The Connectivity Standards Alliance just released Matter 1.4 — and it finally makes whole-home energy management seamless with EV charging, solar, and battery storage all in one protocol.
May 02, 2026 | 14 min readBy adding EVSE (Electric Vehicle Supply Equipment), solar panel controllers, and battery storage as native device types, Matter 1.4 transforms from a simple device-control protocol into a complete home energy management platform. If you have an EV, solar panels, or a home battery — this changes everything.
Matter 1.4 is the latest revision of the universal smart home standard developed by the Connectivity Standards Alliance (CSA). While previous versions focused on lights, locks, thermostats, and sensors, Matter 1.4 takes aim at the energy management layer of your home.
The new standard introduces three major device types that bring your home's energy ecosystem into the Matter fold:
Until now, managing a home with solar panels, an EV charger, and a battery meant juggling separate apps from different manufacturers. Your Tesla Wall Connector had its own app. Your Enphase solar system had another. Your Tesla Powerwall or Enphase IQ Battery lived in yet another ecosystem.
Matter 1.4 collapses all of this into a single protocol that works natively across Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings. That means:
The EVSE device type is the headline feature of Matter 1.4. For the first time, EV chargers become first-class smart home citizens with deep automation support:
| Feature | What It Means |
|---|---|
| Charge Scheduling | Set charging windows via your smart home app — charge only during off-peak hours automatically |
| Load Management | Coordinate EV charging with other home loads to avoid exceeding your panel's capacity |
| Bidirectional Charging | Support for V2H (vehicle-to-home) — use your EV battery to power your home during outages or peak pricing |
| Energy Reporting | Real-time and historical energy consumption data for your EV charger |
| State of Charge | Monitor your vehicle's battery level from any Matter-compatible app |
Matter 1.4 doesn't stop at EV charging. Solar panel controllers and battery storage systems join the protocol with rich data and control capabilities:
Solar Panel Controllers expose real-time generation data, per-panel performance metrics (on supported hardware), and enable automations like "when solar generation drops below 500W, reduce non-essential loads."
Battery Storage Systems report charge level, charge/discharge rates, grid import/export, and support scheduling for time-of-use optimization. You can automate: "charge the battery during off-peak hours, discharge during peak hours to save money."
One of the best aspects of Matter 1.4: existing Matter devices benefit too. The enhanced energy reporting framework applies to all device categories, meaning your existing smart plugs, lights, and appliances can now report energy consumption data through the Matter protocol — if the manufacturer enables it via an over-the-air update.
Matter 1.4 also improves the multi-admin experience — the ability to use a single device across multiple ecosystems simultaneously. Device transfer between platforms is now seamless, and you can more easily manage which platforms have access to which devices.
To take advantage of Matter 1.4 energy features, you'll need:
The good news: several manufacturers have already announced firmware updates to bring existing hardware to Matter 1.4 compliance. Check with your device manufacturer for specific timelines.
| Platform | Matter 1.4 Support | Timeline |
|---|---|---|
| Apple Home | Confirmed | iOS 19 / macOS 16 update |
| Google Home | Confirmed | Rolling out now |
| Amazon Alexa | Confirmed | Late 2026 |
| Samsung SmartThings | Confirmed | Available now |
| Home Assistant | Confirmed | Available via update |
Matter 1.4 is the most significant update to the smart home standard since its inception. By bringing energy management into the fold, it addresses the biggest gap in the Matter ecosystem and positions the protocol as the backbone of the modern connected home. If you're building or expanding a smart home with solar, EV, or battery storage, Matter 1.4 makes it possible to manage everything from a single app — regardless of which platform you prefer.
