More Details on Our Top Picks
Tapo P115 Smart Wi-Fi Plug with Energy Monitoring, 15A, 2-Pack
The Tapo P115 two-pack suits buyers who want energy-use charts and everyday control without building around a particular smart-home standard. Its Tapo app, schedules, and Alexa and Google Assistant support make it easy to monitor and automate two appliances, while automatic overload shutoff adds a safety measure. Compared with the Matter-enabled Kasa KP125MP2, this Tapo uses conventional 2.4 GHz Wi-Fi and does not offer the same cross-platform Matter flexibility. In return, its smart-charging feature can stop power at a chosen battery limit, a useful extra for charging devices. The 1,800 W ceiling is typical for this lineup, not a route to controlling higher-load equipment, and operation depends on a 2.4 GHz network.
Pros:- Energy statistics and charts help track connected-device consumption.
- Smart charging can stop power at a selected battery limit.
- Alexa, Google Assistant, app, and remote control options.
- Compact plug design helps keep adjacent outlets usable.
Cons:- Requires a 2.4 GHz Wi-Fi connection.
- The 1,800 W maximum limits use with higher-load equipment.
Best for: Households wanting two plugs for app-based energy tracking, schedules, and Alexa or Google Assistant control, especially for charging devices.
Not ideal for: Matter-first smart-home owners or buyers with only 5 GHz Wi-Fi, since this plug relies on 2.4 GHz Wi-Fi and lacks the listed Matter support.

Our verdict“Choose the Tapo P115 if you want two compact, app-managed energy monitors with useful charging controls rather than Matter-based platform flexibility.”
Kasa Matter Smart Plug with Energy Monitoring, 15A/1800W, 2-Pack
For buyers who want energy monitoring across a mixed smart-home setup, the Kasa KP125MP2 makes Matter its key advantage. It supports Apple Home, Alexa, Google Home, and SmartThings, so two plugs can fit into more than one ecosystem without making the Kasa app the only control route. Local Matter communication can also keep compatible devices talking when internet access drops. Compared with the Wi-Fi-only Tapo P115, Kasa offers broader platform flexibility, but it does not list Tapo’s smart-charging cutoff feature or overload shutoff. Its energy monitoring helps reveal appliance consumption; the 15 A, 1,800 W rating sets a firm ceiling rather than accommodating higher-demand equipment. A 2.4 GHz Wi-Fi network is still required for setup and connectivity.
Pros:- Matter support spans Apple Home, Alexa, Google Home, and SmartThings.
- Local Matter control can function without an internet connection.
- Energy monitoring adds consumption visibility for connected appliances.
- Compact, UL-certified flame-retardant design.
Cons:- Requires 2.4 GHz Wi-Fi.
- Rated up to 15 A and 1,800 W, so it is not for higher-load equipment.
- No overload shutoff or smart-charging feature is listed.
Best for: Smart-home households using Apple Home, Alexa, Google Home, or SmartThings that want two Matter-compatible plugs with energy monitoring.
Not ideal for: Buyers who need a plug with a listed overload-shutoff feature, smart-charging cutoff, or support for Wi-Fi bands other than 2.4 GHz.

Our verdict“Pick the Kasa KP125MP2 if Matter compatibility across two outlets matters more than specialized charging or overload controls.”
Tapo P110M Matter-Certified Smart Plugs with Energy Monitoring, 4-Pack, 15A
The Tapo P110M four-pack is the strongest fit here for monitoring several appliances while keeping Matter compatibility in the mix. It combines energy statistics and bill estimates with scheduling and configurable power thresholds, giving users more ways to act on consumption data than a basic on/off routine. Its support for Apple HomeKit, Alexa, Google Home, and SmartThings also makes it more adaptable across platforms than the non-Matter Tapo P115. The tradeoff is that some energy-management functions depend on compatible billing-system integration, so not every buyer will get the same usefulness from the estimates. Like the Kasa four-pack, it is limited to 2.4 GHz Wi-Fi and 1,800 W; choose this Tapo when thresholds and its listed energy features matter more than Kasa’s listed two-year warranty.
Pros:- Four plugs support energy tracking across several appliances.
- Matter works with several major smart-home platforms.
- Configurable power thresholds and scheduling support automated power management.
- Energy statistics and bill estimates provide more context than basic on/off control.
Cons:- Some energy-management functions require compatible billing-system integration.

