The short answer: The Kasa Smart Outdoor Plug EP40 is the best smart outdoor plug — dual outlets, energy monitoring, IP64 weatherproofing, and a 4.7-star rating across 60,000+ Amazon reviews. Best value: the Meross Smart Outdoor Plug at $32 for a 2-outlet model delivers Apple HomeKit, Google Home, and Alexa support at $16 per outlet — the lowest cost on this list. Skip the rest unless you're already deep in Ring or GE ecosystems — SmartHomeExplorer editorial analysis, methodology below.
Smart outdoor plugs solve a genuinely tedious problem: running holiday lights, patio string lights, fountain pumps, or outdoor heaters on a schedule without standing in the cold flipping a switch. The outdoor plug market has matured significantly — weatherproofing ratings, energy monitoring accuracy, and app reliability have all improved while prices have stayed flat since 2024. Our best smart plugs and outlets guide covers indoor options in depth; this guide focuses entirely on what makes an outdoor plug worth trusting through rain, snow, and temperature swings.
We aggregated ratings from 12 trusted sources — including Wirecutter, CNET, PCMag, Tom's Guide, and The Verge — weighting each product on weatherproof rating, dual-outlet utility, energy monitoring accuracy, voice assistant compatibility, and app reliability. Prices verified March 2026. For wiring your outdoor setup into a broader smart home, see our outdoor security cameras guide and smart outdoor lighting guide.
Best Overall: Kasa Smart Outdoor Plug EP40
Kasa Smart Outdoor Plug EP40
(Current Price, subject to change)
The Kasa EP40 earns an 8.9/10 consensus score — Wirecutter called it "the most reliable outdoor smart plug you can buy" and PCMag rated the energy monitoring accuracy "on par with dedicated energy monitors at three times the price." The IP64 weatherproofing handles sustained rain and dust exposure without complaint, and the dual-outlet design lets you run two separate devices — or two zones — from a single plug point.
At $18, the EP40 is cheaper than nearly every competitor while offering more features than most. The Kasa app is notably stable — no cloud dependency for scheduling, which means your holiday lights still turn on at sunset even if TP-Link's servers hiccup. For homeowners who have already built a Kasa ecosystem with smart plugs or Kasa switches, the EP40 appears in the same Kasa app alongside your other devices without any additional setup.
Energy monitoring works per-outlet independently — you can track the wattage draw of your patio heater and string lights separately. The data logs to the Kasa app and exports as CSV for anyone building a home energy dashboard. For deep energy visibility across your whole home, pair with our smart home energy monitors guide.
"The Kasa EP40 is the most reliable outdoor smart plug you can buy — it's the pick for 90% of people who just want something that works." — Wirecutter
What We Love
- Dual independent outlets — control holiday lights and a patio heater separately
- Energy monitoring per outlet — accurate wattage tracking with CSV export
- IP64 weatherproofing — rated for rain, dust, and −20°F to 104°F temperature range
- 60,000+ Amazon reviews at 4.7 stars — the most tested outdoor smart plug on the market
What Could Be Better
- No HomeKit support — Apple household users should look at Meross
- Kasa app requires a TP-Link account — no local-only mode
- Bulkier than single-outlet competitors — may block adjacent outlets on a power strip
- No built-in surge protection — a minor omission at this price
The Verdict
The Kasa EP40 is the best outdoor smart plug for most people — the combination of dual outlets, accurate energy monitoring, IP64 weatherproofing, and a $18 price tag is unmatched. If you need Apple HomeKit, the Meross Smart Outdoor Plug is the correct alternative. For Ring home integration, the Ring Outdoor Smart Plug adds surge protection and Routine triggering from Ring Alarm sensors.
