Away-Mode Lights, kWh Tracking or Matter? Smart Plugs Sorted by What You Need

As an Amazon Associate, we earn from qualifying purchases. This doesn’t change our recommendations or the price you pay.

A smart plug turns an ordinary outlet into one you can schedule, switch from your phone or control by voice. The best smart plug for you depends on three things: which assistant or app runs your home, whether you want to see how much power a device uses, and whether the plug lives indoors or out.

We compared six plugs from six brands, all sold by Amazon.com or the brand’s own store: Wi-Fi models for Alexa and Google Home, two Matter plugs, a Zigbee plug that needs a hub, and an outdoor plug with two outlets. For each we quote the listing’s load rating, connection type, energy monitoring and any safety certification it names, and we flag what’s missing.

Smart plugs are handy for safety, too: lamps on a schedule while you’re away, and a quick way to cut power to a device you forgot. They are not for every load, though. Space heaters belong directly in a wall outlet, and we explain why below.

1. Kasa KP125M Matter Smart Plug, 4-Pack: Best Overall

Kasa’s KP125M is a compact indoor smart plug sold here as a four-pack, and it combines two features that often come separately: Matter compatibility and energy monitoring. Plug it into a wall outlet, plug a lamp, fan or appliance into it, and you can switch that device from an app, by voice or on a schedule.

Matter is the headline. Kasa says the plug works with Matter-certified platforms such as Apple Home, Amazon Alexa, Google Home and Samsung SmartThings, and that once configured, Matter devices on your local network keep working together even if your home internet goes down. You can also use the free Kasa app or voice commands through Siri, Alexa, Google Assistant or SmartThings.

Energy monitoring tracks usage over time, which Kasa says helps you understand consumption patterns. The title rates the plug at 15A and 1800W maximum, and the listing describes a “UL certified flame retardant design” in a compact body that avoids blocking the second outlet. The listed size is 2.62 by 1.57 by 1.5 inches, and the warranty field reads two years.

It suits homes that mix assistants, households that want to see what a dehumidifier or entertainment center draws, and anyone who wants four plugs to spread across lamps for an away-mode lighting routine.

Why we like it

• Matter across major platforms
• Built-in energy tracking
• Two-year warranty field

Watch out for

It is an indoor plug, and the listing doesn’t say which Wi-Fi band it needs, so check the setup notes if your router splits 2.4 and 5 GHz.

2. Amazon Smart Plug: Best for Alexa

Amazon’s own Smart Plug does one job simply: it adds Alexa voice and app control to an outlet. There’s no hub and no separate app. You plug it in, open the Alexa app and follow the setup directions, which Amazon says take minutes.

Day to day, you can say “Alexa, turn on the lamp,” tap a switch in the app, or build a routine. Amazon pitches it as a timer for lights and a way to create lighting schedules for when you are away from home, and with Alexa+ you can describe a routine in plain language. Routines can tie it to everyday tasks such as turning on a light or brewing coffee.

The listing says it works with lamps, fans, coffee makers and other household devices that have a physical on/off switch, which matters: a smart plug only cuts and restores power, so the device must come back on by itself. Amazon also says the plug automatically reconnects to Alexa after power or Wi-Fi outages, and the compact design leaves the second outlet free. The listing doesn’t give an amp or watt rating or name a safety certification, so check the label on the plug against the device you connect.

It suits Echo owners who want the easiest possible start with one plug, such as a living room lamp on an evening schedule.

Why we like it

• Setup lives in the Alexa app
• Away-mode lighting schedules
• Leaves the second outlet free

Watch out for

The listing names Alexa only and states no load rating, so it isn’t a pick for Google Home or for anything that draws heavy power.

3. Tapo P400M Matter Outdoor Smart Plug: Best Outdoor Smart Plug

Tapo’s P400M plugs into an outdoor outlet and gives you two separately controlled sockets for string lights, landscape lighting or decorations. Tapo says it was named Best Outdoor Smart Plug by Wirecutter in 2026, a claim from the listing that cites its dual outlets, IP65 weather resistance and Matter support.

