A new energy management device from the Australian firm Safiery has been certified by the Connectivity Standards Alliance (CSA), likely becoming the first product in the ecosystem to include a cluster for Electric Vehicle Supply Equipment (EVSE).
The device, named the STAR-Rover, was certified on October 29. Its appearance is a significant development for the Matter smart home standard. Energy management was a headline feature of the Matter 1.3 release, but despite market anticipation, the adoption of specialized devices like solar inverters, batteries, and EV chargers has been slow. This certification marks the first sign of these advanced energy features arriving in a real-world product.
A specialized switch for off-grid power
Safiery is a company that specializes in state-of-the-art lithium batteries and advanced solar solutions for the RV (recreational vehicle) and marine markets. The STAR-Rover is not a typical consumer smart plug, but a professional-grade digital switching system designed for these 12V or 24V mobile environments.
The device is a 4-channel, 15A controller (with a 40A total continuous power limit) that provides “fuseless” protection for lighting and other devices using advanced MOSFETs. Its primary function is to replace traditional fuse and breaker panels in RVs and boats, offering features like dimming and high-speed short circuit protection (rated at 80 millionths of a second).
STAR-Rover is designed to integrate deeply with other professional off-grid systems, specifically Victron Energy systems, and can be controlled via Controller Area Network (CAN) bus keypads and other non-Matter switches.
“composed plug” with Matter 1.4
The STAR-Rover is certified for Matter 1.4 using Wi-Fi and Bluetooth for connectivity. The way the STAR-Rover integrates Matter is notable. According to its certification file, the device’s primary device type is a “Dimmable Plug-in Unit” (ID 0x010B). This means that to a basic Matter controller, it will likely just appear as four dimmable lights.
However, the certification confirms the device is a “composed” product. Alongside its basic dimmer function, it also includes multiple voltage and current sensors for power management and a complete EVSE set of clusters. This makes it a hybrid device. While a simple Matter controller will only see the “plug” part, an advanced controller or energy management dashboard that supports the full Matter 1.4 energy spec could, in theory, recognize and interact with the EVSE functions for managing vehicle charging.
The practical use of this new EVSE cluster is currently limited by platform support. Among the big four Matter platforms, only Samsung SmartThings has officially announced support for the advanced energy management device types, including EVSE. The open-source platform Home Assistant may also have partial support, but it remains largely untested, as there have been no devices on the market to test with until now.
While this is a highly specialized product for a niche market, its certification is a key first step in paving the way for more mainstream Matter-enabled EV chargers and energy management systems.
