The Connectivity Standards Alliance (CSA) has released the Matter 1.4 specification, introducing Enhanced Multi-Admin background synchronization, native Home Energy Management System (HEMS) clusters, and standardized router integrations.
The Connectivity Standards Alliance (CSA) has officially published the Matter 1.4 specification, expanding the standard beyond basic lighting and smart plugs to include complex domestic energy management and streamlined multi-ecosystem sharing.
In this technical breakdown, we examine the architectural updates in Matter 1.4, how Enhanced Multi-Admin (EMA) improves commissioning workflows, and how new energy management clusters operate across Matter-over-Thread and Matter-over-Wi-Fi networks.
1. Enhanced Multi-Admin: Streamlining Cross-Platform Sharing
Matter’s Multi-Admin feature allows a single device to connect simultaneously to multiple ecosystems (e.g. Apple Home and Home Assistant). In earlier Matter versions (1.0–1.3), sharing required generating a temporary numeric code for each platform. Matter 1.4 introduces Enhanced Multi-Admin (EMA):
| Workflow Dimension | Matter 1.0–1.3 Architecture | Matter 1.4 Specification |
|---|---|---|
| Cross-Ecosystem Sharing | Manual generation of 11-digit pairing codes per device per platform. | Automated Fabric Consent. Users approve sharing at the home level; devices synchronize across ecosystems in the background. |
| Device Discovery | Requires placing devices in pairing mode individually. | Ecosystems communicate over the local network via mutual TLS to exchange operational certificates. |
| Commissioning Workflow | Repetitive when commissioning multiple devices. | Single-prompt authorization for newly added hardware. |
2. Home Energy Management Systems (HEMS) Architecture
Matter 1.4 introduces a suite of bidirectional Home Energy Management System (HEMS) device clusters:
- Electric Vehicle Supply Equipment (EVSE): Standardizes EV charging controls, allowing platforms to dynamically throttle charging current based on solar generation or utility pricing schedules.
- Heat Pumps & Water Heaters: Introduces thermodynamic device types capable of scheduled pre-heating and demand-response load shifting.
- Solar Inverters & Battery Energy Storage (BESS): Native clusters for reporting solar generation, battery state of charge (SoC), and grid import/export power flows.
3. Home Routers & Access Points (HRAP)
Matter 1.4 formalizes the Home Router and Access Point (HRAP) device type, allowing residential Wi-Fi routers to integrate directly into Matter fabrics with embedded Thread Border Routers.
4. Adoption & Ecosystem Timeline
As with all CSA specification updates, adoption progresses through SDK integration (via the open-source connectedhomeip repository), ecosystem platform firmware releases, and device certification before commercial products reach consumer channels.
