Every December I set the eaves lights at dusk, forget them until midnight, and then walk out in gloves at 1am to flip the switch. After doing that three seasons in a row, I bought a smart plug. The lights now come on at sunset by themselves and go off at a set time, and I have not touched a switch since.
That is the whole promise behind the best smart plugs for holiday lights: no walking to a dark switch, no timer dial to reset, and one app that turns the tree, the eaves and the yard on a single tap. The catch is that most of the wrong plug for the job is either not sealed for rain or will not reach your Wi-Fi at the far end of the house.
We compared eight plugs built for light runs, weighing IP weather ratings, amps, Wi-Fi band, ecosystem support, footprint and setup friction. The Kasa Outdoor Smart Plug EP40 came out on top for most homes. Below, each pick gets a plain verdict, a look at who it suits, and who should pass..

How We Chose
We built this list around the way holiday lights actually get wired, not around brands. Every pick was assessed on four things: whether it is sealed for the exposure it will face, how much current it will carry, which ecosystems it answers to, and how much wall space it takes up.
Current matters more than most guides admit. A single 15A outlet is a 1,800 to 1,875 watt ceiling, and several medium LED strands can get close to half of that. We also weighted setup, because a plug that needs three pairing attempts at 4pm on a cold Saturday has already failed the test.
Where a rating is manufacturer-stated rather than independently tested, we say so. Rating and review counts come from the retail listing at the time of writing, and they move over time.
1. Kasa Outdoor Smart Plug EP40 – Best Overall for Holiday Lights
Kasa Outdoor Smart Plug, Smart Home Wi-Fi Outlet with 2 Sockets, EP40
15A/1875W per outlet,IP64 with attached cover,6-inch cord,ETL certified
Pros
- Two outlets controlled independently so you can run eaves and yard at different times
- IP64 seal with a hinged waterproof cover
- Up to 300 ft Wi-Fi range in open space
- Works with Alexa and Google Home with no hub
- 2-year warranty
Cons
- 2.4GHz only so it will not join a 5GHz network
- 6-inch cord means the receptacle has to be in reach
- Matter support not listed for this model
This is the plug I keep in my own eaves outlet. It carries two independently controlled outlets at 15A each, which is the single feature that matters most when you are wiring a house: the roofline run and the garden uplights can run on different schedules from the same wall receptacle.
The 6-inch cord and hinged cover are less glamorous than they sound. The cord means you can mount the plug body just below the receptacle so the sockets face down, which sheds water and ice instead of letting it sit in the openings. That is exactly what you want when the outlet is on a north-facing wall for three months.
While you are testing circuits in November, it is also worth stocking the kitchen. Our Xmas cookie recipes are easy to batch once and leave out of the way.
Owners consistently point to three things: the two outlets really are independent, the schedules hold week after week, and the Wi-Fi reaches further than competing units. It is also the best-supported pick of the group for voice control, with both Alexa and Google Home working without a hub.
The honest weakness is ecosystem reach. This is a Wi-Fi-only unit with no Matter certification listed, so if your household later standardises on Matter, you will replace it sooner than you would a Matter model. Sunrise and sunset offset is built in, so you set it once and it tracks the shortening December days for you.
What you should check before buying the EP40
Measure the distance from your router to the outlet. The 300 ft figure is open space, and it means open space. Through a brick exterior wall, a second storey and a closed door, expect materially less, and have a mesh node plan in reserve.
Check your strand wattage. A single outlet is capped at 1,875W, so do not plan to hang a whole roofline off one socket. The second independent outlet buys you flexibility, not extra capacity.
Who should skip the Kasa EP40
Skip it if your lights live in an Apple Home home and you want everything to live in one app with Siri answering. Meross covers that case natively. Skip it too if you want to see live wattage and running cost from the app, because the EP40 does not report energy.
