The short list, by what you need
Our starting pick is the Tapo P110M for its energy reports and two-pack option. Kasa suits an existing Kasa setup; Eve suits a home with the required Thread hub. These are use-case recommendations based on specifications, not a measured accuracy ranking.
| Model | Best fit | Key details | Watch for |
|---|---|---|---|
 | Starting with Wi-Fi energy monitoring | Connection: 2.4 GHz Wi-Fi + Matter Rated voltage: 100–125V AC, 50/60Hz | Requires a 2.4 GHz Wi-Fi network. |
 | An existing Kasa setup with several devices | Connection: 2.4 GHz Wi-Fi + Matter Rated voltage: 100–120V AC, 50/60Hz | The linked listing is a four-pack, not one plug. |
 | A home already equipped for Thread | Connection: Matter over Thread US electrical rating: 120V AC, 60Hz; max. 15A / 1800W | Needs a compatible Matter controller and Thread border router. |

PICK 01 · Starting with Wi-Fi energy monitoring
TP-Link Tapo P110M
Our first choice to investigate for a small measurement project using the Tapo app.
- Connection
- 2.4 GHz Wi-Fi + Matter
- Rated voltage
- 100–125V AC, 50/60Hz
- Maximum load
- 15A / 1800W general use; 1/6 HP motor
- Energy view
- Tapo app; other apps vary
The P110M combines energy tracking, an electricity-rate input and scheduling in the Tapo app. It uses 2.4 GHz Wi-Fi. That makes it a practical starting point if your question is about a lamp or desk device and you do not already have a Thread network. The linked listing is a two-pack; check that the selected option still says P110M.
Matter support is useful for controlling the plug in other smart-home systems, but energy reporting needs a closer look. TP-Link’s firmware 1.3.2 release notes for US hardware V1.6 added Matter 1.3 energy reporting and explicitly warn that app support varies. Update your plug using the firmware for its exact hardware version and confirm that your chosen app shows the readings you need. The Tapo app is the clearest documented starting route.
We would choose this over the Kasa four-pack for a smaller first experiment. That is a purchase-size judgment, not proof that Tapo measures more accurately. Measure normal use before adding schedules, and only switch equipment off when doing so is appropriate.
Why consider it
- Energy tracking and bill estimates in the Tapo app.
- Matter control alongside the manufacturer’s app.
- The linked two-pack keeps an initial trial smaller than a four-pack.
What to check
- Requires a 2.4 GHz Wi-Fi network.
- Energy reporting in other Matter apps depends on firmware and platform support.
- 15A/1800W is the general-use/resistive limit; other load types have different limits.

PICK 02 · An existing Kasa setup with several devices
TP-Link Kasa KP125M
A sensible fit when you already use Kasa and have a clear job for four plugs.
- Connection
- 2.4 GHz Wi-Fi + Matter
- Rated voltage
- 100–120V AC, 50/60Hz
- Maximum load
- 15A / 1800W general use or resistive
- Energy view
- Kasa app; verify third-party features
Kasa’s KP125M offers live and historical power information, schedules and Matter control. Its US datasheet lists a Kasa app/account setup and a 2.4 GHz Wi-Fi requirement. If you already use that app, staying with it may be more useful than adding another dashboard. You still need to confirm the exact features available in any third-party app.
The Amazon option linked here is the KP125MP4 four-pack. That is worth noticing before comparing it with the Tapo two-pack or a single Eve plug. Compare cost per plug at checkout, but also count how many devices you actually want to measure. An unused bargain plug does not help answer an electricity question.
Choose this for continuity and quantity, not because Matter guarantees identical energy views everywhere. The manufacturer’s Matter setup instructions call for a supported controller and matching smart-home app. For a one-time reading on one appliance, a simpler plug-in meter may be enough; you do not have to commit to a connected-home system.
Why consider it
- Real-time and historical monitoring through Kasa.
- Matter control for compatible ecosystems.
- Four individually usable plugs for a planned multi-device setup.
What to check
- The linked listing is a four-pack, not one plug.
- Kasa app setup requires an account and 2.4 GHz Wi-Fi.
- Do not assume another Matter app exposes the same energy history.

PICK 03 · A home already equipped for Thread
Eve Energy (Matter)
Consider Eve when you have the right hub and want a Matter-over-Thread plug.
- Connection
- Matter over Thread
- US electrical rating
- 120V AC, 60Hz; max. 15A / 1800W
- Hub requirement
- Matter controller + Thread border router
- US Matter product
- 10EBU4151; model 20EBU4101
Eve Energy uses Thread rather than joining your Wi-Fi network directly. Eve requires a compatible Matter controller and Thread border router, which may be combined in one hub. Check the manufacturer’s hub list before ordering. The cost of a missing hub changes this buying decision.
Eve’s current documentation describes its app on iPhone and iPad with Apple Home, and on Android with Google Home. It also identifies energy management in SmartThings and Home Assistant. Check the current feature matrix for your platform instead of assuming that app/voice control includes every energy feature.
Choose the US Matter version deliberately. Eve identifies it as product 10EBU4151, model 20EBU4101. Older HomeKit stock and European versions are different purchase options. We would pick Eve for an existing compatible Thread setup, not buy a new hub solely on an unproven promise of lower electricity bills.
Why consider it
- Matter over Thread offers a different network choice from the Wi-Fi plugs.
- Energy features are documented for specific app/platform combinations.
- Manufacturer publishes a compatible-hub guide and model identifier list.
What to check
- Needs a compatible Matter controller and Thread border router.
- App and energy features vary by platform.
- Check US version and Matter packaging; avoid confusing it with older or European stock.

Check the job, the load and the app before buying
Write down what you want to learn: overnight desk use, the cost of running a lamp, or how two settings compare. A live watt reading answers a momentary question. A kWh total over a normal day answers an energy-use question. Make sure the app gives you the second number if running cost is your goal.
A 15-amp label is not permission to connect every appliance drawing less than 15 amps. Motors, heaters and other loads can have separate restrictions. Check both manuals and the exact hardware version. Keep these plug-in products within their intended indoor use; do not use them as an improvised way to control essential or hardwired equipment.
Compare the total purchase you need: plug count, any required hub and the value of the information. No plug here automatically saves money. Start with a baseline, make one suitable change, and measure again. For a one-off check, borrowing or buying a standalone meter may be the more practical choice.
For compatible plug-in equipment, follow our appliance measurement steps. To estimate energy charges, use the electricity cost calculator; it is not a UPS runtime calculator.
How we chose these products
We compared manufacturer documentation for the exact US models and matched each to an Amazon.com product listing. Our selection favors clear energy reporting, a useful fit for a specific home setup, and an identifiable US version. We did not buy or bench-test these plugs, so we do not rank measurement accuracy, radio reliability or long-term durability.
The shortlist contains three choices, not every available plug. Tapo and Kasa are both TP-Link brands; their main distinction here is the app and purchase format. Eve adds a different network approach. We leave out prices, star ratings and claimed payback periods because they would not be a stable or independently measured basis for this comparison.
“Best” means our preferred fit for the stated use among this shortlist. It does not claim a complete market test. See our editorial approach for how we handle sources and affiliate links.
