If you only buy one smart plug, buy the meross MSS315: it’s Matter-certified, it tracks real energy use in a single app, and it costs less per plug than its more famous rival from TP-Link. Budget shoppers do almost as well with the Wyze Plug, which costs roughly a third as much and pays for itself in under five months by the math we run below. The other three plugs here — from Amazon, Govee, and Kasa — earn their keep in narrower situations we’ll walk through one at a time.
The reason any of this matters: “vampire power” — the electricity devices draw while idle — costs the average US household $165 a year, according to NRDC’s Home Idle Load research, and accounts for roughly 23% of residential electricity use. Energy Star puts the figure at more than $100 a year per household. A smart plug that auto-shuts a device on a schedule attacks that number directly. Below, we ran the actual payback math nobody puts on the box.

How the five smart plugs compare
Every plug here handles the same 15A/1,800W US household load and runs on 2.4GHz Wi-Fi only — none of them will join a 5GHz-only network, so check your router’s band settings before you buy any of the five. The real differences are ecosystem support and whether energy monitoring exists at all.
| Smart plug | Typical price | Energy monitoring | Apple Home | Alexa | Google Home | Matter |
|---|---|---|---|---|---|---|
| meross MSS315 | ~$13.25/plug (4-pack, $52.99) | Yes, in-app | Yes | Yes | Yes | Yes |
| Wyze Plug | $6.25–$7.50/plug | No | No | Yes | Yes | No |
| Kasa KP125M | $16.50–$20/plug | Yes, Kasa app only (not via Matter) | Yes | Yes | Yes | Yes |
| Amazon Smart Plug | $12.99–$24.99 | No | No | Yes | No | No |
| Govee Smart Plug Pro | ~$30.99 | Yes, in-app | No | Yes | Yes | No |
The vampire-power payback math
Here’s the number the packaging never shows you. NRDC’s Home Idle Load research puts average household standby power waste at $165 a year — spread across dozens of devices, not one outlet. So we built a deliberately conservative model: assume a single smart plug’s auto-off schedule eliminates just 10% of that household total, or about $16.50 a year ($1.38 a month). That’s not a guarantee of savings; it’s a consistent yardstick for comparing five products against the same assumption.
| Smart plug | Typical price per plug | Months to pay for itself* |
|---|---|---|
| Wyze Plug | $6.25 (4-pack) | ~4.5 months |
| Amazon Smart Plug | $12.99 (sale price) | ~9.4 months |
| meross MSS315 | $13.25 (4-pack) | ~9.6 months |
| Kasa KP125M | $16.50 (4-pack) | ~12 months |
| Govee Smart Plug Pro | $30.99 (single) | ~22.5 months |
*Based on the conservative 10%-of-NRDC’s-average assumption above. Treat the ranking as the takeaway, not the exact month count — a plug controlling a power-hungry entertainment cluster pays back faster than this table shows, and one controlling a phone charger pays back slower. Every plug on this list still earns back its price well within a normal 3–5 year service life, which is why the real decision below is fit, not whether.
Best overall: meross MSS315 Matter Smart Plug
The MSS315 is the only plug here that does both things well at once: it’s Matter-certified, so it genuinely works across Apple Home, Alexa, and Google Home without picking a side, and it tracks real-time energy use in the meross app without requiring a second, ecosystem-specific tool. At roughly $13.25 a plug in a 4-pack, it undercuts Kasa’s Matter-certified plug on price while matching it on certification and beating it on monitoring convenience.
The trade-off: it’s 2.4GHz Wi-Fi only, like every plug in this comparison, and reviewers have noted that Home Assistant’s Matter integration doesn’t yet expose its power-monitoring data — a niche caveat that only matters if you run a self-hosted smart home hub rather than Apple Home, Alexa, or Google Home. For the large majority of buyers using a mainstream platform, that gap doesn’t apply.
Best for: households that want one plug to work with whatever ecosystem they’re on today — or switch to tomorrow — without losing energy tracking.
Best budget: Wyze Plug
At $6.25 a plug in a 4-pack, the Wyze Plug is the cheapest way into scheduled, voice-controlled outlets, and it doesn’t feel cut-rate doing it: it supports Alexa, Google Assistant, and IFTTT, includes a vacation mode that randomizes on/off timing to look occupied, and setup takes about four minutes by most owner accounts. It’s also the fastest payback in our table above, purely because it costs so little to begin with.
What you give up: no energy monitoring at all, no Apple Home support, and no Matter certification, so it won’t graduate into a mixed-ecosystem household later. It also depends on Wyze’s cloud for app control and scheduling — most owners report reliable service with rare, brief hiccups, but there’s no local-only fallback if Wyze’s servers have a bad day.
Best for: Alexa or Google households buying in bulk — for a whole house of lamps and space heaters — where energy monitoring isn’t the point.
Best-known brand: Kasa KP125M
TP-Link’s Kasa line is the smart plug most people have already heard of, and the KP125M is its current Matter-certified, energy-monitoring model — UL Certified, compact enough not to block the second outlet on a duplex, and backed by one of the more polished apps in this category. It’s also the most widely stocked in physical stores, which matters if you want to swap a dead unit same-day.
