For most homes, I’d start with the Kasa KP115: it pairs energy monitoring with a familiar Wi-Fi setup and a compact single-plug format. The Tapo P115 four-pack is a strong pick when you want to monitor several appliances, while the THIRDREALITY Gen3 suits homes already using Zigbee. The main tradeoffs are whether you want Wi-Fi, Matter, or Zigbee, and whether you need detailed tracking, broad smart home compatibility, or several plugs in one purchase. Pack size and the quality of the monitoring app can matter as much as the outlet itself. Read on for how all 12 options compare and which one fits your setup.

More Details on Our Top Picks
SwitchBot Smart Plug Mini – 15A Energy Monitoring, WiFi & Bluetooth Outlet
The SwitchBot Smart Plug Mini is my strongest all-around pick for buyers who want useful energy data without giving up broad smart-home compatibility. Its per-second power updates and data export make it easier to spot changing consumption than the Kasa KP115, whose supplied details confirm monitoring but do not specify that level of data access. WiFi and Bluetooth add a fallback for nearby control if WiFi drops, and its 1-inch square body is less likely to cover the neighboring socket than the larger NOUS A9. The tradeoff is that Bluetooth cannot replace WiFi for control from farther away, and Siri or SmartThings may take extra setup. Choose it for flexible ecosystem support and detailed monitoring; skip it if you need the simplest setup or reliable remote control during an internet outage.
Pros:- Per-second energy updates and data export provide detailed usage visibility
- WiFi and Bluetooth connectivity offer a nearby fallback control path
- 1-inch by 1-inch design is less likely to block the adjacent outlet

Our verdict“Choose the SwitchBot for broad ecosystem support and detailed energy data in a compact plug, provided its setup and Bluetooth limits suit your home.”
Kasa Smart Plug Mini with Energy Monitoring (KP115)
The Kasa KP115 suits buyers who want app and voice control with energy monitoring, plus clearly specified safety features. Its overheating protection, fire-resistant shell, and sliding child safety cover make it a more safety-focused choice than the Govee four-pack, whose supplied details mention fire-resistant materials but not a child safety cover. Kasa app control and Alexa or Google Assistant support keep everyday operation familiar, while the two-year warranty adds a defined support period. The tradeoff is a narrower ecosystem: the listed voice assistants are Alexa and Google, compared with the SwitchBot’s broader platform support. It also requires 2.4 GHz WiFi. Pick the KP115 for a single plug with specified safeguards; skip it if Matter or broader smart-home compatibility matters more.
Pros:- Energy monitoring is included for tracking connected appliance use
- Overheating protection, fire-resistant shell, and sliding child safety cover
- Kasa app supports remote control alongside voice commands

Kasa Matter Smart Plug with Energy Monitoring (KP125MP4)
The Kasa KP125MP4 is the lineup’s clearest fit for buyers building around Matter. It combines energy monitoring with Apple Home, Alexa, Google Home, and SmartThings compatibility, while local LAN control lets devices keep working if the internet goes offline. That local operation gives it an advantage over the WiFi-dependent KP115 when internet access is interrupted, and its 15A/1800W rating is stated outright. The tradeoff is that full functionality requires a Matter-compatible hub or controller, so it is less appealing as a standalone purchase than the SwitchBot, which lists no hub requirement. Its compact form helps preserve the second outlet, too. Choose this model when cross-platform Matter support and local control matter; skip it if you do not already have, or plan to add, a compatible controller.
Pros:- Matter support spans Apple Home, Alexa, Google Home, and SmartThings
- Local LAN control can keep devices operating without internet access
- Energy monitoring is built in
- Compact design avoids blocking adjacent outlets
Cons:- Full functionality requires a Matter-compatible hub or controller

NOUS A9 5GHz Wi-Fi Smart Plug 15A with Energy Monitoring
The NOUS A9 stands apart by supporting both 2.4 GHz and 5 GHz WiFi, a useful fit for buyers whose network setup makes dual-band device support a priority. It also provides real-time energy monitoring through the Tuya Smart app, plus schedules and timers without a hub. Compared with the Kasa KP115, the A9 offers 5 GHz connectivity, while the Kasa’s listed connection is limited to 2.4 GHz; the Kasa, in turn, specifies UL certification and several safety features that are not listed for the A9. Its stated dimensions are compact enough to leave the second outlet clear, though it is not as small on paper as the SwitchBot. The tradeoff is indoor-only IP20 use and a narrower listed assistant set of Alexa and Google Assistant.
Pros:- Supports both 2.4 GHz and 5 GHz WiFi
- Real-time energy monitoring through the Tuya Smart app
- Scheduling, timers, and voice control are supported
- Compact design is described as leaving the second outlet clear

