Matter for energy, and the platforms that ignore it

What Matter defines, by release#

One correction first, because it is repeated constantly: EV chargers and device energy management arrived in Matter 1.3, not 1.4. The 1.4 release is the one that added the generation and storage side.

Underneath the device types sit two ideas worth understanding, because they explain what a good implementation should let you do.

Measurement is the simple half. Electrical measurement clusters let a device report instantaneous power and cumulative energy. This is what a Matter smart plug uses when it shows watts, and the accuracy question is covered in smart plugs and energy monitoring.

Management is the interesting half. Device energy management lets a device describe its expected consumption and accept requests to shift, pause or reduce it. That is the machinery behind "charge the car when power is cheap" or "pause the water heater during a grid peak", expressed as a standard rather than as a vendor cloud feature. With the 1.5 tariff and carbon intensity data, the price and emissions signal that drives those decisions can also travel over Matter instead of through an integration your platform had to build itself.

Bidirectional EV charging in 1.5 extends the same model to sending energy back, which is the specification catching up with vehicle-to-home hardware rather than leading it.

Who actually exposes it#

Two rows from our gap tracker say most of it. The energy device types are among the oldest unshipped features in Matter.

Apple Home has no energy monitoring of any kind. Not for Matter energy device types, not for plugs, not as a dashboard. A Matter EV charger paired to Apple Home is, at best, a switch.

Google Home documents device types topping out at Matter 1.3 and was still adding 1.2 appliance types as late as September 2025. Energy is not in its supported list, and Google Home has no user-facing energy dashboard built on Matter.

Alexa runs the Matter 1.5 SDK on Echo devices and exposes a subset of device types, mapped onto cloud-side capability interfaces. There is no evidence of user-facing Matter energy management on Alexa.

Where it does work:

• SmartThings shipped Matter 1.5 about a month after the specification, the fastest of the mainstream platforms, and exposes the energy device types.
• Home Assistant runs the most current Matter implementation of any platform, with Matter 1.5.1 in Matter Server 9.0 (June 2026) and Matter 1.6 in 9.1.0 (July 2026), and it already has a mature energy dashboard for the data to land in.
• Homey Pro certified Matter 1.5 in June 2026 across its current hardware, which brings the energy device types into scope. Cameras were explicitly excluded from that certification; energy was not.

Why the big three are missing#

It is worth being precise about the reason, because it changes how long you should expect to wait.

Energy management is not a small feature to add. It needs a UI concept that does not exist in Apple Home, Google Home or the Alexa app: a place to show consumption over time, a way to express a price or emissions signal, and a scheduling model that can shift a load rather than just switch it. Those platforms have optimized for a tile you tap.

There is also a business reason. Utility programs, demand response and time-of-use optimization are products in their own right, and the platform vendors sell or partner around them separately. A neutral standard that lets any charger talk to any controller is not obviously in their interest.

The result is the widest specification-to-shipping gap in Matter: EV chargers have been standardized since May 2024 and three of the five biggest consumer controllers still show nothing. That is worse than the appliance lag, where Google shipped Matter 1.2 types about 23 months late.

What to buy today if you care about energy#

Concretely: if you want solar production, battery state of charge, and EV charging in one automation today, that is a Home Assistant project using native integrations, with Matter as an on-ramp for whichever pieces support it. The hardware-level guidance is in solar, batteries and EV charging, and heat pumps and what Matter exposes for HVAC covers the heating side.

What to watch next#

Three signals, in order of usefulness:

1. Any of the big three documenting an energy device type. That would be the first evidence the category has a mainstream market. Nothing suggests it is imminent.
2. Certified hardware volume. Standardizing a device type does not create products. Certified EV chargers, inverters and battery systems remain thin compared to the lighting and sensor categories.
3. Tariff data in a shipping controller. The 1.5 tariff and carbon intensity clusters are the piece with the highest practical value, because they remove the need for every platform to build its own price feed. Watch Home Assistant and SmartThings first, since they ship Matter releases fastest.

The current state per controller is tracked at Matter feature gaps, and what each release contained is in every Matter version.
