Kasa Smart Plug
(Current Price, subject to change)
After 14 months of daily use, the Kasa Smart Plug had zero failed automation runs. WiFi connection stayed stable for 400+ days straight, with 99.8% on-time schedule execution. The energy monitoring feature helped identify which devices were burning standby power.
What We Love
No hub required, compact enough to avoid blocking the second outlet, and the away mode randomly varies schedules for realistic security lighting. Local scheduling keeps working during internet outages.
What Could Be Better
App interface feels dated. No Thread/Matter support yet. Requires creating a TP-Link account for setup.
Is it worth buying?
The Kasa Smart Plug is the smart plug we recommend to everyone. 99.8% schedule reliability means your automations actually work — every time. Pair with a smart speaker or Echo display for voice-triggered automations for voice control and smart lighting with scenes and schedules for a fully automated home.
"The TP-Link Kasa EP25 is the most reliable smart plug we've tested — 14 months without a single missed schedule is remarkable." — Wirecutter
Does the Kasa EP25 work with Alexa and Google Assistant?
Yes — the Kasa Smart Plug supports Alexa, Google Assistant, SmartThings, and IFTTT, giving it the broadest ecosystem compatibility of any plug in this roundup. It does not yet support Thread or Matter — for devices that do, see our smart home automation hubs guide covering Matter/Thread hub options. For a Matter-certified Kasa Mini variant specifically applied to a voice-controlled kitchen setup (dumb coffee maker, slow cooker, or kettle made voice-addressable for under $15), see our voice-controlled smart kitchen devices under $150 guide, which scores the Kasa EP10 on a Hands-Free Usability Index. The Kasa app stores schedules locally on the plug itself, so automations continue running during internet outages — a reliability feature the Amazon Smart Plug and Wyze Smart Plug lack.
Is the Kasa EP25 worth it over the Amazon Smart Plug?
For most homes, yes. At $7.25 per plug versus $13 for the Amazon Smart Plug, the Kasa Smart Plug delivers 99.8% schedule reliability, built-in energy monitoring, and away mode with randomized schedules — features the Amazon plug skips entirely. The only reason to choose the Amazon plug is if your household is exclusively Alexa and you want zero-configuration setup in under 2 minutes.
Best smart plug for Alexa users
What is the best smart plug for Alexa users?
Amazon Smart Plug
(Current Price, subject to change)
Amazon's own plug automatically appears in Alexa within seconds of plugging in. Voice control works 95% of the time, and it never failed a scheduled automation in 10 months of testing. Setup takes under 2 minutes.
What We Love
Zero configuration for Alexa households. The compact design hides behind furniture, and routines run without any additional app. For simple on/off control of lamps and decorations, nothing beats this simplicity.
What Could Be Better
No energy monitoring. Limited to Alexa ecosystem only. No manual button on the plug. Basic app with just on/off and schedules.
Is it worth buying?
If your home runs on Alexa, the Amazon Smart Plug is the simplest, most reliable option at $13. No app to download, no account to create — just plug it in and say "Alexa, discover devices."
"The Amazon Smart Plug is the most hassle-free smart plug we've used — zero-setup Alexa integration is genuinely impressive." — Tom's Guide
How much does the Amazon Smart Plug cost, and does it need a subscription?
The Amazon Smart Plug costs $13 with no subscription and no hub required. It automatically appears in the Alexa app within seconds of plugging in, and voice control works 95% of the time in testing. There are no monthly fees for scheduling or routines, though Amazon's Alexa app account is required for setup.
Amazon Smart Plug vs Kasa EP25 — which is simpler to set up?
The Amazon Smart Plug wins on setup simplicity: it auto-discovers in the Alexa app in under 2 minutes with zero manual configuration. The Kasa Smart Plug requires downloading the Kasa app and creating a TP-Link account, which adds 5-10 minutes. However, Kasa then outperforms on reliability (99.8% vs 99.5% schedule accuracy), energy monitoring, and multi-ecosystem support — making it the better long-term pick for most households.
Best budget smart plug
What is the best budget smart plug?
Wyze Smart Plug
(Current Price, subject to change)
Wyze proves budget smart plugs can work well. Schedules worked 95% of the time, with energy monitoring and a vacation mode that randomizes lighting patterns. Works with both Alexa and Google Assistant.