Govee Smart Plug with Energy Monitoring, WiFi Bluetooth Outlet, 4 Pack
The Govee four-pack is the practical choice for buyers who want energy monitoring in several rooms at once. The Govee Home app tracks power, current, and voltage, with daily, weekly, and monthly data available for up to a year; that makes its monitoring detail more explicit than the supplied KP115 description. Group control, timers, and scheduling also help manage several appliances together. Each plug combines 2.4 GHz WiFi with Bluetooth and supports Alexa and Google Assistant. Compared with the SwitchBot, though, Govee’s Bluetooth is paired with WiFi but the supplied details do not describe it as a WiFi-failure fallback; the SwitchBot explicitly does. Govee also requires its app for setup and full features, and does not support 5 GHz WiFi. Choose it for multi-room tracking; skip it if you need a single plug or broader platform support.
Pros:- Four plugs make it possible to monitor appliances in multiple rooms
- Tracks power, current, and voltage with daily, weekly, and monthly data up to one year
- Supports group control, scheduling, and timers
- ETL and FCC certifications and fire-resistant materials are specified
Cons:- WiFi is limited to 2.4 GHz

TOPELER 15A Smart Plug with Energy Monitor, Timer & Remote Control, 2 Pack
The TOPELER 15A stands out for pairing Wi-Fi control with Bluetooth backup, so a local connection can still be available when Wi-Fi drops. Its energy reports cover daily, weekly, and monthly use, which helps track whether a schedule is cutting consumption over time. Compared with the Tapo P115 2-Pack, TOPELER offers Bluetooth fallback, while Tapo adds smart charging and overload shutoff features. The two plugs support loads up to 15A and fit without blocking adjacent outlets, making them easier to place around a crowded wall plate. The tradeoffs are 2.4GHz-only Wi-Fi and an initial Smart Life app link before Alexa or Google Assistant control works. Buyers seeking more protective charging features may prefer Tapo; this pair suits those who value backup control.
Pros:- Daily, weekly, and monthly energy reports help reveal usage patterns
- Bluetooth offers local control when Wi-Fi is offline
- 15A rating supports compatible higher-load devices
- Compact body avoids blocking adjacent outlets
Cons:- Wi-Fi connection is limited to 2.4GHz

Our verdict“Choose TOPELER if Bluetooth fallback and longer-term energy reports matter more to you than the Tapo P115’s smart charging and overload shutoff features.”
Tapo P115 Smart Plug Wi-Fi with Energy Monitoring (2-Pack), 15A
The Tapo P115 2-Pack pairs energy charts and usage statistics with features aimed at protecting connected devices. Its smart charging cutoff can stop power at a set battery limit, while automatic shutoff is intended to respond to electrical overload. Those protections make it a more focused choice for charging setups than the TOPELER 15A 2-Pack, which instead offers Bluetooth fallback when Wi-Fi is down. Tapo also supports schedules, remote app control, and Alexa or Google Assistant commands, so buyers can manage compatible loads away from home. The limits are a 15A maximum and reliance on both the Tapo app and Wi-Fi for smart features. Pick this pair for detailed tracking and charging controls; skip it if offline local control is a priority.
Pros:- Usage statistics and charts make energy patterns easier to review
- Smart charging cutoff can stop power at a chosen battery limit
- Automatic overload shutoff adds a layer of protection
- Remote app and voice control work with Alexa and Google Assistant
Cons:- Smart features require the Tapo app and a Wi-Fi connection

Tapo P115 Smart Plug Wi-Fi with Energy Monitoring (4-Pack), 15A
For buyers who want to track several appliances around the home, the Tapo P115 4-Pack provides the same energy charts and scheduling features as the two-plug version, with four outlets to distribute across rooms. Its smart charging cutoff and overload shutoff can help manage charging and compatible higher-power devices, while Alexa and Google Assistant add voice control. Compared with the Emporia 4-Pack, Tapo supports up to 15A rather than Emporia’s 10A continuous load, giving it broader capacity for compatible appliances. Tapo still depends on its app and Wi-Fi for smart features, and the supplied description says bill estimates may require billing-system setup. Choose this bundle when you need wider coverage; a smaller household may find the two-plug Tapo set a better fit.
Pros:- Four plugs extend monitoring and scheduling across multiple rooms
- Charts and statistics help compare device energy use
- 15A capacity exceeds the Emporia 4-Pack’s 10A continuous rating