Weatherproofing is listed as IP65, and Tapo says it works in the garden, patio or backyard and withstands rain, snow and dust, with an operating range of -4 to 122 degrees Fahrenheit. An included mounting screw and stabilizing post hold it to the outlet so it doesn’t wobble when you plug and unplug cords.

For control, it supports Matter, so it works with Apple Home, Alexa, Google Home and SmartThings, plus the Tapo app and voice through Alexa, Siri or Google Assistant. Dual antennas, Tapo says, push the signal up to 300 feet in an open field and 164 feet through three concrete walls, which helps when the router is far from the yard. Schedules and timers can bring the patio lights on at dusk, and groups let you set a scene across several devices.

It suits homeowners who want outdoor lights on a schedule, including while they’re away, and who use more than one smart home platform.

Why we like it

• Two outlets, controlled separately
• IP65 and a wide temperature range
• Long-range Wi-Fi claim

Watch out for

The listing gives no amp or watt rating, so check the plug’s label before connecting anything beyond lights and small decorations.

4. Govee H5086 Energy Monitoring Smart Plug, 4-Pack: Best Energy Monitor for Google Home

Govee’s H5086 four-pack is built for people who want numbers. Each plug tracks the real-time power, current and voltage of whatever is plugged into it, and the Govee Home app lets you review that data by day, week or month, going back up to a year.

Connection runs over Wi-Fi and Bluetooth. Govee says Bluetooth makes local control easy, while Wi-Fi lets you switch devices remotely, so you don’t come home to a dark house. The listing notes the plug does not support 5 GHz Wi-Fi, so it needs a 2.4 GHz network. Voice control works through Alexa and Google Assistant, and schedules can be set to the minute.

On safety, the listing says the plug is FCC and ETL certified and made of fire-resistant materials, and it rates the outlet at 15A and 120V. Govee suggests it for higher-power appliances such as a coffee maker. Group control lets you switch several plugs at once with one tap, and you can share control with family members on their own phones through the Govee Home app.

It suits households that want to find out what an old freezer, a gaming setup or a dehumidifier really draws, especially in homes run on Google Assistant or Alexa.

Why we like it

• Year-long energy history
• Wi-Fi plus Bluetooth
• ETL listed on the page

Watch out for

It doesn’t list Matter or Apple Home support, and it needs a 2.4 GHz network.

5. THIRDREALITY Smart Plug Gen3, 4-Pack: Best Zigbee Smart Plug

THIRDREALITY’s Gen3 plug skips Wi-Fi entirely and talks Zigbee 3.0, the low-power mesh protocol used by many smart home hubs. That means you need a hub. The listing names a long list: Echo models with built-in Zigbee hubs (such as the Echo 4th Gen and Echo Show 10), Eero 6, Home Assistant (ZHA and Z2M), SmartThings, Aeotec, Hubitat, Homey and THIRDREALITY’s own hub and bridge.

Each plug also acts as a Zigbee repeater. THIRDREALITY says an upgraded chip, enhanced RF module and optimized relay algorithm extend range and strengthen the mesh, which helps sensors far from the hub stay connected.

Power monitoring is the other draw. The brand says it is calibrated for ±1% detection accuracy and is supported by Home Assistant, SmartThings, Hubitat, THIRDREALITY Smart Hub Gen 2 and Bridge MZ1, with over-the-air updates on some platforms. A safety setting lets you choose whether the plug comes back on or stays off after power returns, currently supported on THIRDREALITY Hub Gen2 and Home Assistant. The title lists a 15A outlet and ETL certification, and the warranty field reads one year.

It suits tinkerers running Home Assistant or Hubitat and households that want plugs that won’t crowd the Wi-Fi network, with voice control through a compatible Echo or hub.

