Device makers can now certify home routers and access points that bundle a Wi-Fi access point with a Thread Border Router, a change the Connectivity Standards Alliance says will cut the number of separate Thread networks a single household runs.
The Matter 1.4 specification, released in November and now available for integration, also adds Enhanced Multi-Admin, expanded energy management, and two new device types for in-wall switches. For a standard barely two years old, it's a dense release.
Why this matters now: Matter already sits in millions of homes, but anyone who has tried running two Thread border routers from different vendors knows the fragmentation problem. Home Routers and Access Points, or HRAP as the Alliance calls them, are meant to be that one device every connected home already has. The stakes are practical. If 1.4 lands well, the next decade of smart home gear shares one mesh instead of a tangle of vendor corners.
The Fragmentation Problem HRAP Solves
Before Matter 1.4, a Thread device added through a Google-branded mesh could sit on a separate network from one added through an Apple TV hub. That duplication meant duplicated traffic, shorter battery life for low-power sensors, and a troubleshooting maze when something dropped offline. HRAP devices store Thread credentials in a secure directory and share them with new border routers so the mesh stays unified.
According to the Connectivity Standards Alliance, manufacturers can now design or upgrade routers and set-top boxes to act as that shared foundation, covering both Wi-Fi and Thread devices on the same hardware. The Alliance notes the HRAP roadmap will continue to add enhancements, including support for improvements coming in Thread 1.4. The version numbers of Matter 1.4 and Thread 1.4 are coincidental and unrelated, the Alliance is careful to point out.
It's not automatic that vendors will ship this on existing routers. Pushing firmware updates to millions of installed devices is a real engineering and support cost, and some makers will limit HRAP to new hardware. The standard allows it; the market decides.
Enhanced Multi-Admin, Finally Optional
Multi-Admin is central to Matter's vision of choice and interoperability, allowing users to connect Matter devices to multiple smart home systems. Sharing each device individually when managing multiple platforms becomes tedious and complex as the home expands. Enhanced Multi-Admin makes smart home management easier with single user consent, enabling existing and new devices to connect to multiple ecosystems automatically.
Matter 1.4 and future releases provide developers with flexible approaches to implement this optional experience based on their applications. Following the release, the Alliance said it will publish more in-depth blog posts on how HRAP and Enhanced Multi-Admin functions work and how product makers can choose the path that best fits their applications.
It's not obvious Enhanced Multi-Admin will land evenly. The Alliance leaves implementation flexible, which means two platforms may behave differently even when both claim support. Users checking compatibility lists should verify the feature specifically, not rely on the Matter 1.4 badge alone.
Energy Management Becomes the Headline Feature
Home energy management is emerging as one of the top reasons consumers adopt smart home gear, according to research from Parks Associates cited by the Alliance. Matter 1.3 introduced energy reporting for large appliances and EV chargers. Matter 1.4 makes energy a first-class feature across the home.
New energy device types include solar inverters and panel arrays, including hybrid solar and battery systems, plus battery walls and Battery Energy Storage Systems that can discharge back into the home or grid to create what the Alliance calls virtual power plants. Heat pumps gain forecasting and scheduling so usage can shift to off-peak periods, and some units include a buffer tank that acts like a battery. Electric water heaters now support preset temperatures, hot water level monitoring, scheduled heating, and a boost command for rapid heating when guests arrive.
EV chargers gain user-defined charging preferences, letting owners specify when their car should finish charging. Thermostats add scheduling and preset modes like vacation and home or away, triggerable via motion detection or calendar events. A new Device Energy Management mode lets controllers choose between device-level, local, or grid-wide optimization. Water heaters also get a mode cluster for toggling scheduling on and off.
Occupancy sensing expands to support radar, vision, and ambient technologies, with customizable sensitivity and event-based history reporting. The Alliance frames this as groundwork for person detection and activity classification in future releases.
New Device Types and Battery Gains
For in-wall hardware, Matter 1.4 adds two device types for fixed load control: mounted on and off switches, and mounted dimmable switches. Previously these were typically modeled as lights, which limited how apps and automations treated them. Modeling them as switches should make automations more accurate, since the controller now knows it is commanding a switch rather than a lamp.
Battery-powered devices get their own treatment. The Long Idle Time protocol extends battery life for intermittently connected devices, including switches, buttons, and sensors. A new Check-In Protocol keeps communication reliable for low-power hardware that needs it, and quieter reporting of predictable attribute changes cuts network traffic.
Mounting all of this on a single specification took roughly two years of deployment data from millions of households, plus the work of thousands of engineers across member companies, by the Alliance's account. That experience base is what makes 1.4 feel less like a maintenance release and more like a structural upgrade.
Suppliers interested in building to the spec can download it from the Connectivity Standards Alliance and pull the Matter 1.4 SDK from the Project CHIP repository on GitHub. Certification testing follows the updated test plan. The Alliance's original announcement covers each cluster in more detail.

The real test comes in the next twelve months, when manufacturers decide whether to ship HRAP firmware to devices already in living rooms, and whether Enhanced Multi-Admin behaves consistently across competing ecosystems. If those two pieces hold, Matter stops being a pairing protocol and becomes the network layer it was always meant to be. If they don't, the standard risks reverting to the very fragmentation it was designed to solve.
