership skills in many areas. This supported our main counterparty Managers and Tech Lead by giving them not only visibility but also choices and options, predictability, and forecasting, which was greatly appreciated by the Client team.

The Developex team offers constant project after-release support to address any requirements or requests for possible improvements or fixes. Typical tasks include investigating and proposing workarounds, debugging (including Hardware), tracing back complex errors and artifacts, making improvements, and addressing specification updates.
Developex delivered secure, high-performance firmware for smart kitchen appliances. Our focus on transparency, collaboration, and innovation ensured a seamless development process that met strict deadlines and evolving specifications.
Provided regular updates and clear reporting to maintain full project visibility.
Worked closely with Gorenje and third-party teams to ensure smooth integration.
Successfully adapted to changes in specifications while maintaining project deadlines.
Developed cutting-edge, safety-compliant firmware that enhanced the functionality of smart kitchen devices.
The project is based on previous firmware development work done by the Developex team, which allowed scaling the project for a new subset of kitchen appliances and reusing of the project architecture. The new subset included a new Hood with integrated extraction.
As part of this project, Developex was responsible for adapting the Firmware to meet slightly different requirements while also preserving the main parts of the previously developed project.
In addition, we were tasked with adding new features available only for the new Hardware:
Despite having to deal with new Hardware limitations, we successfully delivered on the project.
A smart remote control device is an innovative tool that enables users to seamlessly control a variety of connected smart home devices.
The smart home system makes home security simple, as its multi-room protection technology better protects what you care about most.