SIXWGH Matter Smart Plug with Energy Monitoring, Timer, and Voice Control
The SIXWGH Matter plug stands out for buyers who want energy monitoring alongside a wider set of timer behaviors than the simpler schedules listed for the Kasa KP125MP2. Through the Smart Life app, it tracks energy use and supports schedules, countdowns, cycle timers, and random timers; group control adds a way to manage multiple compatible devices together. Matter support covers Alexa, Apple Home, Google Home, SmartThings, and Siri, while Bluetooth-assisted pairing helps with setup. The main limitation is scale: this is a single plug, unlike the four-unit Tapo P110M, so outfitting several appliances means buying additional units. It also relies on 2.4 GHz Wi-Fi, and its IP00 rating offers no stated ingress protection, making it a poor fit for damp or exposed locations.
Pros:- Energy monitoring is available through the Smart Life app.
- Schedules, countdowns, cycle timers, and random timers offer varied automation.
- Matter support covers several major ecosystems, including Siri-compatible Apple Home.
- Compact form and overload protection suit standard household outlets.
Cons:- Sold as a single plug, unlike the Tapo P110M four-pack.

Our verdict“Pick the SIXWGH if timer flexibility for one device matters more than buying several energy-monitoring plugs together.”
Kasa Matter Smart Plug with Energy Monitoring, KP125M (4-Pack)
The Kasa KP125M four-pack is a practical choice when the goal is to add energy monitoring to several outlets without sacrificing Matter compatibility. It supports Apple Home, Alexa, Google Home, and SmartThings, and its local Matter control can let compatible devices communicate when internet access is unavailable. Compared with the Kasa KP125MP2, this pack is better suited to covering more appliances at once; compared with the Tapo P110M, its listed strengths are the UL-certified flame-retardant design and a two-year limited warranty rather than power thresholds or bill estimates. The monitoring can help identify which connected devices draw power, but the supplied data does not specify advanced energy-management features. Its 15 A, 1,800 W limit and 2.4 GHz Wi-Fi requirement remain the same constraints as the two-pack.
Pros:- Four plugs cover more appliances than the Kasa two-pack.
- Matter compatibility spans Apple Home, Alexa, Google Home, and SmartThings.
- Local Matter communication can continue between compatible devices without internet access.
- Compact, UL-certified flame-retardant design with a 2-year limited warranty.

Emporia Energy Monitoring Smart Plug with Wi-Fi, App Control, Scheduling, and Alexa and Google Home Compatibility, 4-Pack
The Emporia 4-pack makes the most sense for buyers who want to monitor several everyday appliances and already use, or plan to use, the Emporia app. It tracks connected-device energy use and adds schedules, remote control, and Alexa or Google Assistant support, giving it a useful monitoring-and-control mix. Compared with the AiSeek 4-pack, its clearest distinction is its Emporia app ecosystem rather than SmartLife; the AiSeek also lists a 15A rating, while Emporia is limited to 10A continuous, with 15A allowed only as a short peak. That load limit narrows which appliances are suitable. A 2.4 GHz Wi-Fi network is required, and the on-off operation does not provide fine-grained device control. I’d choose it for lamps, fans, and other modest loads, not high-draw appliances.
Pros:- Monitors energy use for connected devices.
- Four plugs support monitoring multiple appliances.
- App offers remote control and scheduling.
- Works with Alexa and Google Assistant.
Cons:- 10A continuous-load limit excludes some higher-draw appliances.