2. Tapo Matter Outdoor Smart Plug P400M – Best for Matter and Apple Home
Tapo Matter Outdoor Smart Plug, 2 Individual Outlets, P400M
Matter compatible,IP65 sealing,-4F to 122F range,2 outlets at 1800W
Pros
- Matter support covers Apple Home/Alexa
- Google Home and SmartThings
- IP65 sealing rated for -4F to 122F
- Mounting screw and stabilising post resist cable strain
- Up to 300 ft open-field reach with dual antennas
- Two independent 15A outlets
Cons
- Smallest review base in the group at just over 1000 ratings
- 2.4GHz hardware so range is still limited versus mesh
This is the pick for anyone who does not want to bet on one assistant. Matter support means the same plug shows up in Apple Home, Alexa, Google Home and SmartThings, so a mixed-ecosystem household can use one device instead of four. It is the only unit in this roundup with that flexibility.
The physical design is the other story. At 1.22 by 1.22 by 0.61 inches it is a small block, and it comes with a mounting screw and a stabilising post. Plugging a heavy light adapter into a small body in cold weather is exactly when you want the housing held rigid.
On paper the radio is the strongest here, with a stated 300 ft in open field and 164 ft through three concrete walls. That is manufacturer-stated, so treat it as a target rather than a promise, but dual antennas are a real advantage for a plug mounted at the back of the house.
It carries 15A at 1,800W across two independent outlets, and the Tapo app covers schedules, timers, ambiences and device grouping. The IP65 seal and a -4F to 122F operating range handle the winter end of the scale without argument.
When the P400M is the right call
Choose it if more than one assistant answers in your home, or if you expect to switch platforms in the next few years. Matter is the reason to pay a little more now rather than replace an entire outdoor setup later.
Also choose it for reach. If the outlet is more than a straight line from your router, the dual antennas are the safer bet in this group.
Where it falls short
It is a newer release, and roughly a thousand ratings is thin evidence next to the Kasa. If you want a deep body of long-term owner reports before committing a whole exterior run, the EP40 has more of them. The 2.4GHz ceiling on range still applies no matter how good the antennas are.
3. Amazon Basics Outdoor Smart Plug – Best for Alexa-Only Homes
Amazon Basics Outdoor Smart Plug with 2 Individually Controlled Outlets, Works with Alexa Only, Voice Control, Weather Resistant, 2.4 GHz Wi-Fi, No Hub Required, Black
IP65 water-jet resistant,Two independent outlets,UL rated at 15A
Pros
- IP65 enclosure handles water jets
- condensation and spray
- Two outlets controlled independently by voice or app
- Setup runs entirely inside the Alexa app
- Grouping combines several plugs into one routine
- UL rated at 15A
Cons
- Alexa only
- so no Google Home
- Apple Home or SmartThings
- 2.4GHz Wi-Fi only
Nothing about this plug asks you to learn a new app. If Alexa already runs your home, setup happens inside the app you already use, and schedules, routines and grouping all live in the same place. For a first-time smart home owner wiring two strands, that is worth more than a spec sheet line.
The sealing is genuinely strong for the money. IP65 means protection against low-pressure water jets, which is the rating you want on an exposed soffit or a post near a sprinkler head. Two independently controlled outlets means the same independence as the pricier units.
It is UL rated at 15A, which matters more than it sounds. Certification marks on weatherproof plugs are not uniform across brands, and UL is one of the marks that tells you the enclosure was evaluated as an outdoor device rather than a plastic box that happens to have a lid.
A zero-touch linking option ties the plug to your Amazon account at checkout if you buy through the same account, which removes the pairing step entirely. Grouping lets you combine several outdoor plugs so one voice command runs the whole exterior.
What to confirm before you commit
Confirm nobody in your home uses Google Home or Apple Home. This is a one-way door, and a plug that only answers Alexa is unusable in the other ecosystems rather than merely limited.
Confirm your network. A 2.4GHz-only band is standard for smart plugs, so if you have split your SSIDs, the plug goes on the 2.4GHz one.