Why we like it

• Strengthens the Zigbee mesh
• Precise power readings
• Choice of power-on state

Watch out for

Without a compatible Zigbee hub it won’t work, and some features depend on which hub you use.

6. Linkind Matter Smart Plug, 4-Pack: Best Matter Plug for Apple Home

Linkind’s Matter Smart Plug comes as a four-pack and is built to drop into whichever platform you already use. Matter lets you add it straight to Apple Home, Alexa, Google Home or SmartThings without first creating an account in the maker’s app, and voice control works through Siri, Alexa, Google Assistant and SmartThings.

There’s a catch spelled out in the listing: those platforms need a Matter-certified hub or controller, such as a HomePod, an Echo, a Nest device or a SmartThings hub. Without one, you can control the plug directly in Linkind’s AiDot app. The plug only supports 2.4 GHz Wi-Fi and needs an IPv6 network. Once set up, Linkind says Matter devices on your LAN keep talking to each other even if the internet goes down.

Day to day, the remote control and schedules cover the usual jobs: turning a lamp on before you get home, or switching a holiday tree, TV, fan or humidifier off after a set time. The listing rates the plug at 1800W and 15A and says it uses fire-resistant materials with protection against short circuits and overloads. Its only named certification is FCC.

It suits Apple Home users who want Siri and Home app control of several lamps, and anyone setting up a Matter home on a budget.

Why we like it

• Works in Apple Home through Matter
• Local control during internet outages
• Four plugs per pack

Watch out for

Plan on a Matter controller for Apple Home, Alexa or Google Home, and a 2.4 GHz network with IPv6.

How We Chose the Best Smart Plugs

We limited the list to plugs that were in stock and sold by Amazon.com or the brand’s own store, took one plug per brand, and compared what each listing states:

• Load rating: the amp and watt figures, only where the listing gives them.
• Connection: Wi-Fi, Bluetooth, Matter or Zigbee, and whether a hub or controller is required.
• Assistants: Alexa, Google Home, Apple Home and SmartThings support as listed.
• Energy monitoring and schedules: what the plug measures and how far back the data goes.
• Safety marks and warranty: UL, ETL or FCC only when named, plus the warranty field and sales rank.

Every pick landed in our lowest price tier, so this guide sorts by features rather than budget.

Smart Plug Buying Guide

Best Smart Plug for Alexa vs. Best Smart Plug for Google Home

Start with the assistant you already use. The Amazon Smart Plug is set up in the Alexa app and its listing names only Alexa. The Govee H5086 lists Alexa and Google Assistant. The Kasa KP125M, Tapo P400M and Linkind support Matter, which covers Alexa, Google Home, Apple Home and SmartThings. The THIRDREALITY plug works with Alexa through Echo models that have a built-in Zigbee hub, or through other Zigbee hubs.

Best Matter Smart Plug: Wi-Fi, Matter, Thread or Zigbee?

Most smart plugs connect over Wi-Fi, and many need a 2.4 GHz network; the Govee and Linkind listings say so outright. Matter is a shared standard that lets one plug work across platforms. Kasa and Linkind both say Matter devices keep working on your local network if the internet drops, and Linkind notes you need a Matter controller such as a HomePod, Echo or Nest device for the big platforms. None of our picks lists Thread. Zigbee, used by the THIRDREALITY plug, needs a hub but stays off your Wi-Fi network.

Best Smart Plug With Energy Monitoring

Three picks measure power. Govee tracks power, current and voltage with history up to a year, THIRDREALITY claims ±1% accuracy on supported hubs, and Kasa tracks usage over time. Energy data helps you spot devices that draw power around the clock and confirm a schedule is doing its job. The Amazon, Tapo P400M and Linkind plugs don’t list energy monitoring.

Best Outdoor Smart Plug: Read the IP Rating

Indoor plugs are not built for rain. The Tapo P400M lists an IP65 rating and a -4 to 122°F operating range, plus two outlets you can control separately. Plug outdoor gear into a covered outdoor outlet and keep connections off the ground.