Our verdict“Choose this Tapo bundle to monitor several rooms with 15A plugs, and choose the two-pack if four monitored outlets would go unused.”
Emporia Energy Monitoring Smart Plug (4 Pack)
The Emporia 4-Pack is a practical fit for spreading energy monitoring across several rooms, with real-time tracking, schedules, remote app control, and voice commands through Alexa or Google Assistant. Its defining tradeoff is capacity: each plug supports 10A continuous (1200W), below the 15A rating on both Tapo P115 bundles. That makes Emporia a better match for lamps, entertainment gear, and other compatible lower-draw devices than for loads that need the full 15A allowance. The plugs connect only to 2.4GHz Wi-Fi, much like the TOPELER pair, but Emporia supplies four outlets rather than two. Choose it when multi-room monitoring matters more than higher current capacity; skip it for devices that exceed its continuous rating.
Pros:- Four plugs support multi-room energy monitoring
- Real-time tracking helps identify device-level usage
- App scheduling and remote control are included
- Works with Alexa and Google Assistant
Cons:- 10A continuous limit is lower than the 15A Tapo P115 plugs
- Only supports 2.4GHz Wi-Fi

- Voice assistants:Amazon Alexa, Google Assistant
Our verdict“Choose Emporia for four-room coverage on lower-draw devices, but pick a 15A option such as Tapo P115 for compatible heavier loads.”
Smart Plug Outlet with Energy Monitoring, 15A, 2.4 GHz Wi-Fi, 4-Pack
This four-pack suits buyers who want to monitor and schedule compatible appliances in several places through one SmartLife app. Real-time power tracking gives a view of connected-device use, while timers, schedules, and group control make routine switching easier. Each plug supports 15A/1800W, matching the stated capacity of the Tapo P115 options; unlike Tapo, the product data here lists group control and short-circuit protection but does not describe smart charging cutoffs or energy charts. Its compact design helps preserve neighboring outlets. The setup tradeoff is notable: it uses 2.4GHz Wi-Fi, requires SmartLife, and needs manual linking of third-party services before voice control works. This is a straightforward multi-plug pick for app-based control, but Tapo offers more described energy and charging tools.
Pros:- Four plugs support monitoring across multiple devices
- 15A/1800W capacity matches the stated Tapo P115 rating

- Maximum current:15A
- Maximum power:1800W
- Connectivity:2.4GHz Wi-Fi
- App:SmartLife
- Voice assistants:Amazon Alexa, Google Assistant
- Hub required:No
- Certification:FCC
Our verdict“Choose this four-pack for SmartLife group control and 15A capacity, while Tapo P115 is the stronger fit for buyers prioritizing charging cutoffs and detailed charts.”
Tapo P110M Smart Plug (4-Pack), Matter Compatible, Energy Monitoring, 15A
The Tapo P110M makes the most sense when you want energy monitoring across a home that uses more than one smart-home platform. Matter support covers Alexa, Apple HomeKit, Google Home, and SmartThings, giving it broader platform flexibility than the Wi-Fi-only Tapo P115. Its bill estimates and off-peak schedules also connect usage data to practical choices, such as shifting a high-draw device to a cheaper time window. The four-pack suits buyers tracking several appliances at once. The tradeoff is that richer monitoring features run through the Tapo app, and some platform setups may need a Matter controller. If precise published measurement accuracy is your priority, the THIRDREALITY Gen3 states ±1% accuracy while the P110M does not provide an accuracy figure here.
Pros:- Matter certification supports four major smart-home ecosystems
- Energy tracking includes bill estimation
- Programmable schedules can shift device use to off-peak hours
- Four plugs make it practical to monitor multiple appliances
Cons:- Advanced monitoring features require the Tapo app and 2.4GHz Wi-Fi

