Best Smart Plug for Alexa (2026): 7 Picks, Matter and Wi-Fi

Amazon describes this plug as a no-hub device: plug it in, open the Alexa app and follow the steps. It needs a 2.4 GHz Wi-Fi network, and Amazon says it is for indoor use and for devices with a physical on/off switch, such as lamps, fans and coffee makers. After a power or Wi-Fi outage it reconnects to Alexa by itself, which removes a common smart plug annoyance.

The trade-off is reach. Amazon states that it works with Alexa and not with other voice assistants or hubs, so a household that mixes Alexa with an iPhone and Apple Home will outgrow it. Amazon does not publish a clear maximum load on the listing we found, so check the label before plugging in anything power-hungry.

For a bedroom lamp, a fan on a schedule or a pair of living room lights, it does the job with the least friction.

Skip it if you use Apple Home or Google Home, or want energy tracking; the Tapo P125M or Kasa KP125M fit better.

The P125M is the plug to buy when you want one device to belong to several smart home apps at once. TP-Link lists it as Matter certified, with Bluetooth setup in the Tapo app or a Matter code you can scan in the Alexa app. The datasheet gives 100 to 125V input and a 15A, 1800W maximum load at 120V.

Size is a quiet strength. Retail spec listings put it at roughly 1.3 by 1.5 by 2.4 inches, and reviewers note that it does not block the neighboring outlet. TechRadar's review framed it as an affordable way into Matter.

One thing to know: it is a Wi-Fi Matter plug, so it relies on your 2.4 GHz network and, for Alexa, a device that can act as a Matter controller. It does not report power use.

Skip it if you want to see how much electricity an appliance draws; the Kasa KP125M adds that.

The KP125M is the Matter version of TP-Link's energy-monitoring Kasa plug. It is rated for 15A and 1800W, and it measures how much power a connected device uses, then estimates the bill from a rate you enter. The 4-pack makes it practical to meter a window AC, a desktop PC, a dehumidifier and a TV setup in one go.

The catch, noted by BGR, is that you cannot use the energy monitoring in Apple Home, Google Home or Alexa, so the numbers live in the Kasa app. Alexa can switch the plug on and off, but it will not show watts. Keep the Kasa app set up if energy data matters to you.

Pairing it with a smart speaker and a few routines gives you both control and a clear picture of standby draw.

Skip it if you only need on/off control; the Tapo P125M does that for less hassle.

Holiday lights are the classic reason to buy an outdoor smart plug, because a timer you can edit by voice beats climbing out to a switch. TP-Link lists the P400M as IP65, with two independently controlled outlets and a combined 15A, 1800W rating. Tapo advises keeping it face down, about 12 inches off the ground and under its cover when not in use, so plan placement before you plug in.

Because it is Matter certified, you can add it to Alexa by scanning the code, and each outlet shows up as its own device. That is handy for lights on one side and a pump on the other. Tapo claims a range of up to 300 feet in open space, but walls and distance from your router still matter.

Check the wattage of your light strings, since LED sets draw far less than older incandescent ones.

Skip it if your outdoor outlet is far from Wi-Fi coverage; fix the signal first, perhaps with a [mesh Wi-Fi system](/tech/best-mesh-wifi-system/).

Eve takes a different route from the Wi-Fi plugs above. The US model, 20EBU4101, is Matter over Thread, which means it needs a Thread border router in the house. Eve's spec sheet lists a 15A, 1800W maximum and calls for iOS 16.4 or later, or Android 8.1 or later, for setup. Check that your Echo or other hub can act as a Thread border router before buying.

Thread plugs form a mesh, so each plug extends the network for the others. Eve also stresses local operation, with no cloud account or tracking. Retail listings put the body at about 2.8 by 1.5 by 2.4 inches, larger than the Tapo or Kasa minis.

Match the plug to your hub rather than the other way around.

Skip it if you have no Thread border router and just want Alexa control; the Amazon Smart Plug or Tapo P125M is simpler.

This is the Matter sibling of Amazon's own plug line. The listing says it works with Alexa, Apple Home and Google Home through Matter, requires a Matter-compatible hub and supports 2.4 GHz Wi-Fi only. During checkout you can link the device to your Alexa account to simplify setup.

9to5Mac's HomeKit Weekly column called it a possible new go-to plug because of the low cost, and noted that it works with an Apple hub such as a HomePod mini or Apple TV 4K over Wi-Fi. The same column points out the lack of Thread, a small complaint at this level.

We could not confirm the maximum load from a manufacturer source, so treat it as a lamp, fan and charger plug and check the label.

Skip it if you want a 15A rating you can verify before purchase; the Tapo P125M lists it clearly.

The MSS115 is a straightforward Matter plug, and it is the one on this list with the lowest published ceiling. TechHive's review gives the maximum output as 10 amps (1200 watts), against 15 amps for the P125M, so it suits lamps, string lights and chargers better than a window AC or a heater. The review lists the body at about 1.9 by 1.9 by 1.2 inches.

Meross listings describe local control over your LAN and Alexa pairing by asking an Echo to find the device, with traditional Matter pairing as the fallback. A separate MSS315 adds energy monitoring in some regions, but the US MSS115 does not include it.

Check the model number in the listing before buying, since Meross sells several plugs with similar names.

Skip it if you plan to run a coffee maker or anything near 1500 watts; choose a 15A plug like the Tapo P125M.
