The Kasa Matter KP125M is my best overall pick for smart plugs with energy monitoring because it combines power tracking with Matter support. The Tapo P115 stands out for flexible multipack choices, while Emporia’s four-pack suits households that want to monitor several appliances together. The main tradeoffs are whether you need a hub, which smart home platforms you use, and how many outlets you want to equip at once. Monitoring features and app support also vary, so a multipack is not automatically the best fit. Read on for the full breakdown and recommendations by buyer type.

More Details on Our Top Picks
THIRDREALITY Smart Plug Gen3, 4-Pack
The THIRDREALITY Gen3 makes the most sense for buyers who already use a Zigbee hub and want energy readings across several appliances. Its stated ±1% monitoring accuracy gives it a clearer measurement claim than the Tapo P115, though real-world results can still depend on the connected device and setup. Each plug also repeats the Zigbee signal, so adding outlets can help extend mesh coverage. That combination gives this four-pack a role beyond remote switching.
The tradeoff is the hub requirement: unlike the Wi-Fi Govee Smart Plug, it is not a straightforward choice for a home without compatible Zigbee gear. Power restoration settings also depend on the platform. I’d choose it for an established Home Assistant, SmartThings, or Hubitat setup; buyers seeking a simple app-first plug should look at Tapo instead.
Pros:- States ±1% power monitoring accuracy
- Zigbee repeater function can extend mesh coverage
- Supports several platforms, including ZHA, Z2M, SmartThings, and Hubitat
- Compact form is designed to leave adjacent sockets accessible
Cons:- Requires a compatible Zigbee hub
- Power restoration settings are available only on certain platforms
Best for: Home Assistant, SmartThings, or Hubitat users who want measured appliance use and added Zigbee mesh coverage across multiple outlets
Not ideal for: Buyers without a compatible Zigbee hub or those who want a plug that works directly over Wi-Fi
- Pack size:4
- Connectivity:Zigbee 3.0
- Operating voltage:110 V
- Monitoring accuracy:±1%
- Operation mode:On-Off
- Hub required:Yes
- Control methods:Remote and voice
- Compatible platforms:Home Assistant (ZHA and Z2M), SmartThings, Hubitat, compatible Echo devices, and others
Our verdict“Choose this four-pack if your Zigbee hub is already in place and you value stated monitoring accuracy plus mesh extension.”
Tapo Smart Plug Wi-Fi, Energy Monitoring, P115 (2-Pack), 15A
The Tapo P115 two-pack suits someone who wants to monitor a couple of appliances without committing to a larger set. It combines Wi-Fi energy tracking with scheduling, remote app control, and auto-shutoff, giving it more day-to-day management tools than the Emporia four-pack, whose listed load limit is lower. Alexa and Google Assistant support also makes voice control accessible in many homes.
The smaller pack is its main distinction: it covers fewer outlets than the four-plug Tapo P115, but can be a sensible first step for a few high-interest devices. It depends on Wi-Fi for full functionality and is rated for 15 A maximum, so check the appliance’s requirements before use. Setup may also take more effort than buyers expect. I’d skip it if you want Zigbee mesh support or a larger batch of monitored outlets.
Pros:- Energy statistics and charts help compare appliance use over time
- Works with Alexa and Google Assistant
- Scheduling and auto-shutoff support routine control
- Remote control is available through the Tapo app
Cons:- Full functionality depends on a Wi-Fi connection
- Limited to a 15 A maximum current
- Setup may be complex for some buyers
Best for: First-time smart plug buyers who want to track and schedule two appliances using Alexa or Google Assistant
Not ideal for: Households outfitting many outlets at once or buyers who need a Zigbee-based setup independent of Wi-Fi
- Pack size:2
- Connectivity:Wi-Fi
- Energy monitoring:Yes
- Maximum current:15 A
- Voice control:Alexa and Google Assistant
- Remote control:Tapo app
- Additional controls:Scheduling and auto-shutoff
Our verdict“Pick the two-pack to start monitoring a couple of appliances with app, voice, and scheduling controls.”
Govee Smart Plug with Energy Monitoring (4 Pack)
The Govee four-pack is a practical match for buyers who want to monitor and control several appliances from one Wi-Fi-based setup. It offers real-time energy monitoring, scheduling, and group control, which makes it easier to manage a set of devices together than the two-plug Tapo P115. App, touch, and voice controls add flexibility, with Alexa and Google Assistant compatibility for voice routines.
