Overview
- The Connectivity Standards Alliance published the Matter 1.6 specification and SDK and announced Product Security 1.1 on June 17, 2026, at its Unify conference in Austin, Texas.
- Matter 1.6 adds NFC-Based Commissioning that completes the entire setup exchange over bi-directional NFC so devices can be commissioned before they are powered or installed.
- Joint Fabric creates a single shared Matter network that lets multiple authorized controllers co-administer devices so an item added once becomes accessible across participating ecosystems.
- Thermostat Suggestions let controllers send time-bound recommendations that a thermostat evaluates against user preferences and recent inputs to avoid conflicting commands from different platforms.
- Product Security 1.1 expands certification from single devices to whole IoT systems, defines two assurance levels with Authorized Test Laboratory review and independent testing, and maps to EU and Singapore cybersecurity rules while real-world rollout depends on platform and device-maker adoption.