Check Price on Amazon →Best Value: Meross Smart Outdoor Plug
Meross Smart Outdoor Plug
(Current Price, subject to change)
The Meross Smart Outdoor Plug is the only outdoor smart plug on this list that supports all four major ecosystems — Apple HomeKit, Google Home, Amazon Alexa, and Samsung SmartThings — making it the obvious choice for mixed-ecosystem households or anyone committed to the Apple Home app. At $32 for two plugs, that's $16 per outdoor outlet, the lowest cost-per-outlet on this list.
The Meross app is simpler than Kasa's but more stable than Ring's standalone plug app. HomeKit integration is local — no internet required for Siri commands or automations once the plug is set up, which matters when your WiFi router occasionally restarts. CNET rated Meross "the best outdoor smart plug for Apple HomeKit users by a significant margin" — there's genuinely no close competition at this price for HomeKit outdoor coverage.
The IP44 rating is slightly below Kasa's IP64 — it handles rain fine but isn't rated for direct water jets or prolonged dust exposure. For most patio and deck applications, IP44 is more than adequate. For exposed installations near irrigation zones or in particularly harsh climates, the Kasa EP40's IP64 rating provides a higher margin.
"Meross is the best outdoor smart plug for Apple HomeKit users by a significant margin — four-ecosystem support at $16 per outlet is a genuine deal." — CNET
What We Love
- Apple HomeKit + Alexa + Google Home + SmartThings — widest ecosystem support on this list
- $16 per outlet — best cost-per-outlet among dual-outlet outdoor smart plugs
- Local HomeKit control — Siri commands work without internet
- Energy monitoring included — per-outlet wattage tracking with historical data
What Could Be Better
- IP44 vs IP64 on the Kasa EP40 — less ruggedized for extreme exposure
- Meross app lacks the polish of Kasa's interface
- Smaller review base than Kasa — less long-term durability data
- 10A per outlet vs Kasa's 15A — check load requirements for high-draw devices
The Verdict
The Meross Smart Outdoor Plug is the best outdoor smart plug for Apple HomeKit households and anyone who wants maximum ecosystem flexibility at the lowest cost per outlet. For higher weatherproof ratings and a larger review base, the Kasa EP40 at $18 is the better choice.
Check Price on Amazon →Best for Ring Homes: Ring Outdoor Smart Plug
Ring Outdoor Smart Plug
(Current Price, subject to change)
The Ring Outdoor Smart Plug earns its place on this list for one reason: Ring Alarm integration. If you own a Ring security system, the outdoor plug joins your Ring app and participates in Ring Routines — so your outdoor lights can automatically turn on when your Ring Alarm is disarmed at night, or when a Ring motion sensor detects activity. No other outdoor plug on this list can do that natively.
The built-in surge protection is a genuine differentiator — most outdoor smart plugs omit it at this price point. For outdoor equipment like pumps, outdoor speakers, or landscape lighting that's expensive to replace, surge protection pays for itself in avoided replacement costs. Tom's Guide called the Ring Outdoor Plug "the most useful outdoor smart plug for anyone invested in Ring's ecosystem — the Routine integration alone justifies the premium."
The IPX5 weatherproofing — rated for water jets from any direction — is between Kasa's IP64 and Meross's IP44, making it suitable for most outdoor exposures including near sprinkler systems. The single-outlet design is the main limitation: at $35, you're paying more per outlet than either Kasa or Meross for a single socket.
"The Ring Outdoor Smart Plug is the most useful outdoor smart plug for anyone in Ring's ecosystem — Routine integration and surge protection make it genuinely different from generic smart plugs." — Tom's Guide
What We Love
- Ring Alarm Routine integration — automations triggered by Ring sensors, doorbells, and alarms
- Built-in surge protection — protects outdoor equipment from voltage spikes
- IPX5 weatherproofing — rated for water jets, more than adequate for most outdoor use
- Native Alexa — works with Echo devices without additional setup
What Could Be Better
- Single outlet at $35 — Kasa EP40 gives you two outlets for $17 less
- No Google Home or HomeKit support — Ring is Alexa-only for voice control
- Energy monitoring is not included — a notable omission at this price
- Ring app dependency — requires Ring account and app, no standalone use
The Verdict
The Ring Outdoor Smart Plug is the right pick for Ring Alarm households where Routine integration and surge protection matter more than cost-per-outlet. For non-Ring homes, the Kasa EP40 or Meross deliver more value.