Its stated 1800 W capacity is useful context for appliance selection, but the plugs are limited to 120 V outlets and do not support 5 GHz Wi-Fi. Unlike the THIRDREALITY Zigbee set, Govee does not extend a Zigbee mesh and needs app setup plus Wi-Fi. I’d shortlist it for grouped household devices on a compatible network; buyers who need hub-based automation or 5 GHz connectivity should look elsewhere.
Pros:- Four plugs support monitoring multiple appliances
- Group control and scheduling simplify routine management
- Supports app, touch, and voice control
- Lists 1800 W capacity and fire-resistant materials
Cons:- Does not support 5 GHz Wi-Fi networks
- Requires app setup and Wi-Fi connectivity
- Limited to 120 V outlets
Best for: Households with several 120 V appliances that they want to monitor, schedule, and control as a group
Not ideal for: Buyers whose Wi-Fi setup relies on 5 GHz, or who need Zigbee hub integration or outlets outside 120 V
- Pack size:4
- Operating voltage:120 V
- Wattage:1800 W
- Connectivity:Wi-Fi and Bluetooth
- Control methods:App, touch, and voice
- Voice assistants:Alexa and Google Assistant
- Dimensions:2.68 × 2.4 × 1.5 inches
- Certifications:ETL, FCC, CA65
Our verdict“Choose Govee if you want a four-plug Wi-Fi set with group control for compatible 120 V appliances.”
Emporia Energy Monitoring Smart Plug, Wi-Fi, 4-Pack
The Emporia four-pack fits buyers who want energy monitoring and scheduled control for lights or other lower-load devices. It covers four outlets and supports remote, app, touch, voice, and push-button control, while Alexa and Google Assistant integration makes it comparable to the Tapo and Govee Wi-Fi options for basic household routines. A listed 1200 W rating gives buyers a concrete limit to check against their appliances.
That capacity is the key tradeoff: its 10 A continuous-load limit is below the 15 A Tapo P115 and makes Emporia less suitable for higher-draw devices. It also needs a 2.4 GHz Wi-Fi network, with no 5 GHz support. I’d pick it for lower-load devices where four monitored outlets matter more than higher current capacity; buyers tracking demanding appliances should compare the Tapo or Govee ratings first.
Pros:- Four plugs provide coverage for several devices
- Monitors energy use and supports scheduling
- Offers app, remote, touch, voice, and push-button controls
- Works with Alexa and Google Assistant
Cons:- 10 A continuous-load limit is lower than the Tapo P115’s 15 A rating
- Requires 2.4 GHz Wi-Fi and does not support 5 GHz
Best for: Buyers who want to monitor and schedule four lights or other lower-load devices over 2.4 GHz Wi-Fi
Not ideal for: People monitoring higher-draw appliances that may exceed the 10 A continuous-load limit
- Pack size:4
- Operating voltage:120 V
- Wattage:1200 W
- Continuous load:10 A
- Connectivity:2.4 GHz Wi-Fi
- Control methods:App, remote, touch, voice, and push button
- Compatible assistants:Amazon Alexa and Google Assistant
- Operating temperature:14–140 °F
Our verdict“Choose Emporia for four lower-load devices when its 10 A continuous limit fits your appliances.”
Tapo Smart Plug Wi-Fi, Energy Monitoring, P115 (4-Pack), 15A
The Tapo P115 four-pack is the better fit when you already know which appliances you want to track across several rooms. It carries the same 15 A current rating, energy monitoring, scheduling, voice control, and auto-shutoff described for the two-pack, but supplies twice as many plugs. Compared with the Govee four-pack, the supplied data emphasizes Tapo’s auto-shutoff and compatibility with Alexa and Google Assistant, while Govee lists group control and Bluetooth alongside Wi-Fi.
This is still a Wi-Fi-dependent option, and its smart home compatibility is limited to supported ecosystems. The available product details do not specify monitoring accuracy or a voltage rating, so buyers comparing precise measurement claims should favor products with those figures stated. I’d choose this set for broad household coverage with familiar app and voice controls, provided your network and appliances fit its requirements.
Pros:- Four plugs cover more devices than the two-pack Tapo P115
- Energy monitoring supports power-use tracking
- Scheduling and remote app control support everyday routines
- Auto-shutoff and voice control are included
Cons:- Operation depends on Wi-Fi
- Compatibility is limited to supported smart home ecosystems
- Product data does not state monitoring accuracy or operating voltage
Best for: Households that want to monitor several appliances in different rooms and use Alexa or Google Assistant
Not ideal for: Buyers who need stated monitoring accuracy, Zigbee hub operation, or compatibility beyond supported Wi-Fi ecosystems
- Pack size:4
- Current:15 A
- Connectivity:Wi-Fi
- Energy monitoring:Yes
- Scheduling:Supported
- Voice control:Alexa and Google Assistant
- Auto-shutoff:Supported
- Remote control:App
Our verdict“Choose this four-pack when you want Tapo’s monitoring and control features on several appliances at once.”