Not ideal for: Buyers monitoring appliances that draw more than 10A continuously, or homes with only 5 GHz Wi-Fi.
- Model:EMSO1-4
- Pack size:4 plugs
- Operating voltage:120 V
- Continuous load:10 A
- Peak load:15 A for up to 1 hour per day
- Connectivity:2.4 GHz Wi-Fi
- Energy monitoring:Yes
- Compatible assistants:Amazon Alexa, Google Assistant
- Dimensions:1.97 x 3.31 x 1.5 inches
Our verdict“Choose the Emporia set if its app fits your setup and your monitored appliances stay within its 10A continuous-load limit.”
Eve Energy Outlet Matter Smart Outlet with Power Meter
The Eve Energy Outlet takes a different approach from the single-outlet plugs in this roundup: it controls two outlets independently and supports Matter over Thread. That layout can consolidate control at one wall receptacle, while its power meter adds energy visibility for connected devices. Its standout advantage over the SONOFF S61s is local communication without Eve cloud services, registration, or tracking. That privacy-conscious setup comes with a real entry requirement: a compatible platform hub and Thread router are needed, so this is not the simplest plug-in option. Eve supports several major platforms, but the setup also has stated iOS/iPadOS or Android software requirements. I’d shortlist it for a built-out smart home where local control and two separately managed outlets matter more than a quick, hub-free installation.
Pros:- Two outlets can be controlled independently.
- Power meter provides energy-use monitoring.
- Matter and Thread support several major smart-home platforms.
- Local communication does not rely on Eve cloud services, registration, or tracking.
Cons:- Requires both a compatible platform hub and a Thread router.

Our verdict“Pick Eve if you already have a compatible Thread setup and value local control of two independently monitored outlets.”
AiSeek Smart Plug with Energy Monitoring, 15A, 2.4 GHz Wi-Fi, 4-Pack
The AiSeek four-pack is aimed at buyers who want energy monitoring across several devices without adding a hub. Its SmartLife app combines real-time monitoring, timers, schedules, and group control, and the plugs are rated up to 15A and 1800W. That makes the listed load capacity higher than the Emporia set’s 10A continuous limit, although both still require 2.4 GHz Wi-Fi. Against the Tapo P115 4-pack, AiSeek offers much the same broad household use case, but its app route is a key practical difference: SmartLife setup comes before linking Alexa or Google Assistant, and direct Alexa connection is not supported. Buyers comfortable with that app dependency get a four-plug, hub-free way to track usage and automate devices; those seeking a simpler app path may prefer Tapo.
Pros:- Four plugs each support energy monitoring up to 15A and 1800W.
- SmartLife provides schedules, timers, remote control, and group control.
- Works with Alexa and Google Assistant after SmartLife setup.
- No hub is required, and the housing is described as fire-resistant.

- Warranty:2 years
Our verdict“Choose AiSeek for a four-device, hub-free monitoring setup if you are comfortable managing it through SmartLife.”
Tapo P115 Smart Wi-Fi Plug with Energy Monitoring, 4-Pack, 15A
The Tapo P115 four-pack suits buyers who want energy monitoring they can review over time, not just a live reading: its app provides usage statistics and charts. It also combines scheduling with smart charging and automatic shutoff, so a plug can stop charging at a chosen battery level or cut power when a device exceeds the plug’s capacity. Compared with the AiSeek 4-pack, the P115’s strongest distinction is that more specific app-based charging and shutoff toolkit; both offer four plugs, 2.4 GHz Wi-Fi, and a 15A/1800W rating. The tradeoff is that Tapo is also tied to 2.4 GHz Wi-Fi, and its maximum output limits which appliances are appropriate. Its compact design is useful where a larger plug might block a neighboring outlet, though the supplied details do not state its dimensions.
Pros:- Usage statistics and charts make energy history easier to review.
- Smart charging can stop at a chosen battery level.
- Automatic shutoff can respond to devices exceeding the plug’s capacity.
- Four-plug set supports Alexa, Google Assistant, and SmartThings.

