The Tapo P125M is the value Matter pick: one of the smallest plugs on the market and among the cheapest Matter-certified options, making it ideal for outfitting a whole house cheaply. PCWorld ranked it among its top smart plugs and Tom's Guide and CNET placed it at the top of their Matter roundups. The catch is no energy monitoring and Tapo-app-only control.
Full review
Real-World Performance
The Tapo P125M is TP-Link's bargain route into Matter. PCWorld, which ranked it among its top smart plug picks, summed up the appeal plainly: 'It's worth paying a little more for early Matter compatibility, the standard that's destined to be the future.' Because it's Matter-certified, Matter Alpha confirmed it pairs natively with Alexa, Google Assistant, SmartThings, HomeKit, and IFTTT — no bridge required. For a plug that often sells for under $20 (and far less per unit in multipacks), that breadth of support is hard to beat.
In normal use it does exactly what a smart plug should: respond quickly to app and voice commands and hold a stable connection. Matter Alpha did flag one wrinkle with Amazon Alexa specifically, noting the 'plug would become unresponsive randomly, leading to instances where the app would become out of sync with the device state if toggled through another platform.' That cross-platform state desync is a known Matter teething issue more than a hardware fault, but it's worth knowing if Alexa is your main controller.
Build Quality and Design
Size is the P125M's signature trait. Matter Alpha called out that 'the small size allows the P125 to provide its smart benefits without blocking other receptacles, and you can easily fit two on the same outlet if needed.' Reviewed described it as 'one of the smallest smart plugs you can buy right now.' That compactness makes it ideal for tight spaces — power strips, crowded kitchen counters, and behind furniture — where bulkier plugs would cover the second outlet.
The housing is simple white polymer with a side button for manual on/off. There's no dimming, no USB ports, and no outdoor rating; this is a focused indoor on/off plug. The build quality is consistent with TP-Link's reliable mainstream hardware, and the 15A/1800W rating handles typical household loads.
Setup and Software
Setup runs through the Tapo app, which handles Wi-Fi pairing and Matter commissioning. PCWorld and Matter Alpha both found the process quick and beginner-friendly. One important distinction from the Kasa line: the P125M is not compatible with TP-Link's Kasa app, only the Tapo app. If you already run a house full of Kasa gear, that means a second app — a small but real annoyance for managing everything in one place.
Once commissioned, you can control the plug from the Tapo app or from your chosen Matter ecosystem. Scheduling, timers, and away mode are all present. The software is straightforward rather than feature-rich, which suits the plug's budget positioning.
Where It Falls Short
The biggest omission is energy monitoring — PCWorld noted bluntly that 'the plug does not have any energy-monitoring features.' If tracking wattage matters to you, the Kasa KP125M is the better TP-Link choice. The P125M is also Wi-Fi only with no Thread radio, so it won't strengthen a Thread mesh, and like every Wi-Fi plug it consumes one of your 2.4GHz network slots.
The Tapo-app-only limitation and the occasional Alexa state-sync hiccup Matter Alpha observed round out the caveats. None are dealbreakers for the price, but they're the reasons this plug sits at value pick rather than best overall.
Value at This Price
Value is the entire argument for the P125M. It's frequently among the cheapest Matter-certified plugs available, and in multipacks the per-unit cost drops further. For someone deliberately building a Matter-first smart home on a budget — or simply someone who wants future-proof cross-ecosystem support without paying for energy monitoring they won't use — it's the most cost-effective way to get there.
Stacked against non-Matter budget plugs like the Wyze Plug, the P125M costs a little more but buys genuine cross-platform longevity. Matter Alpha's verdict captures the calculus: at roughly $20 it's 'one of the best Matter devices that you can buy for your smart home.'
How It Compares to Alternatives
The P125M's closest sibling is the Kasa Matter Smart Plug KP125M: both are Matter-certified TP-Link plugs with the same slim, non-blocking design, but the Tapo drops energy monitoring and the Kasa app in exchange for a lower price. If you want the cheapest path into Matter and don't care about wattage data, the Tapo wins; if you want the data, step up to the Kasa.
Compared to the non-Matter budget options, the Tapo costs a little more than the Wyze Plug but buys genuine cross-platform longevity — it works with Alexa, Google, Apple, and SmartThings out of the box, where the Wyze is Alexa/Google only and the Amazon Smart Plug is Alexa only. The Wemo Smart Plug with Thread is the only one here that offers Thread mesh, but it's Apple-exclusive, so the Tapo remains the most broadly compatible cheap plug in the group.
Who It's Best For
Choose the Tapo P125M if you want Matter certification at the lowest possible price and don't need energy data. It's the ideal plug for buying in bulk to automate lamps, fans, and seasonal devices across a whole house while staying future-proof. Its tiny footprint also makes it the best choice for power strips and crowded outlets where a bulkier plug would cover the second socket.
Look elsewhere if you want energy monitoring (the Kasa Matter Smart Plug KP125M), Thread mesh support (the Wemo Smart Plug with Thread), or the absolute cheapest single plug with no Matter requirement (the Wyze Plug or Amazon Smart Plug). For a budget Matter build that needs to talk to everything, though, the Tapo P125M is the smart default.
Strengths
- +One of the smallest Matter-certified plugs you can buy
- +Native support for Alexa, Google, Apple Home, SmartThings, and IFTTT
- +Excellent value — among the cheapest Matter-certified plugs
- +Slim body lets two fit on a single duplex outlet
- +No hub required; pairs directly into any Matter ecosystem
Watch-outs
- −No energy monitoring at all
- −2.4GHz Wi-Fi only, no Thread radio
- −Not compatible with TP-Link's own Kasa app (Tapo app only)
- −Some testers saw occasional Alexa state-sync hiccups
How it compares
The budget Matter alternative to the Kasa Matter Smart Plug KP125M — it drops the KP125M's energy monitoring to hit a lower price. It carries the Matter certification the Wyze Plug and Amazon Smart Plug lack, and unlike the Wemo Smart Plug with Thread it isn't tied to Apple Home.