Kasa Matter Smart Plug with Energy Monitoring, KP125M
The Kasa KP125M is the clearest fit for a home that mixes smart home platforms: Matter support covers Apple Home, Alexa, Google Home, and SmartThings, while local network control can keep nearby control working during an internet outage. Energy tracking makes it useful for checking which appliance is drawing power, rather than just switching it on and off. Compared with the Kasa KP115, this model offers broader platform compatibility, but the KP115 spells out safety features such as overheating protection and a sliding outlet cover. Its 15A / 1800W limit suits typical household devices, not higher-load equipment. Remote access still depends on internet service, so local control does not mean every function remains available offline.
Pros:- Matter support spans major smart home platforms
- Local network control can continue without internet
- Tracks energy use over time
- Compact body helps keep an adjacent outlet free
Cons:- Remote control requires internet access
- Maximum load is 15A / 1800W
- Listed safety details are less specific than the KP115’s
Best for: Households using a mix of Apple Home, Alexa, Google Home, or SmartThings that want energy tracking and local control.
Not ideal for: Buyers who need remote access during internet outages or want explicitly listed overheating protection and a sliding outlet cover.
- Model:KP125MP2

Our verdict“Choose the KP125M for Matter-based energy monitoring across mixed platforms, provided its 15A limit and internet-dependent remote access fit your setup.”
Kasa Smart Plug Mini with Energy Monitoring (KP115)
The Kasa KP115 makes sense for buyers who want energy monitoring in the familiar Kasa app and use Alexa or Google Assistant. Its standout distinction from the Kasa KP125M is its clearly specified overheating protection and sliding safety cover; the KP125M, by comparison, brings Matter support and local network control across more platforms. The KP115 is a more focused choice if your home already runs on 2.4 GHz Wi-Fi and those two assistants. That narrower compatibility is also its main tradeoff: it does not list Matter, Apple Home, or SmartThings support. The product data also gives no maximum load figure, so buyers matching a particular appliance to a capacity should check that limit before choosing it.
Pros:- Kasa app supports remote appliance control
- Works with Alexa and Google Assistant
- Includes overheating protection and a sliding safety cover
- UL certified with a 2-year warranty
Cons:- Requires a 2.4 GHz Wi-Fi connection

Our verdict“Pick the KP115 for Kasa app energy monitoring and its stated safety features if Alexa or Google control is all you need.”
Kasa Matter Smart Plug with Energy Monitoring, KP125MP4, 15A/1800W Max
This Kasa KP125MP4 brings the same useful Matter-and-energy-monitoring combination as the KP125M: it works with major platforms and supports local LAN control during internet outages. That makes it a stronger fit than the Kasa KP115 for households that span Apple Home, Alexa, Google Home, and SmartThings. Its 15A / 1800W ceiling gives buyers a clear capacity boundary for everyday appliances, and the compact, flame-retardant build is suited to crowded outlet areas. The tradeoff is that setup depends on compatible smart home apps and operation still relies on network stability. The supplied information does not identify a distinct capability over the other Kasa Matter model, so choose between them based on the specific listing and package details rather than assuming a performance difference.
Pros:- Matter support includes Apple Home, Alexa, Google Home, and SmartThings
- Energy monitoring helps track appliance consumption
- Local LAN control can work during internet outages
- Compact flame-retardant design
Cons:- Limited to 15A / 1800W

- Warranty:2 years
Our verdict“Choose the KP125MP4 for cross-platform Matter energy monitoring when its stated 15A / 1800W limit suits your appliance.”
Smart Plug with Energy Monitoring, 15A, 2.4 GHz Wi-Fi, 4-Pack
For buyers who want to monitor several devices at once, this four-pack is the practical choice in this group. Each plug tracks real-time power and energy use, while the SmartLife app adds schedules, timers, and group control. Compared with the Tapo P110M four-pack, this set is less focused on Matter integration but explicitly lists overload and short-circuit protection. Alexa and Google Assistant work through SmartLife, which adds a setup step before voice control is available. The plugs also require 2.4 GHz Wi-Fi and are limited to 15A / 1800W each. FCC certification is listed, but the product data does not state UL certification, so buyers who require that specific certification should check before choosing.