- Maximum power:1800 W
- Maximum current:15 A
- Connectivity:2.4 GHz Wi-Fi
- Energy features:Monitoring, usage statistics, charts
- Control platforms:Tapo app, Alexa, Google Assistant, SmartThings
- Certifications:ETL, FCC, RoHS
Our verdict“Pick the Tapo P115 if historical energy charts and charging or capacity-based shutoff are more useful to you than a basic monitoring plug.”
SONOFF S61s Matter Smart Plug with Energy Monitoring, 15A
The SONOFF S61s is a strong fit for buyers who want one monitored outlet to work across several smart-home platforms. Its Matter-over-Wi-Fi support covers Apple Home, Alexa, Google Home, and SmartThings, with no hub required; energy tracking includes both real-time use and electricity costs. Compared with the Eve Energy Outlet, SONOFF trades Eve’s two independently controlled outlets and Thread-based local setup for a single plug with a stated hub-free connection path. It also offers 15A capacity, overload protection, scheduling, and automation. The main limitation is network compatibility: it requires 2.4 GHz Wi-Fi. Its IP20 rating provides limited protection from dust and moisture, so I’d keep it in dry indoor locations rather than treat it as an outdoor or damp-area option.
Pros:- Tracks real-time power use and electricity costs.
- Matter support spans Apple Home, Alexa, Google Home, and SmartThings.
- No hub is required for its stated Matter-over-Wi-Fi setup.
- Includes overload protection and fire-resistant housing.

- Protection:Overload protection; IP20 ingress protection
- Warranty:2 years
Our verdict“Choose the SONOFF S61s for single-outlet energy and cost tracking with broad Matter platform support in a dry indoor space.”
Govee Smart Plug with Energy Monitoring, Wi-Fi and Bluetooth, 4-Pack
The Govee four-pack suits households that want to compare an appliance’s consumption over time: its app tracks power, current, and voltage, with history available for up to a year. That longer record gives it an advantage for spotting seasonal changes or checking whether a schedule affects usage. Like the Emporia Energy Monitoring Smart Plug, it offers app-based monitoring across several plugs, but Govee also supports Bluetooth alongside Wi-Fi and allows group control. It works with Alexa and Google Assistant without a hub, which is simpler to set up than the Minoston Z-Wave plug. The tradeoff is reliance on Govee Home for monitoring and app control, plus the need for a 2.4 GHz Wi-Fi network; 5 GHz is unsupported. Choose it for accessible, detailed tracking, not for hub-free operation on any Wi-Fi band.
Pros:- Tracks power, current, and voltage, with data history for up to one year
- Group control, remote operation, and scheduling through the app
- Works with Alexa and Google Assistant without a hub
- Four plugs in the pack make it practical to monitor several appliances

Our verdict“Choose Govee if long-term, multi-measurement tracking across several appliances matters more to you than app flexibility or 5 GHz Wi-Fi support.”
Minoston Z-Wave Smart Plug with Energy Monitoring, 800 Series, Repeater, and Alexa and Google Assistant Compatibility (MP21ZP)
The Minoston MP21ZP is the pick for a smart home already built around Z-Wave: it reports energy use through a compatible hub and can also act as a network repeater. With a Long Range-compatible hub, the stated range reaches up to 1,300 feet, which may help connect devices farther from the hub. Its 800 Series chip, S2 security, and SmartStart pairing make it more specialized than the Wi-Fi-based Govee Smart Plug, which connects directly to a home network and tracks power, current, and voltage in its app. Minoston’s product details confirm energy monitoring but don’t specify the same measurement breakdown or history length. The main cost of choosing this plug is setup dependence: control and voice-assistant support require a compatible Z-Wave hub, and Long Range performance depends on that hub too.
Pros:- Acts as a Z-Wave repeater as well as an energy-monitoring plug
- 800 Series chip with S2 authenticated security
- SmartStart pairing is supported
- Compatible with several hubs, including SmartThings, Hubitat, Vera, and Z-Box Hub