Who should pass on it
Anyone with a mixed household, or anyone planning to move to a different platform, should look at the Matter-capable Tapo instead. The same applies if the outlet is far from the router, because this is a plain 2.4GHz unit with no extra antenna design to lean on.
4. Meross Outdoor Smart Plug MSS620 – Best for Apple Home and Siri
meross Outdoor Smart Plug Work with HomeKit, Alexa, Google and SmartThings
IP44 housing with socket covers,2 independent outlets,ETL and FCC certified
Pros
- Works with Apple HomeKit/Siri/Alexa
- Google Assistant and SmartThings
- Two independently controlled outlets
- Fire-retardant housing with overload protection
- Mediatek chipset aimed at longer reach and fewer dropouts
Cons
- IP44 is the weakest seal in this roundup
- HomeKit remote access needs a HomePod or Apple TV
If your household runs Apple Home, this is the plug that disappears into the app you already use. It is the broadest compatibility list in the group, covering HomeKit and Siri alongside Alexa, Google Assistant and SmartThings, so a mixed house can still keep one device.
The Mediatek IoT chipset is worth noting because it is specified for longer range and a lower offline rate. That matters more outdoors than any indoor benchmark, since the enclosure walls and the distance from the router both work against you.
At 3.2 ounces it is the lightest unit here, which is a real advantage when you are mounting it high on a soffit or clipping it under an eave. The fire-retardant housing and overload protection are the kind of detail you want on a device that sits outside all winter.
Scheduling, timers and sunrise and sunset settings are all handled in the Meross app, so you can set the outdoor run once and leave it. The 2-year manufacturer warranty matches the class.
What matters about the IP44 rating
IP44 protects against solid objects over 1mm and water splashing from any direction. That covers rain and spray, but not a hose pointed at the outlet or a driving storm from the side. Under a covered soffit or eaves it is the right answer.
If your plug will sit on a bare wall in the open, or within reach of a sprinkler, the IP65 units on this list are a better match.
Who should look elsewhere
Skip it if the outlet is fully exposed to weather rather than under cover, because the IP44 seal is the weakest in the group. Also plan for the Apple Home requirement: remote HomeKit control needs a HomePod or Apple TV acting as the home hub.
5. Wyze Plug Outdoor – Best for Tracking Holiday Energy Use
Wyze Plug Outdoor, Dual Outlets Energy Monitoring, IP64, 2.4GHz WiFi Smart Plug, Works with Alexa, Google Assistant, IFTTT, No Hub Required, Black
Live energy monitoring,IP64 weather rating,Wi-Fi and Bluetooth,15A at 120V
Pros
- Only plug here that reports energy use in real time
- IP64 sealing with Wi-Fi and Bluetooth together
- Works with Alexa
- Google Assistant and IFTTT
- Rubber construction suits damp locations
- ETL certified at 15A on 120V
Cons
- Most expensive plug in this roundup
- IP64 rather than IP65
- 2.4GHz Wi-Fi only
This is the one to buy if you have ever wondered what a season of holiday lights actually costs. It is the only plug in this roundup with built-in energy monitoring, so the app shows live draw on your strands and accumulates the total across the season instead of leaving you to guess.
Beyond that, it behaves like a solid outdoor unit. IP64 sealing, rubber construction that suits damp locations, ETL certification and a 15A rating on 120V. Bluetooth sits alongside Wi-Fi, which makes first-time pairing far less painful when the signal at the outlet is marginal.
The reporting is most useful during setup rather than after. Run each strand for a minute and note the number. That turns the 1,800W ceiling from an abstract limit into a real figure for your own lights, and it is the fastest way to avoid a nuisance trip on a cold December night.
Alexa, Google Assistant and IFTTT are all supported with no hub, so the monitoring is the only unusual feature here. Everything else follows the standard outdoor plug pattern.
