Which Matter Smart Plugs Show Your Energy Use? (UK 2026)

As of mid-2026, the brands publicly confirmed to ship Matter-energy-reporting plugs include TP-Link (the Tapo P110M), Meross (MSS315 UK), Eve Systems (Eve Energy), Ikea, Ledvance and Bosch Smart Home. The list is moving - a plug that was Matter-controllable but did not expose energy data on its launch firmware may pick up the capability via a later update, and a few vendors still ship Matter-but-not-energy variants alongside the full-fat versions.

The single most widely available UK option is the Tapo P110M, a 13A plug with energy monitoring that sells on the official Tapo UK store at around £10-£17 depending on promotion. It is rated to the full 13A typical for a UK domestic socket, which means it will handle everything bar the largest immersion heaters and 3kW kettles at the edge of the limit.

If you already own non-Matter Tapo or Meross plugs - the ones that needed the vendor app - you cannot simply update to Matter. The energy-reporting feature requires the Matter-certified hardware revision; the older models keep their existing app-only energy graphs and that is the end of the line for them.

The Electrical Power Measurement cluster (the part of Matter that handles instantaneous readings) exposes 19 attributes, but the three that matter for everyday use are active power in milliwatts, voltage in millivolts and current in milliamps. Your hub almost certainly converts these into the familiar units before showing them, so the on-screen readout reads as "1,500 W" rather than "1500000 mW".

The Electrical Energy Measurement cluster handles the running total. Smart plugs that support it report cumulative consumption in kilowatt-hours since the meter was last reset, plus a few related accumulators. A handful of plugs - Bosch and TP-Link among them - also report energy fed back into the plug as a separate value, which is more useful for sub-metering a battery or solar diverter than for a standard appliance.

What you will not see is sub-second resolution. Matter is a control protocol, not an oscilloscope; the standard expects readings to update every few seconds at best, which is plenty for spotting that the dishwasher is on but not enough for waveform analysis. If you are trying to track motor inrush or rapid switching, you still need a dedicated whole-house energy monitor.

Apple Home, Google Home and Samsung SmartThings all added Matter 1.3 support during 2025; for most users running an up-to-date HomePod, Google Nest Hub or SmartThings Hub, energy readings flow through automatically once the plug is commissioned. The visualisation varies - Apple shows a per-accessory tile, Google has a dedicated Energy section in the Home app, and SmartThings surfaces the data in its Energy view alongside any compatible appliances.

Home Assistant - the open-source platform popular with self-hosters - needs at least version 2024.10 and Matter Server 6.x for the energy entities to appear. That is achievable for anyone running a recent Home Assistant Green, Yellow or DIY install; older long-term support builds will not see the new attributes until they upgrade. We have a separate walkthrough on setting up the Home Assistant Energy Dashboard with UK SMETS2 meters that pairs nicely with Matter plug data.

The choice of platform mostly affects how you see the data, not whether you see it - the plug reports the same numbers to all of them. The real-world reason to favour one ecosystem over another is automation, not metering: Google's Routines, Apple's Shortcuts, SmartThings Automations and Home Assistant's Automations each handle "if device exceeds 1500 W, send notification" differently.

For most UK households, the honest answer is: only on the appliances you actually wonder about. The standing power of an LED lamp or a router is not going to change your bill; the dishwasher cycle, the freezer compressor, the tumble dryer and the immersion heater are where per-appliance monitoring earns its keep. Sticking a Matter-energy plug on each of those four is a £40-£70 investment that pays back the first time you spot a freezer with a failing door seal.

The wider play is the one the CSA itself has been pushing: connecting per-appliance data into a broader energy management system that can also see your solar generation, your battery state and your tariff. We have written separately about how Matter and OpenADR aim to bring grid-friendly pricing into the home, and that is the direction the standard is travelling. Today's plug data is the foundation that future demand-response automations will be built on.

If you already own a SMETS2 smart meter, the whole-house picture is covered by the in-home display or by Hildebrand-style integrations. Matter plugs answer the next question: which appliance inside the house is responsible for that spike. The two views complement each other; neither replaces the other.