Load Limits: What Not to Put on a Smart Plug

A smart plug is only as strong as its rating. Kasa and Linkind list 15A and 1800W, Govee lists 15A at 120V, and THIRDREALITY lists a 15A outlet; the Amazon and Tapo listings give no rating, so read the label on the plug itself. Check the watts on the device’s label, and don’t pair a plug with anything that comes close to its limit. Space heaters are the big one: the U.S. Fire Administration’s space heater safety tips say to plug space heaters directly into wall outlets and never into an extension cord or power strip, and its heating fire safety page says to turn space heaters off when leaving the room or going to bed. Don’t put a heater on a smart plug unless the heater’s maker permits it and the plug’s rating covers it. Our space heater guide covers tip-over and overheat features. A smart plug is also not a surge protector; for TVs and computers, see our best surge protector picks.

Smart Plugs, Away Mode and Outlet Safety

Lamps that switch on and off on a schedule make an empty house look lived in, and the Amazon listing pitches exactly that: lighting schedules for when you’re away. Energy-monitoring plugs can also show whether something was left running. The USFA’s appliance and electrical fire safety page adds basics that apply to any plug: don’t overload outlets, insert plugs fully, replace wall outlets if plugs don’t fit snugly, and plug major appliances directly into a wall outlet.

• Test older outlets before adding plugs; our best outlet tester guide shows how.
• Use smart plugs for lamps, fans and small electronics, within the listed rating.
• Check a plug that feels warm or loose in the outlet, and stop using it.

Electrical Fires and Your Homeowners Insurance

Smart plugs can help you notice problems, but they don’t replace safe wiring or common sense. How a policy handles an electrical fire, damage from a faulty device, or theft while you’re away depends on your policy and insurer, so ask your agent. Some insurers may ask about smart home devices; ask your agent whether yours does. Our Ohio homeowners insurance guide covers the basics, and renters can start with renters insurance costs in Ohio.

Frequently Asked Questions

What is the best smart plug for most homes?

The Kasa KP125M is our top pick. It supports Matter for Apple Home, Alexa, Google Home and SmartThings, adds energy monitoring, lists a 15A/1800W maximum and a UL certified flame retardant design, and carries a two-year warranty field. Amazon.com sells it.

Which smart plug works best with Alexa?

The Amazon Smart Plug is the simplest Alexa choice: no hub, setup in the Alexa app, and lighting schedules for when you’re away. It ranks #1 in Smart Plugs. Its listing doesn’t state an amp or watt rating, so check the plug’s label for heavier loads.

Can I plug a space heater into a smart plug?

Generally, no. The U.S. Fire Administration says to plug space heaters directly into wall outlets, never into an extension cord or power strip. Only consider it if the heater’s maker permits it and the plug’s listed rating covers the heater, and still turn heaters off when you leave the room.

Do smart plugs work on 5 GHz Wi-Fi?

Not the ones that say otherwise. The Govee listing says it doesn’t support 5 GHz Wi-Fi, and Linkind says its plug only supports 2.4 GHz and IPv6. If your router combines bands, check the maker’s setup notes before installing.

What is the best outdoor smart plug?

The Tapo P400M lists an IP65 rating, a -4 to 122°F operating range, two independently controlled outlets and Matter support. Its listing doesn’t give an amp or watt rating, so check the label before connecting anything heavier than lights.

The Bottom Line

The Kasa KP125M is the best smart plug for most homes, pairing Matter with energy monitoring and a listed 15A/1800W rating. Echo owners can keep it simple with the Amazon Smart Plug, the Tapo P400M handles patio and holiday lights, the Govee H5086 gives the deepest energy history for Google and Alexa homes, the THIRDREALITY Gen3 suits Zigbee hubs, and the Linkind four-pack brings Matter to Apple Home on a budget. Whatever you buy, keep space heaters and other heavy loads in the wall outlet.