When energy monitoring pays off
It pays off if you have inherited a haul of mixed strands and have no idea what they draw. It also pays off in multi-zone homes, where seeing which zone is pulling the most tells you where to cut the schedule or where to split the load.
It matters less if you already know your lights are modern LED strands with a low, predictable draw.
What to weigh against it
This is the most expensive unit we list, and the IP64 seal is a step below the IP65 models. If your outlet is fully exposed rather than under an eave, one of the IP65 units is the better physical match. If you only want monitoring, nothing else here offers it.
6. Geeni Outdoor Duo Wi-Fi Smart Plug – Best for Covering Several Light Zones
Geeni Outdoor Duo Wi-Fi Smart Plug | 2 Weatherproof Outlets, Compatible with Alexa & Google Assistant | Wireless Remote Control & Timer for Holiday Lights, Appliances, and More, 2-Pack
Two-pack giving four outlets,IP65 weatherproof design,2.4GHz Wi-Fi
Pros
- Two weatherproof plugs per box gives four outdoor outlets
- IP65 design for rain
- snow and harsh conditions
- Alexa and Google Assistant voice control
- Schedules and timers in the Geeni app
- Works on any 2.4GHz network with no extra hardware
Cons
- Two-pack only
- no single unit option
- No IP certification standard listed beyond the IP65 claim
Most holiday frustration is a coverage problem, not a product problem. You need a plug at the eaves, one by the patio, one at the garden bed and one near the gate, and buying single units one at a time turns that into four separate errands. This comes as a two-pack, which means four weatherproof outlets out of one box.
Each unit carries two outdoor outlets, so the pair covers a small exterior comfortably. Alexa and Google Assistant both answer, and the Geeni app handles remote control, custom schedules and timers on any 2.4GHz network with no added hardware.
The IP65 weatherproof design is what makes the two-pack practical for the zones an indoor plug cannot touch. Two units at the front and back of the house is often the difference between a tidy install and a power lead running through a doorway.
The housings are moulded polycarbonate in grey, and owners describe setup as straightforward, with scheduling being the feature most used afterwards.
How to use the two-pack well
Give each plug a zone rather than splitting a single zone across both. One unit on the front of the house and one at the back lets you run the exterior as a single routine, and you can still switch the patio off early when guests have gone in.
Pair them one at a time. Multi-unit onboarding is where most setup frustration comes from, and doing the first one fully before starting the second avoids it.
What to be aware of
It is sold as a two-pack, so if you only need one outlet for a covered porch, this is more hardware than the job requires. The listing also states the IP65 claim without naming a certification standard behind it, so treat the figure as manufacturer-stated.
7. GE Cync Outdoor Smart Plug – Best for Bluetooth-Assisted Setup
GE Cync Smart Plug, Outdoor Bluetooth and Wi-Fi Outlet Socket, Weather Resistant Plug, Works with Alexa and Google, Black (1 Pack)
Wi-Fi and Bluetooth,Weatherproof outlet cover,15A rating
Pros
- Bluetooth handles local control while Wi-Fi handles remote access
- No hub required
- pairs in the Cync app
- Weatherproof cover with three-prong plug compatibility
- App scheduling handles dusk activation
- Owners report it holds up outdoors year after year
Cons
- Setup instructions can be unclear and pairing may take retries
- Some owners report Alexa finding only one of the two outlets
The distinguishing feature is dual connectivity. Bluetooth handles local control, so the plug can be set up and operated at the outlet even when the Wi-Fi signal there is poor, and Wi-Fi takes over once it is configured for remote access and voice control.
That makes it a good companion to the multi-pack problem. If you have struggled with plugs that refuse to join from the far end of the house, having a local path to pairing is a genuine advantage rather than a spec-sheet nicety.
The weatherproof outlet cover and three-prong compatibility suit standard exterior receptacles, and the 15A rating sits at the top of the class. It plugs straight in with no cord, which keeps the profile flat against the wall.