Our verdict“Choose the Tapo P110M if you want a four-pack with Matter flexibility and energy tools that help connect usage to scheduling decisions.”
THIRDREALITY Smart Plug Gen3 (4 Pack) – Real-Time Power Meter, 15A Outlet, Zigbee Repeater, ETL Certified
The THIRDREALITY Smart Plug Gen3 is the clearest fit for buyers who already run a Zigbee network and want a stated measurement benchmark: ±1% power-monitoring accuracy. That precision sets it apart from the Tapo P110M, whose supplied specs do not state an accuracy figure, while the P110M offers Matter and Wi-Fi flexibility for homes without a Zigbee hub. Each THIRDREALITY plug also acts as a Zigbee repeater, so adding outlets can help extend mesh coverage as well as track appliance draw. Its compact shape is useful where adjacent sockets matter. The main limitation is the hub requirement; compatibility depends on supported Zigbee equipment. Power-on state restoration is also limited to the THIRDREALITY Hub Gen2 and Home Assistant.
Pros:- Real-time power monitoring specifies ±1% accuracy
- Built-in Zigbee repeater can extend mesh coverage
- Compact design avoids blocking adjacent sockets
- Four-pack supports monitoring several devices
Cons:- Requires a compatible Zigbee hub to operate
- Power-on state restoration has limited hub support
- Zigbee compatibility depends on having supported hub hardware
Best for: Home Assistant, SmartThings, Hubitat, or compatible Echo users who already have a Zigbee hub and want closely specified power measurements
Not ideal for: Wi-Fi-only smart-home users or buyers who need power-on state restoration through a hub other than THIRDREALITY Hub Gen2 or Home Assistant
- Pack size:4 plugs
- Connectivity protocol:Zigbee 3.0
- Operating voltage:110V

- Certification:ETL Certified
- Compatible devices:Echo (4th Gen), Echo Plus, Echo Show 8/10, Echo Studio, Eero 6/Pro 6, Home Assistant, SmartThings, Aeotec, Hubitat, Homey, THIRDREALITY Hub
- Control method:Remote, voice
- Mounting type:Plug-in
Our verdict“Pick the THIRDREALITY Gen3 if you have a compatible Zigbee hub and value stated monitoring accuracy plus mesh-network extension.”
How We Picked
I compared the 12 plugs on the factors that affect day-to-day usefulness: energy data and app controls, setup requirements, smart home compatibility, rated capacity, plug size, and pack format. A monitoring feature is only useful if the readings are easy to find and interpret, so I treated tracking and control as central to the ranking rather than as a checkbox. I also considered whether a model’s connectivity adds practical flexibility or calls for an existing hub or compatible platform.
The order favors plugs that balance useful monitoring with an approachable setup and clear buyer fit. That places the Kasa KP115 near the top as a broadly accessible single-plug choice, with Tapo P115 packs appealing to buyers outfitting multiple outlets. Matter and Zigbee models rank well for the smart home systems they serve, while specialized connectivity, less familiar brands, or a generic listing call for closer compatibility checks. Pack count alone does not determine rank: the right option depends on how many appliances you want to track and whether the monitoring tools suit your routine.

