Quick answer: Buy the Shelly Plug S Gen3 if you care about flexible power-based automations, Home Assistant habits, and a brand that treats energy reporting as core product. Buy a Meross Matter smart plug with energy monitoring if you mainly want quick Apple Home or Google Home Matter pairing with watt/kWh visibility and less tinkering. Both can measure energy; they optimize for different buyer personalities.
This is a practical head-to-head for shoppers who already narrowed to Matter plugs with energy monitoring—especially EU/UK buyers who keep seeing both names on shortlists. It is not a lab shootout. Gadget Clash has not calibrated either plug’s watt accuracy. Confirm the exact regional SKU, max load, and Matter firmware notes on the manufacturer page and on Gadget Clash product listings before you buy.
Quick picks
- Best for Home Assistant / power automations: Shelly Plug S Gen3
- Best for simple Apple Home / Google Home Matter: Meross Matter energy plug

How we chose
We compared buyer-fit criteria from published product positioning—not invented benches:
- Matter onboarding friction into Apple / Google / Alexa / Home Assistant
- Energy monitoring depth (instant watts, history, automations on power)
- Local-control and integration culture
- Physical fit (socket blocking, plug body)
- Electrical limits and regional form factors
- App complexity vs “set and forget”
We did not invent accuracy percentages, reliability scores, or fake kWh charts.

1. Shelly Plug S Gen3 — best when energy data drives automations
Shelly’s Gen3 plug positioning is built around Matter plus detailed power and energy reporting. That matters if your real goal is “start a notification when the dryer finishes” or “chart the PC’s idle draw,” not only “Siri, turn off the lamp.”
Shelly’s wider product culture (web UI habits, MQTT/local options on many devices, strong Home Assistant mindshare) is why power users keep recommending it even when a simpler Matter plug exists. The trade-off is complexity: more settings, more ways to misconfigure, and a body that may block neighboring sockets depending on your wall plate.
Choose it if: you want threshold automations, HA dashboards, and long-term flexibility.
Skip it if: you want the least number of apps and menus between unboxing and “shows watts in Apple Home.”
2. Meross Matter energy plug — best when Matter simplicity wins
Meross Matter energy plugs aim at buyers who already live in Apple Home or Google Home and just want a monitored outlet without becoming a smart-home sysadmin. Pairing via Matter, seeing power/energy in the vendor app (and whatever attributes your controller exposes), and moving on with life is the pitch.
The critical shopping rule: buy the energy monitoring Meross Matter SKU. Meross (like everyone else) also sells simpler plugs. Listing titles on marketplaces are messy—match the model string to the manufacturer energy page.
Choose it if: ecosystem simplicity beats deep local scripting.
Skip it if: you already standardized on Shelly and want one app/integration story for every outlet.
Before you buy
Confirm max load for the appliance
Laundry finish-detection is popular—but dryers and heaters can sit near plug limits. If you are unsure, do not risk it; use a correctly rated circuit solution.
Check the physical socket map
Double wall plates, surge strips, and behind-furniture outlets punish bulky plugs. If the second socket dies the day you install it, you “saved” nothing.
Decide where you will read the energy data
Apple Home / Google Home may not surface the same charts as the vendor app or Home Assistant. If pretty history graphs are the point, verify where those graphs live.
Region and warranty
EU Schuko vs US NEMA vs UK pins are different products. Buy local voltage/current ratings and keep the invoice for warranty.
Firmware and Matter controller maturity
Matter still depends on your hub software. Update the controller first; then commission the plug. If Joint Fabric / multi-admin matters to you, read current platform release notes rather than assuming every 2024 article still applies—see also our Matter 1.6 buyer notes.
Our verdict
Pick Shelly Plug S Gen3 when energy is a feature you will automate, not just glance at. Pick Meross Matter energy when you want Matter monitoring with less ceremony. If neither fits—budget, Thread, or socket size—widen to the Matter energy plugs roundup instead of forcing a bad match.
Which is more accurate?
Neither should be treated as a utility-grade meter without independent calibration. Use them for trends and automations. Gadget Clash has not lab-tested either.
Which is better for Apple Home?
Meross is usually the lower-friction Matter path for Apple-centric homes. Shelly can work via Matter too—confirm current commissioning steps for your iOS/Home version.
Which is better for Home Assistant?
Shelly is the more common power-user recommendation thanks to integration depth. Meross can still work via Matter; expect fewer “Shelly-native” knobs.
Can I mix both brands?
Yes. Many homes do. Pick one “default” brand for sanity if you hate juggling apps—but Matter exists partly so mixing is survivable.
Deeper buyer scenarios
Apartment laundry finish detection
Both plugs can support “notify when power drops” style automations if your app or Home Assistant can read watts. Shelly usually exposes richer threshold tools; Meross may keep more of that logic in its app. Test with a lamp first—never experiment on a high-draw dryer until you confirm electrical limits.
Shared flat political reality
If three roommates share a kitchen, label the plug and agree who gets the app notifications. Smart plugs become relationship issues faster than spec sheets admit.
Travel and second homes
Matter helps when you re-commission into another fabric, but accounts and Wi-Fi still travel with you. For holiday flats, prefer plugs you are willing to leave behind or fully reset.
Extra FAQ
Do these plugs work on extension leads?
Often discouraged or limited by manufacturer guidance. Prefer wall outlets within rating. Daisy-chaining smart plugs is a bad idea.
Can energy data go into Apple’s Home electricity features?
Platform support evolves. Verify what your iOS/Home version surfaces versus what remains vendor-app-only.
What about outdoor sockets?
Only use plugs explicitly rated for outdoor/damp locations. Indoor Matter energy plugs are not patio gear.
