February 2026 – Matter 1.4 Certification Testing Begins
TÜV Rheinland has been officially authorized to test Matter 1.4, the latest version of the universal smart home standard. This authorization enables manufacturers to certify Matter 1.4 compliant devices, including PIR motion sensors with enhanced occupancy sensing capabilities. [citation:6]
Key new features in Matter 1.4 relevant to PIR sensors include:
- Occupancy Sensing Cluster Updates: Enhanced reporting and configuration options for occupancy detection
- Intermittently Connected Devices (ICD) Support: Optimized for battery-powered sensors that wake periodically
- Energy Management Improvements: EVSE enhancements for solar power, battery, heat pump, and water heater integration
- Access Restriction Lists (ARLs): Improved security for sensor data access
The Matter 1.4 specification includes significant updates to occupancy sensing functionality, allowing PIR sensors to report not just binary occupancy status but also configurable sensitivity and hold time parameters. This enables more sophisticated automations based on room occupancy patterns. [citation:6]
TÜV Rheinland has authorized test locations for Matter 1.4 in Bochum (Germany), Shenzhen and Shanghai (China), Yokohama (Japan), Seoul (South Korea), and Taipei (Taiwan). Version 1.3 testing is available now, with 1.4 testing capabilities coming soon. [citation:6]
The Connectivity Standards Alliance (CSA) continues to expand Matter’s capabilities, with occupancy sensing being a key focus for smart home automation and energy management applications. PIR sensor manufacturers are expected to release Matter-certified products later in 2026.