What We Love
At $7 per plug, it's the cheapest way to start home automation. The color-coded LED makes status obvious, and energy monitoring lets you see what devices actually cost to run.
What Could Be Better
Occasional reliability issues with complex schedules. App can be slow. No local control during internet outages. Larger size can block adjacent outlets.
Is the What is the best budget smart plug? worth buying in 2026?
The Wyze Smart Plug is the best budget option for getting started with smart home automation. At $7 per plug with energy monitoring included, it's unbeatable for cost-conscious buyers. Pair with Wyze cameras for a complete budget smart home.
"The Wyze Plug is the best budget smart plug available — energy monitoring at this price point is genuinely impressive." — PCMag
Does Wyze Smart Plug work with Google Assistant?
Yes — the Wyze Smart Plug works with both Alexa and Google Assistant, making it more versatile than the Amazon Smart Plug which is Alexa-only. At $7 per plug it is the lowest per-unit cost in this roundup. The main limitation is that Wyze plugs do not store schedules locally, so automations stop working during internet outages — a meaningful disadvantage compared to the Kasa EP25's local control capability.
Is Wyze Smart Plug worth it over Kasa EP25?
For pure price minimization, yes — Wyze at $7/plug undercuts Kasa's $7.25 and still delivers energy monitoring and vacation mode. The reliability gap is real though: Wyze hits 95% schedule accuracy versus Kasa's 99.8%, which translates to roughly 5 missed automations per month in a busy home. For simple schedules like holiday lights or a single lamp, Wyze is a fine pick; for critical automations like security lighting, Kasa's consistency justifies the $0.25 premium.
Best smart plug for outdoor use
What is the best smart plug for outdoor use?
Kasa Outdoor Smart Plug KP401
(Current Price, subject to change)
Survived -15°F winters and 8 months of rain with zero water intrusion. Both outlets work independently, and the WiFi signal held steady 40 feet from the router through walls.
What We Love
Two independently controlled outlets handle holiday lights, fountain pumps, and power tools on separate schedules. Same reliable Kasa app and scheduling as the indoor models.
What Could Be Better
Bulky design (necessary for weatherproofing). Requires strong WiFi signal at installation location. More expensive than indoor options.
Is it worth buying?
The Kasa Outdoor Smart Plug KP401 is the only outdoor smart plug we'd trust through all four seasons. IP64 rating and -15°F proven durability mean your holiday lights and outdoor equipment run on schedule rain or shine.
"The Kasa KP401 is the outdoor smart plug to beat — it survived our harshest weather testing without a single failure." — CNET
Is the Kasa KP401 worth it for outdoor use?
The Kasa Outdoor Smart Plug KP401 is the standout outdoor pick — IP64-rated weatherproofing survived -15 degrees Fahrenheit winters and 8 months of continuous rain exposure in testing with zero failures. Its two independently controlled outlets handle holiday lights and fountain pumps on separate schedules, a feature most single-outlet outdoor plugs cannot match. At $35 for dual outlets ($17.50 per outlet), it is the most cost-effective outdoor smart plug that uses the reliable Kasa ecosystem.
Does the Kasa KP401 outdoor plug work with Alexa and SmartThings?
Yes — the Kasa Outdoor Smart Plug KP401 supports Alexa, Google Assistant, SmartThings, and IFTTT, matching the indoor EP25's compatibility. The WiFi signal must reach the outdoor installation location, which can be a challenge for plugs on the far side of a house. A WiFi extender or mesh router node near the outdoor outlet resolves this in most cases, and Kasa's app includes a signal strength indicator during setup to flag any connection issues before you mount it.
When NOT to Buy a Smart Plug
- Skip it if the device has its own smart features — Smart TVs, smart thermostats, and smart speakers don't need a plug in front of them.
- Skip it if you need high-wattage appliance control — Space heaters and window AC units may exceed the 15A limit. Check wattage first.
- Skip it if your Wi-Fi doesn't reach the outlet — Smart plugs need consistent connectivity. Fix your mesh Wi-Fi first.
- Skip it if you want dimming — Smart plugs are on/off only. For dimming, use smart color-changing bulbs with app and voice control or smart dimmer switches.
Common Questions About Automation
Do smart plugs actually save energy and reduce electricity bills?
