From legacy hardware to certified Matter products: The Mill Norway project journey
See how we helped Mill Norway upgrade existing wall heaters via firmware and design a brand-new, certified smart plug from scratch.
Inside the case study: our 3-stage approach
Phase 1: legacy code audit & Matter migration
Evaluating existing hardware capabilities and porting the Matter stack to field-deployed units without changing the BOM.
Phase 2: Next-gen hardware & PCB Design
Transitioning from software-only support to full schematics, component selection, and prototype layout for a new smart plug.
Phase 3: Pre-compliance & official launch
The strategic steps taken to successfully navigate the CSA testing requirements and secure official Matter certification.
Why partner with WizzDev for Matter migration?
DEEP ESP32-C6 & MATTER SPECIALIZATION
We have deep, hands-on experience optimizing the ESP-Matter SDK and managing the chip’s tight 512KB RAM limits.
PRE-COMPLIANCE VALIDATION
We pre-test your hardware against the official chip-tool test harness, catching commissioning bugs and memory leaks before you pay for a formal, expensive lab run.
ZERO-LAG CET COOPERATION
Working in your timezone means instant communication, matching engineering hours, and fast, customs-free shipping of physical hardware across Europe.
100% IP OWNERSHIP
Every line of firmware code and CAD file belongs to you. No licensing fees, no royalties, and zero vendor lock-in.