Owners mostly like the scheduling, particularly turning lights on at dusk from the app. Alexa and Google Home both work with no hub, and the recurring theme in long-term reports is that it keeps working outdoors year after year.
What to expect during setup
Budget extra patience the first time. The instructions are the weak point, and pairing can take several attempts, especially on an iPhone where you may need Bluetooth permission enabled for the app.
Once it is on the network it behaves normally, and the local Bluetooth path means you can rename and schedule it from the outlet itself if the Wi-Fi is struggling.
Who should consider an alternative
If you rely on Alexa to find both outlets by voice, the recurring reports of only one outlet being discovered make the Kasa or Amazon Basics units the safer choice. For Apple Home or Matter households, this unit is not the right fit.
8. Ring Outdoor Smart Plug – Best for Ring Homes and Harsh Cold
Ring Outdoor Smart Plug
IP66, IP64 in-use,15A total,1875W resistance,-4F to 122F
Pros
- IP66 sealing is the most weather-resistant in this roundup
- Two outlets labelled A and B with a manual toggle on each
- Stated operation from -4F to 122F
- Heavy-duty body with a right-angle power cord
- Scheduling and grouping in the Ring app
Cons
- Smart features need a Ring Bridge
- Ring Alarm Pro
- Echo 4th Gen or Echo Show 10
- No support for triggering lights with Ring motion sensors
- Bulky and hard to conceal
- Lowest rated of the eight at 4.2
The sealing here is the best of the group. IP66 covers dust, water jets and powerful spray, and the stated operating range runs from -4F to 122F, which makes it the safest choice for a northern eaves run or an exposed post in a place where ice accumulates on the housing.
Two independently controlled outlets are labelled A and B, and each has its own manual toggle on the body. That physical button matters more than it sounds: when the lights are already on, you can cut one run without opening the app.
The body is genuinely hefty, with a heavy-duty right-angle cord, and 15A total across both outlets with a 1,875W resistance load. That is the ceiling for the pair, not for each socket, so plan your load for the unit as a whole.
For anyone already running Ring, scheduling and grouping in the Ring app will feel native. That is the entire case for this plug, and it is a narrow but real one.
What the bridge requirement means
Smart features need a Ring Bridge, Ring Alarm Pro, an Echo 4th Gen or an Echo Show 10. Without one of those the plug has no schedule, no app control and no voice control, so count that hardware before deciding.
It also does not respond to Ring motion sensors, so if your plan was to have a camera trigger the lights, this will not do it.
Who should skip it
Skip it unless you already run Ring. Everyone else is paying for ecosystem support they will not use and accepting the lowest rating in this roundup. It is also the hardest plug to hide, which matters if the outlet is visible from the street.
Match a Plug to Every Holiday Light Zone
A typical exterior display splits into four or five zones, and each zone has a different exposure and a different schedule. The tree is a single indoor socket. The eaves are sheltered but wide. The patio gets a heavy duplex strand and the most use. Garden uplighting and the fountain are the parts you actually forget to switch off.
Tree and indoor strands: a compact indoor plug is enough. Keep it away from heat and never coil a cord under a tree skirt that blocks airflow.
Eaves and roofline: sheltered, so IP64 is comfortable. Mount vertically with the sockets facing down and use the clamp and screw the outdoor units ship with.
Patio and deck: full exposure with the heaviest load, so choose IP65 and check the strand draw first. A dual-outlet unit lets you split the run.
Garden uplighting and the fountain: the highest forgetfulness zone. These are also the plugs that earn their keep from March to November, running garden lights and a pond pump long after the decorations come down.
Garage and inflatable decor: a duplex inflatable draws a steady motor load, so confirm the amperage on its label before it shares an outlet with lights.
Before the season, the same outlets can take the patio string lights you use in summer, garden uplights, and the heat mats that clear steps after a snowfall. That is the quiet argument for buying weatherproof hardware rather than indoor plugs you will store away, and it is a better one for the budget than most people expect once the lights come down.