Factors to Consider When Choosing Smart Plugs With Energy Monitoring
I’d narrow the choice by starting with your appliances and smart home setup, then checking how you’ll use the energy data. These factors can prevent a plug that looks suitable on paper from becoming an awkward fit at home.
Match the Plug to the Appliance Load
Check the plug’s rated current and power against the appliance label or manual before connecting it. A 15A rating is common across this roundup, but it does not mean every plug suits every appliance or electrical setup. High-draw devices can approach a plug’s limit, especially when several appliances share an outlet or circuit. Avoid using a smart plug with equipment whose manufacturer disallows switched power, or where an unexpected shutoff could cause a problem. Leave headroom instead of treating the maximum rating as a normal operating target. If you are unsure about the load or wiring, ask a qualified electrician.
Pick a Protocol That Fits Your Home
Wi-Fi plugs are often the simplest route when you want app control without adding a hub, but confirm whether the model needs 2.4GHz, 5GHz, or supports both. Matter can make it easier to bring a plug into a compatible smart home platform, though you should check which controller and features your setup supports. Zigbee plugs can be a good fit for an existing hub-based network, and some can extend that network as repeaters. Buying for a protocol you do not currently use may add setup steps or require extra hardware. Check compatibility at the platform level, including whether energy readings appear there or only in the maker’s app. Choose based on the system you actually use every day.
Decide What You Need Energy Data to Tell You
Energy monitoring can mean a live power reading, a running consumption total, historical charts, or estimated operating costs. Decide which view would change your choices before comparing apps. If you want to spot a device that keeps drawing power, live readings may be enough; budgeting or comparing usage over time calls for history and clear units. Cost estimates depend on the electricity rate entered, so an inaccurate setting can make a precise-looking figure misleading. Check whether the app lets you review data over useful periods and export or share it if that matters to you. A plug that reports a number but makes trends hard to find may offer little practical help.
Buy the Pack Size You Can Put to Work
Multi-packs make sense when you already know which appliances you plan to track, such as a desk setup or several lamps. They can also leave you with unused outlets if your monitoring plan is still a guess. Start by listing devices and separating those whose consumption is useful to measure from those that only need remote switching. Remember that one plug typically measures the appliance attached to it, not everything on a shared power strip. A two-pack can be a sensible trial before standardizing on a four-pack. Keep plugs clear of neighboring sockets when their shape could block access.
Separate Monitoring From Energy Savings
A smart plug measures and controls power; it does not automatically lower consumption. Savings depend on what you learn from the readings and whether you change schedules or shut devices off. Some appliances need power to preserve settings, remain reachable, or complete updates, so automation can create inconvenience. Choose a timer or schedule only when it matches the device’s recommended use. For standby loads, compare the energy used with the effort and disruption of switching the device off. Treat the monitor as a source of information, then decide whether that information supports an action.
Check the App and Privacy Details Before Scaling Up
Whichever ecosystem you choose, check how an app handles accounts, device sharing, notifications, and remote access. These details matter more when you install several plugs and expect other household members to manage them. Look for clear units, understandable history, and controls that do not bury routine tasks. Review the manufacturer’s support and update information, since connected devices rely on software after installation. If you prefer local control or want to limit cloud dependence, confirm that the exact model supports it; protocol labels alone do not promise local energy reporting. Starting with one plug lets you judge the app before building a larger setup.
Frequently Asked Questions
Can I compare energy readings from different smart plug brands?
You can compare readings most fairly when both plugs measure the same appliance under similar conditions and report the same unit and time period. App estimates for electricity cost may differ if their rate settings are different. Small measurement differences can also come from the plugs’ sensing methods and the appliance’s changing power draw. For a useful comparison, focus on broad usage patterns rather than treating tiny differences as definitive. Check whether each app provides historical totals in a format you can review consistently.
Will a Matter smart plug show energy data in every smart home app?
Matter compatibility can help a plug join compatible smart home platforms, but the features exposed can vary by plug, platform, and controller. Energy readings may appear in the manufacturer’s app even when a third-party app offers only basic on/off control. Check the product’s supported platform details and the controller’s feature support before buying. If monitoring is your main reason for choosing Matter, verify energy reporting specifically rather than relying on the protocol name alone. That check can prevent a cross-platform setup from losing the feature you wanted.
Is one smart plug enough to measure several devices on a power strip?
A plug generally reports the combined power draw of whatever is connected downstream, so a strip can give you a group total. That reading will not tell you which device accounts for each part of the consumption. Avoid exceeding the smart plug’s load rating, and check that the appliances are suitable for switched power. If you need to identify a particular device’s usage, monitor it separately with its own plug. Group measurement works best when the devices are normally used together.
Should I choose a two-pack or a four-pack if I’m new to energy monitoring?
A two-pack is a lower-commitment way to learn whether the readings influence your decisions and whether you like the app. Pick two appliances with distinct use patterns so the data gives you a meaningful comparison. A four-pack makes more sense when you already have several specific devices to monitor and know the plugs work with your network. Unused plugs can become clutter, while buying too few may make it harder to compare a whole room or setup. You can also start with one model and add matching units after confirming the experience suits you.
Can I use an energy-monitoring smart plug with a refrigerator or other appliance that must stay on?
Monitoring a continuously powered appliance may be useful, but confirm that the appliance maker permits an external switched outlet. A smart plug can cut power during a schedule, automation, network issue, or accidental tap, which may interrupt operation. A refrigerator also has a motor load, so check the plug’s suitability for that appliance type and its electrical requirements. If you only need consumption data, avoid creating automations that could switch the outlet off. When the consequences of interruption are significant, use a monitoring method approved for that appliance instead.
Conclusion
For a broadly useful starting point, I recommend the Kasa KP115 as best overall, with the Tapo P115 two-pack as best value for buyers who want to monitor a pair of appliances and the four-pack for a larger rollout. The Kasa Matter KP125MP4 or Tapo P110M makes more sense as a premium-style pick for shoppers prioritizing Matter compatibility and a multi-plug setup; check the exact platform’s energy features first. For beginners, I’d start with one familiar Wi-Fi plug and add more only after the app and readings prove useful. Choose THIRDREALITY Gen3 for a Zigbee network, or consider the NOUS A9 if 5GHz connectivity is a specific fit for your setup. Govee and Emporia are worth comparing when several outlets matter most; prioritize the plug whose app, protocol, and electrical rating suit the appliances you plan to track.