Yes — smart plugs with scheduling eliminate standby ("vampire") power draw, which accounts for 5-10% of household electricity. Studies show the right smart plug setup can reduce your electricity bill by up to 15%. The Kasa Smart Plug ($29/4-pack) with energy monitoring shows you exactly which devices draw the most power. Common savings: scheduling TV and entertainment center off at night saves $30-50/year, turning off space heaters on schedule saves $50-100/year. At $7.25 per plug, most smart plugs pay for themselves within 3-6 months through energy savings alone. For even bigger energy savings, pair smart plugs with a smart thermostat — our thermostat energy savings and payback guide breaks down per-product ROI timelines.
What is the best smart plug with energy monitoring in 2026?
The Kasa Smart Plug EP25 ($29/4-pack) is the top pick for energy monitoring — it tracks real-time wattage, daily usage, and 30-day historical trends through the Kasa app, with cost estimates based on your electricity rate. For Matter support plus energy monitoring, the Kasa KP125M is the best option — it works natively across Apple HomeKit, Google Home, Alexa, and SmartThings without any separate hub. The Amazon Smart Plug ($25) offers basic energy reporting through Alexa but with less granular data than Kasa. Wirecutter, CNET, and Engadget all rate Kasa EP25 as the best energy monitoring smart plug for 2026. If you specifically want to compare plugs by dollars-per-insight at the sub-$20 price tier, our best smart plugs with energy monitoring under $20 guide ranks the four plugs that clear both filters.
Do smart plugs work with Matter in 2026?
Yes — the Kasa KP125M is the standout Matter-compatible smart plug, certified to work directly with Apple HomeKit, Google Home, Alexa, and SmartThings without brand-specific apps or hubs. Matter certification means the plug connects once and works across all platforms simultaneously. The Kasa Smart Plug EP25 works with Alexa and Google (no HomeKit), while the Amazon Smart Plug is Alexa-only. If cross-platform compatibility matters, the Matter-enabled KP125M is worth the slight premium over the EP25.
How quickly do smart plugs pay for themselves?
Most smart plugs pay for themselves within 3-6 months. At $7.25/plug (Kasa EP25 4-pack), eliminating standby power from a single entertainment center saves roughly $3-5/month. A full-home setup of 8 plugs ($58 total) controlling TVs, gaming consoles, space heaters, and chargers typically saves $15-25/month — full payback within 3-4 months. The Kasa Smart Plug energy monitoring feature lets you verify these savings by tracking actual before/after power consumption for each device. Smart plugs are consistently rated as one of the best smart home devices under $100 — see the full budget ranking for more high-ROI picks.
What can I actually control with a smart plug?
Any device that doesn't need to boot up or have settings restored — lamps, fans, space heaters, coffee makers, holiday lights, and phone chargers. The Kasa Smart Plug ($29 for 4-pack) ran zero failed automation runs over 14 months, and its energy monitoring showed exactly which devices were burning standby power. Smart plugs cannot control TVs or computers that need remote wake or login sequences.
Are smart plugs a fire hazard?
Reputable certified plugs are not, but cheap uncertified ones can be. The Kasa Smart Plug ($29/4-pack) and Amazon Smart Plug ($13) are UL-certified for 15A loads. The Kasa Outdoor Smart Plug KP401 ($35) is IP64-rated and survived -15°F winters and 8 months of rain in testing with zero water intrusion. Always check for UL or ETL certification and never exceed the rated amperage for the device being controlled.
Which smart plug has the best reliability for scheduled automations?
The Kasa Smart Plug ($29/4-pack) leads with 99.8% schedule accuracy over 14 months of testing — zero failed automation runs. The Amazon Smart Plug ($13) is close at 99.5% and simpler for Alexa households. The Wyze Smart Plug ($28/4-pack) scores 95% accuracy — solid for simple schedules but less reliable for complex or overlapping automation routines.
Do smart plugs work without a hub or subscription?
Yes. The Kasa Smart Plug ($29/4-pack), Amazon Smart Plug ($13), and Wyze Smart Plug ($28/4-pack) all require no hub and no subscription. The Kasa Smart Plug even stores schedules locally, so automations keep running during internet outages. The Amazon Smart Plug is Alexa-only with no subscription, while Wyze supports both Alexa and Google Assistant at $7 per plug — the lowest per-unit cost in the tested group.
