This year’s Matter Day in China was nothing short of energising. With a growing audience, engaging demos, and a compelling talk on interoperability, the event offered a powerful platform to demonstrate leadership in the smart home and IoT ecosystem. 

A bigger, bolder Matter Day  

The event was significantly larger than the previous year, with double the number of booths and attendees. The scale reflected the growing momentum behind Matter and the increasing interest in interoperability testing. It was a great opportunity to connect with the community, showcase capabilities, and reinforce our role as a trusted partner in the CSA ecosystem. 

Engaging demos and real conversations

Day one was all about interaction. The booth attracted many visitors, The standout attraction? A live demo showcased our approach to interoperability automation testing. 

The demo, focused on CSA-requested interoperability testing, sparked curiosity and conversation. Visitors wanted to know how we could help them pass certification tests and improve their product experience. The process helped demystify the technical aspects and positioned the team as knowledgeable and approachable. 

To make the experience more tangible, the team used a Rubik’s Cube as a conversation starter—an inventive way to explain the complexity of testing in a way that resonated with attendees. It was a simple but effective tool that helped bridge the gap between abstract services and real-world understanding. 

Keynote on interoperability as a strategic advantage 

On day two, Fan Zhang, Testing Operations Director with Resillion gave a keynote about the importance of interoperability testing in the Matter ecosystem. While certification is often seen as the final step, Fan challenged that notion, encouraging manufacturers to view it as just the beginning. 

He outlined how interoperability testing can unlock deeper collaboration with major ecosystem players like Apple, Google, Amazon Alexa and Samsung. By following theright processes, manufacturers can go beyond the Matter logo and achieve seamless integration across platforms. 

Fan’s message was clear: interoperability isn’t just about compliance, it’s about quality, user experience and long-term success. His talk, delivered near the end of the day, still managed to spark follow-up conversations and even prompted feedback from major players like Samsung, who engaged directly with him after the session.

Strengthening our role in the CSA and Matter China Group 

Participation in Matter Day goes beyond demos and talks. As an active member of the CSA and the Matter China Group (CMGC), we contribute to localisation efforts, participate in developer contests, and support the growth of the ecosystem. 

This year, the team played a key role in testing entries for the developer contest, helping to identify and reward innovation. Being part of the CMGC also provides access to some of the biggest names in the industry, including Tuya, Samsung, and chipset providers like NXP and Espressif. It’s a long-term investment in relationships and reputation—one that positions us well in the region’s smart home landscape. 

Internal growth and team development 

The event also served as a valuable learning experience. For some, it was their first time participating in such an event. Watching colleagues engage with clients, answer technical questions, and represent the company with confidence was a moment of growth. It’s not just about external visibility, it’s about building internal capability and confidence.

Looking ahead

With Matter Day growing in size and influence, we’re already looking forward to next year’s event. The opportunity to speak directly with CSA board members, share our differentiators, and influence the direction of interoperability testing is one we don’t take lightly. 

 “We’re not just here to test. We’re here to help shape the future of interoperability, Resillion’s role in the Matter community is only just beginning,” says Fan Zhang.
