As someone deeply interested in smart home solutions, I’ve been following the advancements in Matter protocol with great enthusiasm. Matter promises a unified standard for smart home devices, enabling seamless integration across different ecosystems. In this post, I’d like to share my experience testing Nordic Semiconductor’s nRF Connect platform with Apple, Google, and Samsung ecosystems.
What is Matter?
Matter is an open-source protocol designed to simplify smart home device integration. It supports both Thread and Wi-Fi connectivity, allowing devices to work together regardless of their underlying wireless technology. This is particularly exciting for users who own devices from multiple ecosystems.
Testing Setup
For my experiment, I used:
- Nordic Semiconductor’s nRF52840 DK (for Matter over Thread)
- nRF7002 DK (for Matter over Wi-Fi)
- Apple iPhone (iOS 16.1+)
- Google Nest Hub (2nd generation)
- Samsung SmartThings Hub
Commissioning Devices
-
Matter over Thread with Google Home
- I started by commissioning the nRF52840 DK to the Google Home ecosystem. The process involved scanning a QR code generated by the device and following the on-screen instructions in the Google Home app. The device was successfully added and could be controlled via voice commands.
-
Matter over Wi-Fi with Apple Home
- Next, I commissioned the nRF7002 DK to the Apple Home ecosystem. Using the Apple Home app, I scanned the QR code and completed the setup. The device appeared in my list of accessories and could be controlled through the app.

Sharing Devices Across Ecosystems
- One of the standout features of Matter is its ability to share devices across multiple ecosystems. I tested this by sharing the Thread device from Google Home to SmartThings and vice versa. The process involved generating a setup code in one ecosystem and using it to commission the device in another. It worked seamlessly!
Challenges and Solutions
- Setup Discriminator Values: Initially, I faced an issue where multiple devices with the same discriminator value caused conflicts. Nordic Semiconductor’s documentation suggests using unique values for production environments. I updated the discriminator values in the firmware and re-flashed the devices, resolving the issue.
- QR Code Generation: Generating new QR codes after changing discriminator values was a bit tricky. Nordic provides a URL in the device logs that can be used to generate QR codes. I found this method reliable once I understood the process.
Conclusion
This experiment reinforced my belief in Matter’s potential to revolutionize the smart home landscape. The ability to commission devices across ecosystems and share them between platforms is a game-changer. While there are still some learning curves, especially for developers, the future looks bright for Matter.
If you’re interested in diving deeper, I recommend checking out Nordic Semiconductor’s Matter documentation and their sample applications. Happy experimenting!
