The best smart plugs for energy monitoring do more than turn a lamp on and off with your voice. They tell you exactly how many watts a device is pulling right now, and how that adds up over a day, a week, or a month, so you can find the appliances quietly running up your electric bill.
We compared the most popular energy-monitoring plugs on tracking accuracy, app usability, and voice assistant support, then checked those specs against patterns in verified customer reviews. A few plugs clearly do this better than the rest.
How We Picked
We compared official specifications, energy-monitoring accuracy claims, and manufacturer documentation for each plug, then weighed that against recurring themes in verified Amazon customer reviews, especially complaints about inaccurate readings, laggy apps, or plugs that drop offline. Our picks reflect that research, not paid placement.

1. Kasa Smart Plug Mini KP115: Best Overall
The Kasa KP115 is the plug we point most people to first. It’s been on the market for years, which means a long track record of owners reporting that its energy readings line up closely with what a dedicated power meter shows.
Tracking and App Experience
The Kasa app breaks down usage by day, week, and month, and lets you enter your local electricity rate so it can estimate what a plugged-in device actually costs to run. That turns a vague “the fridge in the garage feels expensive” into an actual number.
It’s also compact enough that it won’t block the second outlet on a wall plate, and it connects directly to Alexa, Google Home, and SmartThings without a hub. With a track record of tens of thousands of positive reviews, it’s the safest first buy if you’re new to energy monitoring.
Kasa Smart Plug Mini KP115
- Real-time and historical energy monitoring in the Kasa app
- Works with Alexa, Google Home, and SmartThings
- Compact design leaves the second outlet free
- Scheduling, timers, and away mode built in

2. TP-Link Tapo P115: Best Budget
The Tapo P115 comes from TP-Link, the same company behind Kasa, and it brings energy monitoring down to a lower price point, especially since it’s commonly sold in a 2-pack.
The app shows the same kind of daily, weekly, and monthly usage charts as the Kasa line, and it connects to Alexa, Google Home, and Samsung SmartThings. You give up a little brand polish compared to Kasa, but for tracking two or three appliances around the house without spending much, it’s a strong value.
TP-Link Tapo P115 Smart Plug
- Energy monitoring with daily, weekly, and monthly usage charts
- Works with Alexa, Google Home, and Samsung SmartThings
- Sold in a 2-pack, so per-plug cost stays low
- Compact mini design, ETL certified

3. Eve Energy (Matter): Best for Apple Home
The Eve Energy is the pick for anyone who wants energy monitoring without routing everything through a manufacturer’s cloud. It runs on Matter over Thread, works locally, and integrates cleanly with Apple Home, Alexa, Google Home, and SmartThings.
Its built-in power meter tracks consumption right in the Eve app, and because it’s Thread-based, response times tend to be faster than cloud-dependent Wi-Fi plugs. You’ll want a Thread border router, which most recent Echo and Nest speakers already provide, and it costs more than the Wi-Fi options here. For privacy-minded Apple households, it’s worth the premium.
Eve Energy (Matter)
- Matter over Thread, runs locally with no manufacturer cloud
- Works with Apple Home, Alexa, Google Home, and SmartThings
- Built-in power meter tracks consumption in the Eve app
- No hub required beyond a Thread border router

4. SwitchBot Plug Mini: Best Multi-Platform
The SwitchBot Plug Mini earns its spot by working smoothly across ecosystems, Alexa, Google Assistant, and Home Assistant, while still packing in energy monitoring that refreshes close to real time.
It connects over both Wi-Fi and Bluetooth, so it keeps working locally even if your internet has a hiccup with cloud features. Its compact shape also keeps the neighboring outlet free. If you’re mixing smart home platforms and want one plug that plays nice with all of them, this is a solid, newer option worth watching for long-term reliability data.
SwitchBot Plug Mini
- 15A energy monitoring updates that refresh in near real time
- Works with Alexa, Google Assistant, and Home Assistant
- Wi-Fi and Bluetooth, no separate hub needed
- Compact footprint keeps the second outlet clear

5. Meross Matter Smart Plug with Energy Monitor: Best for Google Home
Meross’s Matter-certified plug rounds out this list as a budget-friendly way to get energy monitoring on a Matter device. It works with Apple Home, Alexa, and Google Home, and handles up to 15A/1800W.
Energy readings live in the Meross app, since Matter itself doesn’t carry that data yet, but setup through Google Home is notably straightforward according to owner feedback. It’s a reasonable middle ground if you want Matter’s easy multi-platform pairing without paying Eve Energy prices.
Meross Matter Smart Plug with Energy Monitor
- Matter-certified, works with Apple Home, Alexa, and Google Home
- Energy monitoring tracked in the Meross app
- 15A / 1800W max load rating
- App and voice control with schedules and timers

Pros
- See exactly how many watts a device draws, in real time and over time
- Spot phantom loads like old chargers, game consoles, and space heaters
- Most models pair with Alexa or Google Home for voice control on top of tracking
- Historical data in the app helps you estimate what a device actually costs to run
Cons
- Cost estimates are only as accurate as the electricity rate you enter in the app
- Cloud-connected models lose remote monitoring if your internet drops
- Matter currently doesn't carry energy data, so you still need the maker's own app for readings
How to Choose a Smart Plug for Energy Monitoring
A few details separate a plug that actually helps you save money from one that just sits there logging numbers nobody checks.
Decide if you need real-time data or just trends. Some plugs update wattage readings almost instantly, useful for testing one appliance at a time. Others are better suited to long-term trend charts. Most buyers only need the latter.
Check the app, not just the plug. The hardware is similar across brands. What differs is whether the app makes usage data easy to read, lets you set your electricity rate, and sends useful alerts. Read a few recent reviews focused on the app before buying.
Think about your ecosystem. If you’re deep in Apple Home, the Eve Energy’s local Matter-over-Thread design is the more private, faster option. If you mainly use Alexa or Google Home, a Wi-Fi plug like the Kasa KP115 or Tapo P115 is simpler and cheaper.
Remember Matter doesn’t carry energy data yet. Don’t assume a Matter badge means you’ll see wattage in your Matter controller’s app. For now, energy readings still live in each plug maker’s own app.
Our Verdict
For most people, the Kasa Smart Plug Mini KP115 is the best smart plug for energy monitoring in 2026. It combines dependable, closely-tracked wattage data with a low price and simple setup across Alexa and Google Home, backed by a long history of positive owner feedback.
If you want to save a bit more per plug, the Tapo P115 delivers nearly the same experience in a 2-pack. If local control and Apple Home integration matter more than price, spend up on the Eve Energy. And if you’re mixing smart home platforms, the SwitchBot Plug Mini is worth a look.
Whichever you choose, an energy-monitoring plug pays for itself the moment it flags one wasteful appliance. Check the latest price on Amazon before you buy, these plugs go on sale often. Also check out our guides to the best budget smart plugs and smart thermostat for renters.
