In our blog post from June 9, we walked you through tips, technical resources and IoT products that enable Matter. This second post walks you through a technical use case on how Matter connects your smart home business. This case uses Infineon's solutions to securely can connect over Matter and demonstrates how smooth interoperability between Thread and Wi-Fi can work in the smart home. This use case works is designed for smart locks, but also works for smart lighting, and radar presence detection applications.
How it works
The use case setup contains five nodes:
- Two light nodes,
- Two radar presence detection nodes
- A smart lock node.
All the 5 nodes are provisioned through a Raspberry Pi controller managing the Smart Home. The light nodes use Matter protocol over Thread. The lock and presence nodes will use Matter Protocol over Wi-Fi. The Raspberry-Pi will act as a bridge, Open Thread Border router, connecting the thread and Wi-Fi networks together. This setup enables seamless operation between the five nodes. The presence node and smart lock node will provide the data necessary to switch ON/OFF the light nodes.
How is the physical arrangement of hardware?
The demo area is split into two portions: porch and living room. This setup is used to simulate simple actions in the smart home such as turning on an interior light if the door is unlocked.
How the products work together
The powerful ULP PSoC™ 6 microcontroller as the solution's brain and acts as a sensors hub. Devices used for lighting, locks, and radar presence detectors are connected to PSoC™ microcontroller but using different mediums, Thread and Wi-Fi. Matter enables the interoperability between the Thread and Wi-Fi devices. Matter runs on the on AIROC™ CYW30739 multi-protocol SoC (over Thread) and AIROC™ CYW43012 ultra-low power single-chip, combo device (over Wi-Fi). The demo also uses NFC and CapSense access control for the door lock.