The catch reviewers keep flagging: energy monitoring only surfaces in the separate Kasa app, not through Matter, so Apple Home or Google Home users who want wattage data still need to open a second app — which, as more than one reviewer has pointed out, undercuts the point of buying a Matter device in the first place. It’s also priced above meross for a nearly identical feature set.
Best for: buyers who want a nationally recognized brand with in-store support and don’t mind a second app for energy data.
Best for Alexa-only households: Amazon Smart Plug
If Alexa is the only smart home platform in the house, the Amazon Smart Plug is the least friction of any pick here: it sets up inside the Alexa app in minutes with no separate account, no hub, and no second app to learn. List price is $24.99, but it’s discounted to around $12.99 often enough that waiting for a sale is the default move, and it drops closer to $10 during major sales events.
The dealbreaker is right there in the name: it works with Alexa and nothing else. No Google Home, no Apple Home, no Matter, and no energy monitoring. Buy this one only if you’re certain Alexa is staying — an ecosystem switch later turns every unit into a plug that no longer talks to your house.
Best for: committed Alexa households who want the simplest possible setup and don’t need usage data.
Best single-app energy dashboard: Govee Smart Plug Pro
Govee’s Smart Plug Pro pairs Wi-Fi with Bluetooth, so the Govee Home app can manage it even if your Wi-Fi hiccups, and it tracks power usage without leaning on Matter or a second ecosystem app — a straightforward dashboard for Alexa and Google Assistant households who want to see real numbers, not just an on/off toggle. It’s ETL and FCC certified and needs no separate hub.
At roughly $30.99, it’s the most expensive plug in this comparison and, by our payback math above, the slowest to earn out — nearly two years under our conservative model. It also skips Apple Home and Matter entirely, so iPhone households should look at meross or Kasa instead.
Best for: Android/Alexa households that specifically want a built-in energy dashboard and are willing to pay a premium to get one without touching Matter.
What actually decides this purchase
Two things separate these five plugs, in order of importance. First: do you need energy monitoring, or just scheduling and voice control? If you just want lamps and fans on a timer, Wyze and Amazon do that job for a third of the price of the monitoring-capable plugs — energy data is a nice-to-have for most households, not a must-have. Second: does your household lean Apple, or mixed? Apple Home support is a hard line — only meross and Kasa cross it — while Alexa and Google Assistant are table stakes across almost every plug sold today.
What doesn’t decide it: Wi-Fi versus Wi-Fi-plus-Bluetooth (only Govee bothers, and it’s a minor convenience), or brand recognition alone — Kasa’s name recognition doesn’t buy you a feature meross doesn’t already have at a lower price. The one true dealbreaker across the board is band support: all five plugs need a 2.4GHz Wi-Fi network. If your router broadcasts a single, 5GHz-only SSID, fix that first, or none of these five will connect.
How we compared
We compared current, widely sold smart plugs on published specifications, certifications, and ecosystem compatibility, cross-checked against recurring patterns in verified owner reviews and long-term reliability reports rather than our own hands-on testing, which we don’t claim. Pricing reflects typical street prices at the time of writing and moves with sales — treat the price tiers, not the exact dollar figures, as the durable signal. Our payback table is arithmetic built on NRDC’s and Energy Star’s publicly reported vampire-power averages, disclosed as an assumption rather than a guarantee. Read more about how we work in our editorial standards. Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
Frequently asked questions
Do smart plugs actually save money on electricity?
They can, mainly by scheduling devices off instead of letting them idle. NRDC’s Home Idle Load research pegs average household standby waste at $165 a year, and a smart plug that cuts even a slice of that pays for itself within months, not years, as our payback table above shows.
Which smart plug works with Apple Home?
Of these five, only the meross MSS315 and the Kasa KP125M support Apple Home, both through Matter certification. Amazon’s, Wyze’s, and Govee’s plugs skip Apple Home entirely, so iPhone-first households have a two-plug shortlist.
Do smart plugs need a hub?
No. All five plugs in this comparison connect directly to a 2.4GHz Wi-Fi network and don’t require a separate smart home hub to function with their own app or with Alexa and Google Assistant.
What happens to a smart plug if my Wi-Fi goes down?
The physical outlet keeps working — anything already plugged in and switched on stays on — but app control, voice commands, and any cloud-dependent scheduling pause until the connection returns. None of these five plugs run schedules entirely offline.
Which smart plug has the best energy monitoring?
The meross MSS315 and Govee Smart Plug Pro both track usage well without needing a second app, but meross does it at less than half Govee’s price and adds Matter certification on top. Kasa’s KP125M also monitors energy, but only inside its own app, not through Matter.
Bottom line
Buy the meross MSS315 if you want one plug that works everywhere and actually shows you what it’s saving. Buy the Wyze Plug if price per outlet is the whole decision. Reach for the Kasa KP125M if brand recognition and in-store support matter more than saving a few dollars, the Amazon Smart Plug if Alexa is the only platform you’ll ever use, and the Govee Smart Plug Pro if a built-in energy dashboard matters more than Apple Home support.