Pros:- Four plugs let buyers monitor multiple appliances
- Tracks real-time power and energy use
- SmartLife supports schedules, timers, and group control
- Lists overload and short-circuit protection
Cons:- Requires 2.4 GHz Wi-Fi
- Voice assistants must be linked through SmartLife

Our verdict“Choose this four-pack to add energy tracking and scheduling to several devices through SmartLife, if its Wi-Fi and app setup suit your home.”
Tapo Smart Plug, Matter Compatible, Energy Monitoring, P110M (4-Pack), 15A
The Tapo P110M four-pack combines Matter compatibility and energy monitoring across four plugs, making it a natural fit for buyers who want several appliances available in Apple Home, Alexa, Google Home, or SmartThings. Its platform breadth sets it apart from the SmartLife four-pack, which routes voice assistant support through its app and does not list Matter. Tapo also lists scheduling, remote control, and overcharge prevention, giving buyers more than on-off control. The stated 15A current limit still confines each plug to compatible loads, and the product description calls for a stable Wi-Fi connection. Unlike the Kasa Matter options, the supplied details do not mention local control during internet outages, so buyers prioritizing offline operation may prefer one of those Kasa models.
Pros:- Four Matter-compatible plugs cover multiple appliances
- Works with major smart home platforms
- Energy monitoring and scheduling support device management
- Overcharge prevention is listed
Cons:- Limited to 15A current
- Requires a stable Wi-Fi connection
- Local offline control is not specified
Best for: Matter households that want energy monitoring for several standard appliances across Apple Home, Alexa, Google Home, or SmartThings.
Not ideal for: Buyers who prioritize stated local control during internet outages or need a plug rated above 15A.
- Model:P110M
- Number of devices:4
- Compatibility:Matter, Alexa, Apple HomeKit, Google Home, Samsung SmartThings
- Energy monitoring:Yes
- Current:15A
- Overcharge prevention:Yes
- Voice control:Yes
- Remote control:Yes
Our verdict“Pick the Tapo P110M four-pack for Matter-based energy monitoring across several devices, if 15A capacity and Wi-Fi dependence fit your needs.”
How We Picked
I ranked these plugs around the job their energy monitoring can do for a buyer: track individual appliance use, support decisions about standby power, and fit into a smart home without adding avoidable setup friction. I also weighed connectivity, including Wi-Fi, Zigbee, and Matter, along with rated capacity, pack size, app and platform fit, and whether the listing makes the intended use clear. A feature only earns weight when it helps someone choose or use the plug.
Compatibility and practical fit drive the order. Kasa’s KP125M takes the top spot for pairing monitoring with Matter; Tapo’s P115 options rank well for buyers choosing between smaller and larger packs. Emporia is a strong multi-appliance choice, while the Zigbee THIRDREALITY plug fits buyers already set up for that protocol. The remaining picks may suit narrower needs, but buyers should compare their exact model, platform support, and pack contents before deciding. Every plug has a tradeoff: protocol limits, setup demands, or less clarity about how its monitoring fits a broader system.

Factors to Consider When Choosing Smart Plugs With Energy Monitoring
Before choosing a plug, I’d match the monitoring feature to a real decision you want to make. That might mean spotting a device that draws power while idle, comparing appliance use over time, or checking whether a schedule changes consumption. These broader factors can help you avoid buying a multipack or smart home protocol that does not fit your home.
Decide What You Want the Energy Data to Tell You
Energy monitoring can mean a live watt reading, a running consumption total, or historical records in an app. Those views answer different questions: a live reading helps check whether a device is drawing power, while longer records help compare usage across days or weeks. Before buying, check what the app displays and whether it retains history in a way you can use. Avoid assuming that every plug calculates appliance running costs automatically; cost estimates depend on your electricity rate and the app’s settings. If you mainly want to find standby drain, a clear watt reading may matter more than elaborate charts. For household energy planning, look for data exports or reporting features if you need to compare readings outside the plug’s app.
Match the Protocol to Your Smart Home
Wi-Fi plugs typically connect directly to a home network, while Zigbee plugs need a compatible hub or coordinator. Matter can make cross-platform setup easier, but support still depends on the controller and the features exposed by each manufacturer. A Matter label does not guarantee that every energy reading appears in every ecosystem. Check the exact plug model and your intended platform before ordering, especially if you rely on voice control or automations. Also confirm whether setup requires a manufacturer account or app. A plug that fits your existing setup may be more useful than one with broader compatibility on paper.
