Two of the assumptions this page made about smart plugs are no longer true. Wyze was the cheapest, fastest-payback plug here. It isn’t anymore, at roughly $15 a plug instead of $6.25. Govee was the priciest and slowest to earn back its cost. It’s now the cheapest per plug of all five, once you buy it in the multi-pack its own store sells. Nothing about what these plugs do changed, only what they cost, and that’s enough to rewrite the ranking.
I have put smart plugs on lamps, a coffee maker and an entertainment shelf over the years, and the app matters more than the plug. A plug that needs a second app ends up back in the drawer.
Which Assumptions About These Smart Plugs No Longer Hold?
We checked each plug’s current price directly against its own manufacturer’s store. Then we cross-checked with a second retailer, before touching the payback math below. Two of the five had moved enough to matter.
| Plug | What this page said before | What the maker’s own store says now | Verdict |
|---|---|---|---|
| Wyze Plug | $6.25–$7.50 a plug, the cheapest option here | $14.99 a plug in the 2-pack ($29.98) or 4-pack ($59.96) on wyze.com, October 10, 2026 | No longer the budget pick on a per-plug basis |
| Govee Smart Plug Pro | ~$30.99 for a single unit, the priciest here | $7.50–$9.99 a plug in the 4-pack and 2-pack Govee itself now sells, per govee.com on October 10, 2026 | Now the cheapest per-plug price of all five |
| Kasa KP125M | Priced above meross for a similar feature set | $44.99 for a 4-pack (~$11.25/plug) at B&H, undercutting meross’s $13.25/plug | The price relationship reversed |
| “$165 a year” vampire-power figure | Cited without a date, reading like a fresh number | Traces to NRDC’s 2015 Home Idle Load study — still the most recent major research on the topic, but a decade old | Real number, needs its age stated plainly |
How Much Do These Smart Plugs Cost to Own?
NRDC’s 2015 Home Idle Load research put average household standby power waste at $165 a year. Energy Star’s own figure is a bit lower, over $100. Either way, it is spread across dozens of devices, not one outlet. We keep the same deliberately conservative model as before. Assume one smart plug’s auto-off schedule eliminates 10% of that household total, or about $16.50 a year ($1.38 a month). That’s a yardstick for comparing five products against the same assumption, not a promise of savings.
| Plug | Current price per plug | Months to pay for itself* |
|---|---|---|
| Govee Smart Plug Pro | $7.50 (4-pack) | ~5.5 months |
| Kasa KP125M | $11.25 (4-pack) | ~8.2 months |
| Amazon Smart Plug | $12.99 (common sale price) | ~9.4 months |
| meross MSS315 | $13.25 (4-pack) | ~9.6 months |
| Wyze Plug | $14.99 (2-pack) | ~10.9 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. One controlling a phone charger pays back slower. Every plug here still earns back its price well within a normal 3–5 year service life. The genuinely new information is the order. At this page’s earlier prices, the same table put Wyze first and Govee last.
Is meross Still the Best of These Smart Plugs?
The MSS315 is one of two plugs here doing two things well at once, along with the Kasa. It’s Matter-certified, so it works across Apple Home, Alexa, and Google Home without picking a side. It also tracks real-time energy use in the meross app without a second, ecosystem-specific tool. Kasa’s KP125M now undercuts it slightly on price and matches its Matter certification, which is worth knowing. But meross’s single-app energy dashboard and 2026 track record of not getting discontinued or repriced overnight make it the safer default. That suits someone who wants to buy once and stop thinking about it.
Best for: households that want one plug to work with whatever ecosystem they’re on today — or switch to tomorrow — without losing energy tracking. Skip this if you don’t care about energy data at all. You’re paying a few dollars more than Govee or Kasa for a feature you won’t use.
Does Kasa’s Price Drop Make It the New Budget Matter Pick?
TP-Link’s Kasa line is the smart plug most people have already heard of. The KP125M is its Matter-certified, energy-monitoring model. It is UL Certified, compact, and backed by one of the more polished apps in this category. At $44.99 for a 4-pack, it’s now the second-cheapest Matter-certified option here. That is a real change from when it cost more than meross for a similar feature set. It’s also the most widely stocked in physical stores, which matters if you want to swap a dead unit same-day.
Best for: buyers who want a nationally recognized brand with in-store support at a price that no longer carries a real premium over meross. Skip this if you’ve already standardized on the meross app for other plugs. There’s little reason to run two apps for the same job.
Should the Fastest Payback Change Your Pick?
Govee’s Smart Plug Pro pairs Wi-Fi with Bluetooth, so the Govee Home app can manage it even through a brief Wi-Fi hiccup. Govee’s own page for the current model, B5083, now lists Matter compatibility. It says nothing about energy or power monitoring, so do not count on a usage dashboard. What changed most is the price. Buying it in Govee’s own 4-pack brings it to $7.50 a plug, the lowest per-plug price in this comparison and the fastest payback of the five by our math. The page names Alexa and Google Assistant but not Apple Home, so iPhone households are safer with meross or Kasa.
Best for: Alexa or Google households that want the lowest per-plug price here. Skip this if you want energy tracking, which Govee’s page for this model does not list.
Who Should Still Buy the Wyze Plug at Its New Price?
At roughly $15 a plug, the Wyze Plug is no longer the impulse-buy price it was. It still supports Alexa, Google Assistant, and IFTTT. It includes a vacation mode that randomizes on/off timing, and it sets up in minutes by most owner accounts. What it still lacks — energy monitoring, Apple Home, Matter certification — hasn’t changed. Now it costs about as much as plugs that do have those features. It also depends on Wyze’s cloud for scheduling, with no local-only fallback.
Best for: Alexa or Google households already invested in the Wyze ecosystem for cameras or sensors. Skip this if price per plug is the deciding factor. Govee and Kasa now both undercut it while offering Matter certification or energy monitoring it doesn’t have.
Why the Amazon Smart Plug Stays the Alexa-Only Answer
If Alexa is the only smart home platform in the house, the Amazon Smart Plug remains the least friction of any pick here. It sets up inside the Alexa app in minutes, with no separate account and no second app to learn. List price is still $24.99, but it’s commonly discounted to around $12.99. The dealbreaker hasn’t moved. It works with Alexa and nothing else. There’s no Google Home, no Apple Home, no Matter, and no energy monitoring.
Best for: committed Alexa households who want the simplest possible setup and don’t need usage data. Skip this if there’s any chance you’ll add an Apple or Google device to the house later. Every unit you buy stops working the day you switch ecosystems.

Which Smart Plugs Should You Buy?
Buy the meross MSS315 if you want the plug most likely to still make sense in two years, whatever ecosystem you land on. Choose the Kasa KP125M if brand recognition and in-store support matter and you want to pay slightly less for nearly the same thing. The Govee Smart Plug Pro suits shoppers for whom price per plug matters more than energy data or Apple Home support. It earned that recommendation by getting cheaper, not by us changing our mind. Take the Wyze Plug only if you’re already in its ecosystem. Its price no longer does the arguing for it. Finally, the Amazon Smart Plug fits if Alexa is the only platform you’ll ever run.
