Best Smart Plugs with Energy Monitoring
A normal smart plug turns a lamp or charger on and off. An energy-monitoring plug also shows how much power that device draws, so you can spot a charger that never sleeps, compare two appliances, or schedule a heavy load for off-peak hours. This guide explains what to check, then names four currently sold plugs that list energy monitoring: Matter Wi-Fi, HomeKit Wi-Fi, and Thread.
Quick answer
Track what each lamp, charger or appliance actually uses: Matter, HomeKit and Thread plugs with energy monitoring, load limits and honest hub notes.

What to look for in an energy-monitoring plug
- Confirm monitoring is listed. “Smart” does not mean it measures power. Check the maker’s page for energy monitoring, power consumption or similar wording.
- Know which app shows the data. Maker apps usually have the richest charts. Matter control in Alexa, Google Home or Apple Home may show on/off only.
- Match the load. Compare amps and watts on the appliance label with the plug’s maximum. Leave a margin. Do not use indoor smart plugs with portable space heaters.
- 2.4 GHz Wi-Fi. The Wi-Fi picks here are 2.4 GHz only. Turn that band on, or temporarily separate it during setup if your mesh combines bands.
- Hub reality check. Matter needs a Matter controller. Thread also needs a Thread border router. HomeKit remote access needs an Apple home hub.
- Accuracy expectations. Maker pages describe monitoring features; they are not a substitute for a calibrated meter. Use the readings to compare devices and find standby waste, not for utility billing disputes.
How to use energy monitoring
- Plug in one device you care about (a PC, TV, charger strip or dehumidifier), not a whole room full of unknowns.
- Watch real-time watts while the device is on and off so you can see standby draw.
- Leave it for a few days and read daily or weekly totals in the maker’s app.
- Enter your electricity rate if the app offers bill estimates (Tapo and Eve describe this).
- Act on what you find: schedules, auto-off timers or Charge Guard-style cutoffs for chargers that finish overnight.

About these picks: we only link to listings sold new by Amazon.com or the brand’s official store, and the picks are not independently tested. How we pick
Gear worth considering
Each pick is matched to the maker’s model number. Specifications come from TP-Link, Kasa and Eve product pages and the Amazon listings, checked November 6, 2026. We have not tested any of these plugs, and we do not quote prices because they change often. Energy readings can differ by platform: some Matter apps show less detail than the maker’s own app.
Best Matter Wi-Fi pick: Tapo P110M
Choose this when you want Matter plus energy monitoring on ordinary 2.4 GHz Wi-Fi, without adding a Thread border router. TP-Link lists the P110M as Matter-certified for Apple Home, Alexa, Google Assistant and Samsung SmartThings, with energy tracking and bill estimates in the Tapo app once you enter your electricity rate. It also lists Smart Charge Guard (auto-off when power stays below a threshold you set) and power protection that can cut power if the load exceeds a limit you set. Specs: 2.4 GHz Wi-Fi only (Bluetooth for setup), maximum load 15 A / 1800 W at 100–125 V for general or resistive loads (1/6 HP motor), UL94-V0 flame-retardant housing, about 66 × 38 × 40 mm so it is less likely to block the neighboring outlet. No separate hub is needed for Tapo app control; Matter still needs a Matter controller from your chosen platform. The Amazon link below is a 2-pack.

We have not independently tested this product. Availability, specifications and hardware versions can change; confirm the details on the product listing and the manufacturer's site.
Best for Apple HomeKit: Kasa EP25
Pick this when you want native Apple HomeKit support and energy monitoring in the Kasa app, without going through Matter. TP-Link’s Kasa listing describes the EP25 as a HomeKit-supported Wi-Fi mini plug with real-time and historical energy use in the Kasa app, plus Alexa, Google Assistant and SmartThings. Specs from the listing: 15 A / 1800 W max load, 2.4 GHz Wi-Fi only, compact body (about 2.62 × 1.57 × 1.5 in), UL-certified flame-retardant design and a 2-year limited warranty. Setup can use the Kasa app, Amazon Frustration-Free Setup or Google Seamless Setup. HomeKit remote access still needs a home hub such as a HomePod, Apple TV or iPad left at home. The Amazon link below is a 4-pack (EP25P4).

Best Matter pick in the Kasa app: Kasa KP125M
A slim Matter-over-Wi-Fi plug when you already use Kasa, or want Matter with energy history in the Kasa app. TP-Link lists Matter support for Apple Home, Alexa, Google Home and SmartThings, energy monitoring (real-time and historical), and a compact design that avoids blocking adjacent sockets. Specs commonly listed for the US model: 100–120 V, 15 A / 1800 W max for general or resistive loads (1/6 HP motor), 2.4 GHz Wi-Fi, UL-certified flame-retardant design and a 2-year limited warranty. Energy detail is strongest in the Kasa app; TP-Link notes that some platform apps show less (or no) energy data over Matter. The Amazon link below is a 2-pack (KP125MP2).

Best Thread / privacy pick: Eve Energy
Choose Eve when you already have a Thread border router and prefer a plug that does not use Wi-Fi or an Eve cloud account. Eve lists Matter over Thread, local control with no Eve cloud, registration or tracking, and energy monitoring (with projected cost once you enter your rate) in the Eve app on supported platforms. US/Canada specs from Eve: AC 120 V, 60 Hz, max 15 A / 1,800 W; Thread wireless; about 2.8 × 1.5 × 2.4 in; UL-certified; built-in on/off button. As a mains-powered Full Thread Device it can also relay Thread traffic for other accessories. You need a hub that is both a Matter controller and a Thread border router (examples Eve lists include HomePod mini / HomePod 2nd gen / Apple TV 4K 2nd gen or later, Nest Hub 2nd gen / Nest Wifi Pro, several Echo and eero models, and SmartThings Hub v3). Without that hub, Eve Energy cannot join your home.

Frequently asked questions
Do all smart plugs show energy use?
No. Many plugs only switch power on and off. If you want readings, confirm the listing and the maker’s page say energy monitoring, and check which app shows the data. Some Matter plugs report energy only in the maker’s app, not in every voice-assistant app.
Will energy monitoring work in Apple Home or Alexa?
It depends on the plug and the platform. Kasa and Tapo list the richest charts and bill estimates in their own apps. Eve lists energy insights in the Eve app and on some platforms such as SmartThings and Home Assistant. Confirm on the maker’s page for your setup before you buy.
Do I need a hub for these plugs?
The Tapo P110M, Kasa EP25 and Kasa KP125M connect over 2.4 GHz Wi-Fi and need no separate radio hub for their maker apps. Matter features still need a Matter controller. Eve Energy has no Wi-Fi: it needs a Matter controller that is also a Thread border router. See our guide on whether smart plugs need a hub.
What load can these plugs handle?
All four picks list a maximum of about 15 A / 1,800 W for general or resistive loads in the US. That is not a green light for every appliance. Skip portable space heaters, follow the appliance maker’s rules on timers or remote switching, and leave a margin under the plug’s maximum load.
Wi-Fi or Thread: which is better for monitoring?
Neither is automatically better for accuracy. Wi-Fi plugs are simpler if you do not already own a Thread border router. Thread plugs keep traffic off your Wi-Fi and can strengthen a Thread mesh, but they will not set up without the right hub. Pick based on the hub you already have.
Can I use these outdoors?
No. These four are indoor plugs. For holiday lights or a porch outlet, use an outdoor-rated model and see our outdoor smart plugs for Christmas lights guide.