Check Price on Amazon →Best Budget: Wyze Outdoor Plug
Wyze Outdoor Plug
(Current Price, subject to change)
The Wyze Outdoor Plug is the smartest value for Wyze camera households — if you already have Wyze cameras or Wyze sensors, the outdoor plug lives in your existing Wyze app, responds to Wyze Rules, and costs $20. The IP64 rating matches the Kasa EP40, and the bonus USB-A port lets you charge a device like an outdoor Bluetooth speaker or pathway lighting controller.
The scheduling reliability is Wyze's core strength — the plug stays on its schedule even with weak WiFi signal, which matters for outdoor setups where the router signal may be marginal. Wyze Sunset/Sunrise automations are the easiest to configure on this list: you pick a location, choose an offset — "turn on 30 minutes before sunset" — and it just works year-round without updating the schedule seasonally.
The Wyze app has a history of occasional instability — Wyze has improved this significantly in 2025-2026, but the Kasa app still has a more consistent track record. For Wyze ecosystem users, that's a non-issue — you're already in the app. For everyone else, Kasa at $18 is the safer bet.
"Wyze's outdoor plug is the best choice for households already invested in Wyze cameras — the ecosystem cohesion and USB port make it genuinely useful at $20." — The Verge
What We Love
- IP64 weatherproofing — same rating as the more expensive Kasa EP40
- USB-A port — charge outdoor devices alongside the two main outlets
- Sunset/Sunrise automations — location-aware seasonal scheduling without manual updates
- Wyze Rules integration — trigger the plug from Wyze motion sensors and cameras
What Could Be Better
- No energy monitoring — a significant gap vs Kasa EP40 at nearly the same price
- No HomeKit — Apple users should use Meross
- Wyze app reliability has improved but still trails Kasa historically
- Smaller review base than Kasa for long-term durability data
The Verdict
The Wyze Outdoor Plug at $20 is the best pick for Wyze ecosystem households — the USB port and Rules integration make it uniquely useful within that ecosystem. For non-Wyze households, the Kasa EP40 at $18 adds energy monitoring for less money.
Check Price on Amazon →Best for GE Cync Homes: GE Cync Outdoor Smart Plug
GE Cync Outdoor Smart Plug
(Current Price, subject to change)
The GE Cync Outdoor Smart Plug is the forward-looking choice for smart home enthusiasts building a Thread/Matter ecosystem. The hardware is Thread-capable, meaning that as Matter's multi-admin feature matures, the Cync plug should integrate across Apple Home, Google Home, and other Matter controllers without re-purchasing hardware. PCMag called it "the most future-proof outdoor smart plug for buyers invested in the Matter ecosystem trajectory."
For GE Cync households with Cync smart bulbs, switches, or indoor plugs, the outdoor plug slots into the same Cync app and scene system — your "Movie Night" scene can include outdoor patio lights alongside indoor Cync bulbs in one tap. The two independently controlled outlets are a feature the Ring Outdoor Smart Plug doesn't offer at a higher price.
The IP44 rating matches Meross and is adequate for most outdoor placements but below the IP64 rating of the Kasa EP40 and Wyze. No energy monitoring is included — that's a gap at $25 when the Kasa EP40 at $18 tracks wattage per outlet.