How We Picked
I compared these plugs on the factors that shape everyday usefulness: energy-monitoring support, setup and app control, smart-home compatibility, outlet format, and the number of plugs included. A reading is most helpful when it is easy to find and connect to the routines or appliances a buyer wants to track, so I gave weight to the overall monitoring and control experience rather than treating the presence of a meter as enough. I also considered protocol requirements: a plug that depends on a compatible hub serves a narrower audience than a Wi-Fi model, while Matter can help buyers who use supported platforms from different brands.
The order favors broad usefulness first, then more specialized strengths. Tapo P115 leads as an accessible everyday pick; Kasa’s Matter multipacks rise for buyers building out multiple outlets with broader platform flexibility. Emporia and Eve serve buyers with more specific monitoring or ecosystem priorities, while Z-Wave, Bluetooth-assisted, and lesser-known Wi-Fi options rank lower for most households because their appeal depends more on existing equipment, preferred platforms, or comfort with a narrower product ecosystem. Pack size is part of the comparison, but it does not outweigh compatibility or usability.
Factors to Consider When Choosing Smart Plugs With Energy Monitoring
Before choosing a plug, I’d start with what you want to learn from its energy data and how it needs to fit into your home. These decisions can matter more than the product name or the number of outlets in a bundle.
Choose a protocol your home can support
Check your existing smart-home setup before buying, including whether it relies on Wi-Fi, Matter, or Z-Wave. Matter support can help compatible devices work across supported platforms, but it does not remove the need to check each platform’s features and setup requirements. Z-Wave plugs typically make the most sense when you already have a compatible hub or controller. Wi-Fi models may be simpler to add, though they still depend on your network and the manufacturer’s app. A common mistake is buying around a protocol label without checking whether your hub, router, and voice assistant support the functions you want. Match the plug to the system you already use, unless you have a clear reason to expand it.
Decide what you need the energy data to tell you
Energy monitoring can mean a quick look at an appliance’s consumption or a longer-term record that helps you compare usage over time. Think about whether you want live readings, historical tracking, alerts, or a way to connect consumption with schedules. Those features depend on the app and platform as well as the plug’s meter. If you are tracking a fridge or another appliance that runs continuously, access to trends may matter more than a simple on-and-off control. Avoid assuming that every plug presents data in the same way or supports the same reports. Check the software details for the monitoring task you have in mind before choosing a multipack.
Check the appliance and outlet before plugging in
Confirm that the appliance’s electrical requirements fall within the plug’s stated rating and the limits of your household outlet. A smart plug is not a general-purpose replacement for every kind of electrical control, and high-power or motor-driven appliances deserve careful compatibility checks. The shape and size of the plug can also block a neighboring socket, especially on crowded outlet strips. Consider whether the device will sit behind furniture, where its status light or reset button may be hard to reach. Buyers sometimes focus on amperage and overlook the physical fit. Measure the available space and check the appliance manual when the load is unusual.
Buy the right number of monitored outlets
A two-pack is often a sensible way to start if you have a couple of appliances to track, while a four-pack can make sense for a home office or several rooms. Larger bundles lower the chance of mixing apps and protocols across outlets, but only if you will actually use all the plugs. Before buying, list the appliances you want to monitor and note where each outlet is located. That exercise can reveal that you need different plug types or that a single premium outlet is enough. Don’t count on unused plugs as savings if they complicate setup or sit in a drawer. Match bundle size to real locations and monitoring plans.
Weigh app dependence against ecosystem flexibility
Many smart plugs rely on a companion app for setup, schedules, and access to energy readings. If you want to manage devices in one place, check how the plug works with your chosen smart-home platform and whether monitoring data appears there or only in the brand’s app. Matter can broaden control options for compatible devices, though specific energy features may still vary by platform. A plug that works with a voice assistant may let you switch it on and off without exposing its energy history in that assistant’s interface. Check which controls you need day to day, and which you need only during setup. This helps prevent a purchase that connects successfully but leaves key monitoring features inconvenient to reach.
