Matter 1.4.2 | Enhancing Security and Scalability for Smart Homes
Matter 1.4.2 Update: Key Highlights
- Wi-Fi-Only Commissioning
- Devices can now onboard via Wi-Fi Unsynchronized Service Discovery (USD), eliminating the need for Bluetooth LE.
- Reduces hardware costs and enables firmware updates for existing Wi-Fi devices.
- Enhanced Security
- Vendor ID Verification ensures Admins (ecosystems) are authentic.
- Access Restriction Lists (ARLs) protect network infrastructure settings.
- Certificate Revocation Lists (CRLs) block compromised devices.
- Improved Scenes Management
- Standardized support for scenes with the ability to create temporary effects (e.g. fade-out).
- Faster, more synchronized execution across devices.
- Optimized Network Efficiency
- “Quieter Reporting” reduces unnecessary data traffic, improving battery life and responsiveness.
- Standardized Node Reconfiguration
- Devices automatically notify controllers of new features after updates, avoiding reconfiguration.
- Consistent Endpoint Unique IDs
- Prevents duplicate devices when reconnecting or switching ecosystems.
- Robot Vacuum Cleaner (RVC) Standardization
- Predictable behavior for commands (e.g., no need to cancel jobs manually).
- Stronger Network Infrastructure Requirements
- Thread Border Routers must support 150+ devices (Thread 1.4).
- Wi-Fi APs need 100+ connectionsand Target Wake Time (TWT) for efficiency.
- Faster, More Reliable Certification
- Updated test plans for valves, fans, and access control ensure better device quality.