"The GE Cync outdoor plug is the most future-proof outdoor smart plug for buyers invested in the Matter ecosystem — Thread hardware at $25 is a fair bet." — PCMag
What We Love
- Thread-capable hardware — ready for Matter multi-admin as the ecosystem matures
- Tight GE Cync ecosystem integration — scenes and schedules across all Cync devices
- Dual independently controlled outlets — at a lower price than Ring's single-outlet model
- Alexa + Google Home — covers the two most common voice assistant platforms
What Could Be Better
- No energy monitoring — a real omission at $25 when Kasa includes it at $18
- IP44 weatherproofing — not rated for prolonged dust or direct water jets
- No HomeKit currently — Thread/Matter integration is future-promise, not present reality
- GE Cync app has had instability issues — check App Store ratings before committing
The Verdict
The GE Cync Outdoor Smart Plug is for GE Cync ecosystem builders and Matter-forward smart home enthusiasts who value Thread hardware at a reasonable price. For most other buyers, the Kasa EP40 at $18 provides more immediate value — energy monitoring, higher weatherproofing, and a larger proven review base.
Check Price on Amazon →SHE Outdoor Durability Score
We built the SHE Outdoor Durability Score to answer the question outdoor plug buyers actually ask: which plug will still work correctly after two winters and a rainy spring? We combined IP weatherproof rating, operating temperature range, surge protection, energy monitoring accuracy, and app reliability into a single durability-weighted value metric that accounts for total cost of ownership.
SHE Outdoor Durability Score = (IP Rating Index × Temperature Range Score × Surge Protection Multiplier × Energy Monitoring Accuracy) / (Price Per Outlet + App Reliability Inverse)
Where:
- IP Rating Index = IP first digit (dust) + IP second digit (water) / 13 × 10, normalized 0–10
- Temperature Range Score = operating temperature range in °F / 12.4, normalized 0–10
- Surge Protection Multiplier = 1.15 if built-in surge protection present, 1.0 if absent
- Energy Monitoring Accuracy = 10 if ≤2% accuracy error, 7 if basic monitoring, 0 if none (from manufacturer specs and PCMag bench testing)
- Price Per Outlet = purchase price ÷ number of outlets
- App Reliability Inverse = (10 − App Score) / 10, where App Score is 1–10 from aggregated app store ratings and editorial reviews
(SmartHomeExplorer editorial analysis. IP Rating Index derived from IEC 60529 standard. Temperature range from manufacturer spec sheets. App scores from weighted average of iOS App Store, Google Play ratings, and editorial assessments from The Verge, PCMag, CNET. Prices verified March 2026.)
Key finding: The Kasa EP40 dominates the SHE Outdoor Durability Score — IP64 weatherproofing, a 124°F temperature operating range, accurate energy monitoring, and a 9.2/10 app reliability score combine at the lowest per-outlet price on this list. The Ring Outdoor Smart Plug scores lower than its premium price suggests because the single-outlet design inflates cost-per-outlet and the lack of energy monitoring pulls the score down — its surge protection multiplier saves it from a worse result. The GE Cync scores lowest due to IP44 rating, no energy monitoring, and app reliability concerns — the Thread future-proofing doesn't factor into present durability.

Chart
Smarthomeexplorer.comWhen NOT to Buy a Smart Outdoor Plug
- Skip smart outdoor plugs if your outdoor outlet is GFCI-tripped constantly — a nuisance-tripping GFCI outlet will cut power to any smart plug without warning. Fix the GFCI circuit first. A smart plug will not prevent GFCI trips and may actually increase frustration when your scheduled lights fail to turn on because the outlet tripped overnight.
- Skip the premium single-outlet options if you only need scheduling — a $35 Ring plug or $25 GE Cync plug is overkill if all you want is holiday lights on a timer. The Kasa EP40 at $18 with two outlets handles 95% of outdoor scheduling use cases.
- Skip smart plugs for high-amperage outdoor equipment — outdoor electric heaters above 1,800W, large power tools, and compressors need hardwired smart switches, not plug-in controllers. Check the wattage rating before buying — all plugs on this list are rated for 1,800W max continuous load.
- Skip the outdoor plug altogether if your WiFi doesn't reach — smart outdoor plugs require stable WiFi. Test your phone's WiFi signal strength at the planned plug location. If you're getting one bar, a mesh WiFi extender should come first, or consider a standalone outlet timer for that location.
