If you've never bought a smart-home product, this is the right first purchase. A four-pack of smart plugs costs less than a single smart bulb and lets you make any lamp, fan, holiday light, or space heater scheduleable in under a minute.

After testing eight smart-plug brands over the last year — including two that ended up in our drawer of "almost good enough" — here are the three we actually keep in our outlets.

Best overall

Kasa Smart Plug Mini 4-Pack

Kasa Smart Plug Mini 4-Pack

4.7(218,483)
Budget

The first smart-home buy we recommend to anyone curious about it.

Best for: Coffee makers, holiday lights, space heaters

Pros

  • Tiny form factor
  • Reliable Wi-Fi
  • Real usage tracking

Cons

  • 2.4 GHz only
  • No Matter or Thread yet

Starting at

$30

Check on Amazon$30

The Kasa Smart Plug Mini is the smart plug we recommend most often, and the one we have plugged into more than a dozen outlets across our test homes. The Mini form factor doesn't block the adjacent outlet (unlike most competitors), the Wi-Fi connection is reliably persistent (we've had zero drops in 14 months), and the energy-monitoring is genuinely accurate (verified against a Kill-A-Watt meter).

The Kasa app is one of the few smart-home apps we don't actively dislike. The Alexa and Google Home integration works without re-pairing every few weeks (a problem we hit with cheaper brands).

What we love

  • Genuinely small form factor — fits two on a duplex outlet
  • Reliable Wi-Fi — no drops, no re-pairing
  • Real energy tracking (kWh accurate to within 3% in our testing)
  • Works with Alexa, Google Home, IFTTT, SmartThings

What to watch for

  • 2.4 GHz Wi-Fi only (no 5 GHz support)
  • No Matter or Thread yet (as of mid-2026)
  • Four-pack is the right buy — single plugs cost almost the same

Best for power-hungry appliances: Amazon Smart Plug

Amazon's first-party smart plug is a good fallback if you're deeply embedded in the Alexa ecosystem and don't need energy monitoring. It handles up to 15 amps (1,800 watts) and pairs in about 10 seconds via the Alexa app. We use them for space heaters and an outdoor patio circuit.

Best for the next era: Matter-over-Thread plug

If you're building a smart home with longevity in mind, a Matter-over-Thread plug (Eve Energy is the one we recommend) joins the new cross-platform Matter standard and works without depending on any single brand's cloud. Pricier per outlet, but the future-proofing is real.

Bonus pick: water leak sensors

Aqara

Aqara Water Leak Sensor 3-Pack

The $60 sensor that has saved more floors than any single item we recommend.

Best for: Under sinks, washing machines, and water heaters

Pros

  • Tiny battery-powered pucks
  • HomeKit + Alexa
  • Catches floods early

Cons

  • Requires the Aqara hub
  • 2-year battery

Starting at

$60

If you're already wiring up the smart-home stack, the highest-ROI add-on is a water leak sensor under every sink, the washing machine, and the water heater. The Aqara 3-pack is the one we recommend. It has saved more floors than any product we've reviewed.

Use-case ideas

  • Coffee maker: Schedule it to brew 15 minutes before your alarm.
  • Holiday lights: Sunset-on, midnight-off, no more outdoor timers.
  • Space heater: Cut power if you forget you left it on.
  • Stand lamp: Turn on with voice or motion when you walk in.
  • TV / game console: Hard-cut phantom power draw overnight.
  • Phone charger / desk fan / aquarium heater: Anything plugged in becomes scriptable.

What we no longer recommend

  • No-name "smart plugs" from unknown sellers. Safety risk and bricked-cloud risk.
  • Older Wemo Mini plugs. Belkin's cloud reliability has slipped in the past two years.

Frequently asked questions

What can I do with a smart plug?+

Schedule lamps, fans, holiday lights, and space heaters. Turn the coffee maker on with voice. Cut power to a TV when you leave the house. Track an outlet's energy use to find phantom drains. Anything plugged into the wall becomes scriptable.

Do smart plugs work without Wi-Fi?+

Most consumer smart plugs (Kasa, Wyze, Amazon Basics) need 2.4 GHz Wi-Fi to connect to the cloud and respond to voice or scheduling. Without Wi-Fi the plug still works as a manual switch. Matter-over-Thread plugs (a newer category) can work via a Thread border router without cloud connectivity.

Are smart plugs safe?+

Yes — when you buy UL-listed plugs from established brands (Kasa, TP-Link, Amazon, Wyze). Avoid no-name imports from random Amazon sellers; we have seen safety failures and fires reported on the cheap unbranded options.
