Best Smart Plugs and Outlets in 2026

Smart plugs are the gateway drug of home automation. For $10-25, you can make any dumb appliance smart — schedule your coffee maker, monitor your energy usage, turn off forgotten irons remotely, or set your Christmas lights on a timer. They're cheap, easy to install (literally plug and play), and surprisingly useful once you start.

We've tested dozens of smart plugs for reliability, app quality, Matter compatibility, and long-term performance. Here are the winners.

1. TP-Link Kasa Smart Plug (EP25P4) — Best Overall

Check price on Amazon →

The Kasa EP25P4 does everything a smart plug should do, and it does it reliably. Matter support means it works with Alexa, Google Home, and Apple HomeKit. Built-in energy monitoring tells you how much power each device uses. And the compact design doesn't block the second outlet — a surprisingly common problem with smart plugs.

What impressed us: Reliability over months of testing. Many smart plugs lose WiFi connection, fail to respond to voice commands, or forget their schedules. The Kasa EP25 stayed connected and responsive throughout our entire testing period. The energy monitoring feature is genuinely useful — we discovered a "sleeping" gaming PC was drawing 45 watts 24/7.

Pros:

• Matter certified (works with all major ecosystems)
• Energy monitoring built in
• Compact design doesn't block adjacent outlet
• Kasa app is well-designed with schedules, timers, and away mode
• 4-pack pricing brings per-plug cost to ~$6
• WiFi direct (no hub required)
• Reliable WiFi connection

Cons:

• 2.4GHz WiFi only (not 5GHz)
• No physical button on some models (must use app/voice to toggle)
• Energy monitoring accuracy is approximate (±5%)
• Kasa app requires account creation
• No USB-A or USB-C output

Bottom line: The best smart plug for most people. Reliable, affordable in multi-packs, and compatible with everything. This is what we use in our own homes.

2. Amazon Smart Plug — Best for Alexa Users

Check price on Amazon →

If you're already in the Alexa ecosystem and just want the simplest possible setup, the Amazon Smart Plug connects in about 30 seconds. Open the Alexa app, plug it in, and it auto-discovers. No separate app, no account creation, no fuss.

What impressed us: The setup experience is as close to frictionless as smart home gets. And because it integrates directly with Alexa routines, you can create complex automations without any third-party apps. "Alexa, good night" can turn off all your smart plugs, lock the doors, and set the thermostat in one command.

Pros:

• Fastest setup in the smart plug market
• Deep Alexa integration (routines, groups, voice control)
• Reliable and compact
• Often on sale for $10-12 during Prime events
• No separate app needed (Alexa app does everything)
• Works with Alexa's Frustration Free Setup

Cons:

• Alexa ecosystem only (no Google Home or HomeKit without workarounds)
• No Matter support
• No energy monitoring
• Requires an Echo device on your network
• No scheduling without Alexa app
• Not useful if you switch away from Amazon

Bottom line: The easiest smart plug if you're all-in on Alexa. But the ecosystem lock-in means it's worthless if you ever switch to Google or Apple. For broader smart home options, see our best smart home hubs guide.

3. Eve Energy — Best for Apple HomeKit (Thread)

Check price on Amazon →

Eve is the premium HomeKit brand, and the Eve Energy is the best smart plug for Apple households. It connects via Thread (not WiFi), which means faster response times, lower power consumption, and a mesh network that gets more reliable as you add devices.

What impressed us: Thread responsiveness is noticeably faster than WiFi smart plugs. Commands execute in under a second, even with multiple devices. The energy monitoring tracks usage over time with detailed charts in the Eve app, and all data is processed locally — nothing is sent to Eve's servers.

Pros:

• Thread/Matter certified
• Excellent energy monitoring with historical data
• Complete privacy (local processing, no cloud)
• Eve app is beautiful and detailed
• Native HomeKit integration
• No account required
• Compact design

Cons:

• Expensive (~$35 for a single plug)
• Requires HomePod Mini or Apple TV as Thread border router
• Apple-centric (Matter support helps, but Eve app is iOS-only)
• No physical toggle button
• Thread requires at least one border router device
• Not available in multi-packs at discount

Bottom line: The privacy-conscious Apple user's dream. Fast, reliable, and your data never leaves your home. But the premium price and Apple dependency make it a niche choice.

4. Meross Smart Plug (MSS110) — Best Budget Option

Check price on Amazon →

The Meross MSS110 is the cheapest Matter-certified smart plug available in multi-packs. At around $20 for a 4-pack ($5 per plug), it's a no-brainer for anyone who needs basic smart switching without energy monitoring.

What impressed us: For $5 per plug, the reliability is remarkable. We tested eight Meross plugs across two homes for four months, and only one needed a WiFi reconnection during that period. The Matter certification means they work with Alexa, Google Home, and HomeKit out of the box.

