Five of the six best smart plugs here carry a full 15 amps, so for a lamp, a fan or a small appliance the real choice is what each plug connects through. Get the Kasa EP10 for Alexa or Google Assistant, the Tapo P125M for Apple Home, the THIRDREALITY plug if you already run a Zigbee hub, and the Kasa EP40A for outdoors.

Using Alexa or Google Assistant? Two smart plugs with no hub
Both are smart plugs that work with Google Home and Alexa over your Wi-Fi, with no hub. Neither maker lists Apple Home for them, though. If your household runs from the Home app on an iPhone, a Matter plug is the better buy.
Kasa EP10: the default for most rooms
The Kasa EP10 is rated for 15 amps, 1,800 watts and a 1/6 horsepower motor. Four of the other five plugs share its 15-amp rating, and only the P125M and KP125M match all three numbers. Setup runs through the Kasa app on a 2.4GHz network. Once it’s in, Alexa or Google Assistant can switch it, and the app adds schedules, an auto-off timer and an away mode that turns things on and off to make the house look occupied.
It carries UL certification and comes as a two-pack. Buy it if you talk to Alexa or Google and want a bedside lamp or a box fan on a timer. Pass if Apple Home is your hub, because Kasa lists only Alexa and Google Assistant for this model.
GHome WP3: for a Smart Life or Tuya home, with a lower ceiling
The GHome WP3 tops out at 10 amps and 1,200 watts, a third less than the five 15-amp plugs here. That still leaves room for lamps and string lights, but anything labeled over 1,200 watts is off the table. It works with the GHome, Smart Life and Tuya apps. So if your bulbs or switches already live in Smart Life, this plug joins them instead of adding another app.
Alexa and Google Assistant only find it once the GHome app has put it on your home network. It needs 2.4GHz Wi-Fi, it can also connect over Bluetooth, and it meets ETL and FCC requirements. GHome publishes no motor rating, which is why a fan belongs on one of the TP-Link plugs instead. It comes as a four-pack, which also splits well into presents. For that, the smart home gifts guide matches each pick to the assistant the person already uses.
On Apple Home, or mixing assistants? The best smart plugs speak Matter
Both are Matter certified, so these smart plugs can work with Google Home, Alexa, Apple Home and SmartThings. For a household that mixes brands, these two are the safest bets. For how Matter compares with plain Wi-Fi and Zigbee, see Zigbee vs WiFi vs Matter.
Tapo P125M: the compact Matter pick
The Tapo P125M matches the EP10’s 15 amps, 1,800 watts and 1/6 horsepower. Its body measures 2.4 by 1.5 by 1.3 inches, and Tapo sized it to leave the neighboring socket free. Tapo’s spec sheet lists Apple Home, Alexa, Google Assistant and SmartThings alongside Matter. Bluetooth handles setup only. After that, the plug runs on 2.4GHz Wi-Fi.
Tapo’s datasheet says not to use it outdoors or in damp rooms, and it’s rated for 32°F to 104°F. Schedules, an auto-off timer and an away mode come built into the Tapo app. Get it if your home mixes an iPhone with an Echo in the kitchen, since one plug serves both. Skip it if you want power readings, because Tapo doesn’t list energy monitoring for this model.
Kasa KP125M: Matter with an energy meter
The Kasa KP125M adds what the P125M leaves out. Its app shows a connected device’s real-time and past power use, so you can see what a TV or a dehumidifier draws while it runs. Its load ratings are the same 15 amps, 1,800 watts and 1/6 horsepower, and it’s Matter certified with UL certification.
The trade-off is bulk. At 2.6 by 1.5 by 1.6 inches, it’s larger than the P125M. Like the P125M, it works with Alexa, Google Assistant and Siri for voice. Buy the KP125M when the numbers matter to you. If they don’t, the P125M switches the same loads in a smaller body.
Already have a Zigbee hub or the right Echo?
The THIRDREALITY Zigbee Smart Plug Gen2 speaks Zigbee 3.0, not Wi-Fi, so it does nothing without a hub. THIRDREALITY lists Echo models with a built-in Zigbee hub, including the Echo (4th Gen), the Echo Studio and the Echo Show 10 (2nd and 3rd Gen). It also lists Home Assistant, SmartThings, Hubitat and its own hubs. With one of those Echo models, setup means plugging it in and asking Alexa to discover your devices. That makes them smart plugs that work with Alexa without a separate hub, as long as your Echo is on the list. Google Home control comes through a Zigbee hub that works with Google.