Check Appliance Load and Outlet Fit
Rated current and wattage set the boundary for what a plug should control. Compare the plug’s stated rating with the appliance label, and follow the manufacturer’s restrictions for motors, heaters, and other high-draw devices. A 15A rating does not mean every appliance is suitable, and a smart plug should not be used to bypass electrical safety guidance. Physical size matters too: a bulky plug may block a neighboring outlet or sit poorly behind furniture. For large or critical loads, check whether a smart plug is an appropriate control device at all. These checks matter more than adding extra app features.
Choose Pack Size Around Your Monitoring Plan
A multipack can make it easier to compare several appliances, but only if you have a clear plan for where each plug will go. Start with devices whose use you can act on, such as entertainment equipment or a desk setup, rather than spreading plugs across appliances with no follow-up decision. A smaller pack can help you learn whether the app’s readings are useful before expanding. When comparing bundles, verify that every plug is the same model and supports the same protocol. Pack size does not tell you whether the plugs can be grouped or managed together in software. Think about outlet availability and Wi-Fi or hub coverage in the rooms you want to monitor.
Separate Monitoring From Measurement Accuracy Claims
Energy readings are useful for trends and comparisons, but their precision can vary with the plug, appliance, and measurement conditions. Treat small differences between devices as directional unless the manufacturer provides accuracy specifications that suit your purpose. If you need data for billing, compliance, or precise electrical diagnosis, a consumer smart plug may not be the right instrument. For ordinary home decisions, consistent readings over time are often more actionable than a single number. Check whether the app reports watts, energy over time, and voltage or current, since those values serve different purposes. Keep the plug and app updated, and avoid making safety decisions from monitoring data alone.
Frequently Asked Questions
Will a Matter smart plug show energy use in every smart home app?
Not necessarily. Matter can simplify device connection across supported platforms, but the energy data shown can depend on the plug, controller, and app version. Check the model’s compatibility details for the specific ecosystem you use, including whether energy monitoring is exposed there. The manufacturer’s own app may offer readings that a third-party app does not. If energy history is your main reason for buying, verify that feature before choosing based on Matter support alone.
Should I buy a two-pack or four-pack if I have not used energy monitoring before?
A smaller pack is a practical starting point if you are unsure whether the readings will change your habits or automations. Try monitoring one or two devices whose use you can adjust, then decide whether the app gives you useful information. A four-pack makes more sense when you already have several target appliances and enough outlets in range. Check whether the bundle uses the same model throughout, since protocol and app features can differ between product lines. The Tapo P115’s two- and four-pack listings make that choice especially direct in this roundup.
Can I use an energy-monitoring smart plug with a heater or refrigerator?
Do not assume that a stated 15A rating makes a plug suitable for every high-draw appliance. Check the plug maker’s instructions and the appliance’s electrical requirements, paying particular attention to motors, compressors, and heating elements. Some manufacturers restrict specific load types even when the printed rating appears adequate. A refrigerator also needs reliable power, so avoid automations that could switch it off unexpectedly. When the instructions are unclear, use an outlet or control device rated for the appliance rather than relying on monitoring features.
Do I need a hub for these smart plugs?
It depends on the connection method of the exact model. Wi-Fi options generally connect through your router, while Zigbee devices such as the THIRDREALITY Gen3 require a compatible hub or coordinator. Matter plugs still need a suitable Matter controller for the platform you plan to use, even if they do not need a separate Zigbee hub. Before buying, check both the plug’s protocol and the devices already in your home. An existing compatible hub can make a Zigbee option a sensible fit; without one, a Wi-Fi model may involve fewer setup steps.
Are energy-monitoring readings enough to calculate my appliance’s electricity cost?
They can help estimate cost, but you need the energy total and your electricity rate. Some apps let you enter a rate or display a cost estimate, while others focus on consumption readings. Rates can vary by time, plan, and region, so a fixed estimate may not match your bill. Use readings to compare an appliance’s use over time or identify likely standby drain, then check your utility details for a better cost calculation. If exact accounting matters, confirm how the plug measures and stores data before relying on the estimate.
Conclusion
For most buyers, I recommend the Kasa Matter KP125M as the best overall balance of monitoring and cross-platform flexibility. The Tapo P115 is my best value fit for buyers who want a choice of pack size, while Emporia’s four-pack suits people planning to monitor several appliances together. For beginners, I’d start with the smaller Tapo P115 pack and confirm that its app presents the readings you want. Choose THIRDREALITY Gen3 for a Zigbee setup that already has a compatible hub, and consider the Kasa Matter KP125MP4 when you want a larger Matter-enabled set. Match the exact model to your platform and appliance load before choosing.