Pros:

• Cheapest Matter-certified plugs available
• 4-pack pricing under $5 per plug
• Works with all major ecosystems via Matter
• Physical button on each plug
• Compact design
• Meross app works but isn't required (can use native ecosystem apps)

Cons:

• No energy monitoring
• Build quality feels cheap (they work, but don't feel premium)
• 2.4GHz WiFi only
• Meross app is functional but dated
• Occasional slow response (1-2 second delay)
• WiFi reconnection sometimes required after power outages

Bottom line: The best option for deploying lots of smart plugs cheaply. Perfect for seasonal decorations, multi-room lamp control, or converting basic appliances to smart scheduling.

5. Kasa Smart WiFi Outdoor Plug (EP40A) — Best for Outdoors

Check price on Amazon →

Indoor smart plugs can't handle rain, snow, or temperature extremes. The Kasa EP40A is IP64 weatherproof with two independently controlled outlets, making it perfect for outdoor lighting, fountain pumps, holiday decorations, and security lights.

What impressed us: The two independently controllable outlets mean you can put your porch lights on a sunset-to-11pm schedule while keeping your security light on all night — from a single plug. The weatherproof housing survived a New England winter and a Florida summer in our testing without issues.

Pros:

• IP64 weatherproof (rain, snow, heat)
• Two independently controlled outlets
• Matter certified
• Energy monitoring on each outlet
• Individual schedules per outlet
• Kasa app with sunrise/sunset automation
• Heavy-duty build quality

Cons:

• Bulky (designed for outdoor outlets, not indoor)
• More expensive than indoor plugs
• 2.4GHz WiFi range may not reach distant outdoor outlets
• Only works with grounded (3-prong) outdoor outlets
• WiFi signal can be weak at property edges

Bottom line: The only outdoor smart plug you need. The dual independently-controlled outlets with sunset/sunrise scheduling handle 90% of outdoor automation needs. Also great for our best smart home starter kits recommendations.

Buying Guide: Smart Plug Essentials

Matter: Why It Matters (Pun Intended)

Matter is the universal smart home standard. A Matter-certified smart plug works with:

• Amazon Alexa
• Google Home
• Apple HomeKit
• Samsung SmartThings

Why this matters: If you switch ecosystems later (iPhone to Android, Alexa to Google), your Matter plugs still work. Non-Matter plugs (like the Amazon Smart Plug) are locked to one ecosystem.

Our advice: Buy Matter-certified plugs unless you have a specific reason not to.

Energy Monitoring: Surprisingly Useful

Smart plugs with energy monitoring tell you exactly how much power a device uses. This is genuinely useful for:

• Finding phantom power drains (devices that draw power while "off")
• Monitoring space heater usage
• Tracking appliance efficiency
• Calculating the actual cost of running specific devices

If you're energy-conscious, pay the small premium for energy monitoring.

WiFi vs. Thread vs. Zigbee

• WiFi: Most common. Works with your existing router. Can congest your network with many devices.
• Thread: Newer mesh protocol. Faster, more reliable, lower power. Requires a Thread border router (HomePod Mini, Echo Hub).
• Zigbee: Older mesh protocol. Reliable but requires a Zigbee hub (Echo Hub, SmartThings).

For most people, WiFi smart plugs are the simplest option. Thread is better if you have the infrastructure.

Common Mistakes When Buying Smart Plugs

1. Buying plugs that block the second outlet. Some smart plugs are so bulky they cover both outlets. Always check the dimensions and look for "doesn't block adjacent outlet" in reviews.

2. Not checking amperage ratings. Most smart plugs support 15 amps (1,800 watts). Don't use them with space heaters that draw close to 1,500 watts — the margin is too thin. Never use smart plugs with high-draw appliances (dryers, ovens).

3. Forgetting about 2.4GHz WiFi. Nearly all smart plugs require 2.4GHz WiFi, not 5GHz. If your router has a combined network, it usually works fine. If they're separate, make sure you connect the plug to the 2.4GHz band.

4. Using indoor plugs outdoors. Indoor smart plugs will fail when exposed to moisture. Use weatherproof-rated outdoor plugs for any exterior application.

5. Not setting up automations. The real value of smart plugs isn't voice control — it's automation. Set schedules, sunrise/sunset triggers, and away-mode randomization. A smart plug without automations is just a regular plug with extra steps.

6. Ignoring the physical button. When your WiFi goes down, a smart plug without a physical button becomes a dumb plug you can't control. Choose plugs with a manual override button.

The Verdict

The TP-Link Kasa EP25P4 is the best smart plug for most people — Matter certified, energy monitoring included, and rock-solid reliable. The Meross MSS110 is the best budget option for deploying lots of plugs cheaply. And the Eve Energy is the premium choice for privacy-focused Apple users.

Smart plugs are one of the cheapest, most practical smart home upgrades you can make. Start with a 4-pack, automate your most-used lamps and appliances, and you'll wonder why you waited so long.