Each plug repeats the Zigbee signal, so a four-pack spread through the house stretches the network’s range. The plugs also report power use, which shows up in Home Assistant, SmartThings, Hubitat and THIRDREALITY’s Hub Gen2. One setting stands out: you can choose whether a plug comes back on or stays off after a power cut. That choice works in THIRDREALITY’s Hub Gen2 and in Home Assistant through ZHA or Zigbee2MQTT.
It’s rated for 15 amps, but THIRDREALITY doesn’t publish a motor rating. Of the best smart plugs here, it’s the only one that won’t run on Wi-Fi alone, so buy it if you already run Zigbee. Without a hub, the EP10 does the same job with less fuss.
Smart plugs for the porch, patio or yard
The Kasa EP40A is the only one of the best smart plugs here made for outside. It’s rated IP64 against dust and splashing water and works from -4°F to 122°F. TP-Link puts its Wi-Fi reach at up to 300 feet in open areas. Its two outlets switch independently, so string lights and a porch lamp can go on and off separately.
The EP40A is rated for 15 amps, 1,875 watts and a 1/2 horsepower motor, the highest motor figure of the six. It works with Apple Home as well as Alexa, Google Assistant and SmartThings. It’s also the only one of these smart plugs with Apple HomeKit support built in rather than added through Matter. It needs 2.4GHz Wi-Fi, and it comes on a 6-inch cable with a clamp and a screw.
What to have ready before setup
Every one of the top smart plugs here sets up from a phone app, and the app depends on the brand. Kasa’s app covers the EP10, KP125M and EP40A, and Kasa’s listings say the Tapo app now supports them too. The P125M uses the Tapo app, the GHome uses GHome, Smart Life or Tuya, and the THIRDREALITY plug is added through your Zigbee hub or a Zigbee Echo.
Your network matters more than the app. The EP10, P125M, EP40A and GHome all need 2.4GHz Wi-Fi, and none of them joins a 5GHz-only network. If the Home app calls your network incompatible, Apple’s support advice is to check that your iPhone is on a Wi-Fi network that supports 2.4GHz. The P125M uses Bluetooth only during setup. The KP125M onboards over Bluetooth in the Kasa app, or you can add it by scanning its code in any Matter app.
Lamp, fan or coffee maker: can the plug carry it?
Even the best smart plugs have a ceiling. Read two numbers before you plug something in: the watts on the device’s label and, for anything with a motor, its horsepower. Then check them against the plug.
- Watts. The EP10, P125M, KP125M and THIRDREALITY plugs are rated 1,800 watts, the EP40A 1,875 and the GHome 1,200. For a load that runs continuously for long stretches, TP-Link asks you to stay at 80% or less of the rating on its Kasa and Tapo plugs. That works out to 1,440 watts on its 1,800-watt models and 1,500 on the EP40A.
- Motors. Motor-driven devices draw a surge at startup that can exceed a plug’s rated current. TP-Link rates each of its plugs in horsepower for that kind of load. If your fan’s label lists horsepower, keep it at or under 1/6 HP on the EP10, P125M and KP125M, or 1/2 HP on the EP40A.
- The worked case. Say your coffee maker’s label reads 1,500 watts. That’s over the GHome’s 1,200-watt maximum, so it can’t go there. It sits inside the 1,800-watt maximum on TP-Link’s three indoor plugs, and Tapo pitches the P125M for scheduling a coffee maker, kettle or toaster. But it’s over the 1,440-watt line TP-Link sets for continuous loads, so keep a 1,500-watt appliance to short runs, not hours on end.
A lamp only needs the watts check, since it has no motor. One exception: Tapo’s datasheet caps incandescent bulbs on the P125M at 8 amps, which is 960 watts at 120 volts. Heaters, irons and the outlet an outdoor plug needs each get a verdict in which devices are safe to plug in.
Smart plug FAQ
Do Apple HomeKit smart plugs need an Apple TV or HomePod?
Not to add the Matter plugs. Apple says an iPhone on iOS 18 or later can add and control Matter accessories without a home hub, though it recommends one. For the Kasa EP40A, TP-Link’s listing says Apple Home control from outside the house needs a HomePod or Apple TV at home.
Can Matter smart plugs work with Alexa and Apple Home at the same time?
Yes. A Matter plug such as the Tapo P125M or Kasa KP125M can be shared between apps. Apple’s instructions cover adding a Matter accessory that’s already paired with another app: you follow the second app’s steps for a new accessory. In Apple Home, that means tapping More options and picking the plug.
Will the Matter plugs keep working if my internet goes down?
Partly. TP-Link’s Amazon listings for the Tapo P125M and Kasa KP125M say Matter devices on the same home network keep talking to each other directly when the internet goes offline. Neither TP-Link product page makes that promise, and neither says app or voice control carries on during an outage.