Know when a hub or more detailed monitoring matters
A hub adds equipment and setup steps, but it can be the right choice if you already rely on its protocol or want devices coordinated through that system. Buyers without a compatible hub should count its role in the total setup before choosing a hub-dependent plug. For energy tracking, consider whether a plug-level view is enough or whether you need household-level analysis from a broader monitoring system. Smart plugs can help isolate the consumption of individual devices, but their readings do not replace a whole-home view. Choose the simpler setup when you only need to compare a few appliances. Pay for extra infrastructure when it supports a system you already use or a monitoring goal that a basic app cannot meet.
Frequently Asked Questions
Will these plugs show energy use in Apple Home, Google Home, or Alexa?
That depends on both the plug and the platform; voice control compatibility does not automatically mean energy readings appear in the same app. Matter may improve cross-platform device control for supported combinations, but energy-monitoring features can still be exposed differently. Check the manufacturer’s current compatibility details for the specific assistant and the readings you want to see. If energy history is your priority, confirm whether it lives in the plug maker’s app or the platform you use every day. This avoids choosing a plug that controls well but keeps its useful data elsewhere.
Can I use a smart plug to find out which appliance is costing me the most to run?
You can compare the energy use reported for individual plugged-in appliances, which can help identify devices that draw more power over a chosen period. The usefulness of that comparison depends on the app’s history and reporting, so check how it stores and presents readings. A single plug only tracks the device connected to it; it does not measure the rest of the home. For an appliance that cycles on and off, observe it over a representative period rather than relying on a brief snapshot. Treat the data as a guide to relative use and review the app’s measurement details before making precise cost estimates.
Is Matter worth choosing if my current smart home already works?
Matter is most useful when you want a compatible plug to fit into supported smart-home platforms without relying as heavily on one brand’s ecosystem. If your current setup is stable and you only need basic control and monitoring in one app, a non-Matter option may meet your needs. Matter support also does not guarantee that every energy report or automation is available in every platform. Check whether your controller and app support the plug’s features before treating Matter as a reason to upgrade. It is a useful compatibility factor, not a substitute for checking the exact functions you plan to use.
Should I buy a four-pack if I only want to monitor two appliances?
Not necessarily. A smaller bundle can be a better fit when you have only a couple of known monitoring targets, especially if the remaining plugs would go unused. A larger pack can make sense if you expect to add outlets soon and want consistent setup across them. Consider the protocol and app alongside the quantity, since a bundle of plugs that do not fit your ecosystem is poor value for your home. List likely locations first and check that each one has a suitable outlet and appliance. Choose extra plugs for a real expansion plan, not only because the pack contains more.
Do I need a Z-Wave hub for the Minoston MP21ZP?
The Minoston is a Z-Wave model, so you need a compatible Z-Wave controller or hub to integrate it into a smart home. It is a natural candidate when that infrastructure is already in place, and its repeater function may fit a Z-Wave network that benefits from another powered node. If your home uses Wi-Fi or Matter without a Z-Wave controller, factor the extra hub into your setup decision. Also confirm that your controller supports the plug’s energy reporting and the automations you want. For a new, simple setup, a Wi-Fi or Matter plug from this roundup may be a more direct route.
Conclusion
For the best overall balance, I’d choose the Tapo P115 2-Pack; its four-pack is the better fit when you already know you need more monitored outlets. The best value for a multi-outlet setup is the Kasa Matter KP125M 4-Pack, especially for a compatible smart home that benefits from Matter. For a premium single outlet, Eve Energy suits buyers who want its Matter-focused approach and are comfortable with its ecosystem fit. The best beginner pick is Tapo P115 for a straightforward start with a couple of appliances. For specific needs, choose Emporia for app-based monitoring across several outlets, or Minoston when your home already runs Z-Wave; the protocol should decide that choice.