Planning the food side early also makes the season calmer. Our mincemeat recipe ideas and vegan holiday recipe ideas cover the make-ahead side of the same weeks.
What the IP Ratings Mean for Outdoor Holiday Lights
An IP rating has two numbers. The first measures protection against solid objects, and the second measures protection against water. IP44 means splash resistant from any direction. IP64 adds dust-tight sealing. IP65 adds protection against low-pressure water jets. IP67 adds temporary immersion.
IP44: splashing water from any angle. Fine under an eave or in a covered porch. Not for an open wall or a sprinkler head.
IP64: dust-tight plus splash protection. The sensible default for most exterior holiday runs.
IP65: water-jet protection. The right call for anything directly exposed to rain, and for units near a downspout.
IP66: as IP65 with stronger dust protection. Worth it for a northern run where ice and grit build up on the housing.
Mounting still matters after the rating. Vertical orientation with outlets facing down sheds water and ice, and a clamp or screw stops a cable being pulled sideways when you unplug a wet adapter in January.
How Many Smart Plugs Your Holiday Light Run Needs
Count zones, not strands. Two independently controlled outlets on one plug cover most of a single zone, so the answer is usually between two and four plugs for a full exterior display, plus one indoors for the tree. A professional installer in the r/homeautomation community runs seven outdoor plugs, one per zone, and each takes under two minutes to set up.
The mistake is buying eight plugs and not knowing what to do with them, which happens more often than over-buying. The other mistake is buying two and running a lead across a doorway to reach the third zone. Outdoor-rated cable between zones is safer and tidier than a trip hazard across an entrance.
Whatever you choose, set them up one at a time. The most common complaint on smart home forums is a multi-pack where only the first unit connects and the rest never finish pairing, which is almost always fixed by onboarding the first plug fully, then starting the next.
What Never to Plug Into a Smart Plug
Never attach a space heater, hair dryer, air conditioner, kettle or portable heater to any smart plug. These draw close to their limit on their own, and a relay that cycles them adds heat and wear for no benefit.
Stay under the ceiling. A 15A outlet at 120V supports about 1,800 watts, and that is the total for the socket or the unit, not per strand. Older incandescent strands are the usual culprit, since they pull several times what a modern LED strand does.
Avoid anything that needs a physical button press after power returns, and skip medical or safety equipment for the same reason. If an appliance cannot start itself once the relay closes, a scheduled restart simply leaves it dead until someone walks over.
And never use an indoor-rated plug outdoors. Water and mains electricity is the one combination with no workaround.
How to Choose the Right Smart Plug for Your Lights
Start with exposure, then load, then ecosystem, then size. Exposure sets the IP rating. Load sets whether you need one outlet or a duplex. Ecosystem decides whether the plug will still work in five years. Size decides whether it physically fits the weatherproof box on your wall.
Check the IP rating first. IP44 under cover, IP64 for general exterior use, IP65 for anything open to the sky. Matching the rating to the exposure is the cheapest decision in this whole guide.
Count amps honestly. Read the label on your strands, add them up, and stay well under the limit for the socket. If you want to know your real draw, the Wyze reports it live.
Assume 2.4GHz only. Every plug in this roundup is 2.4GHz. If your router splits bands and you do not know the 2.4GHz password, set that up first. It is the most common setup failure and it is entirely avoidable.
Test Wi-Fi at the outlet before you buy. Under 15 metres from the router, most units are fine. Between 15 and 30 metres, and through exterior walls, a mesh node or a dedicated outdoor node is the remedy. Beyond 30 metres, plan on network hardware rather than a better plug.
Use sunset automation, not a clock timer. Through December the sun sets about four minutes earlier each week, so a fixed 5pm schedule drifts visibly. Sunset-based routines stay aligned, and Kasa, Meross and Tapo all support the offset.
Check the recovery behaviour after an outage. Most of these plugs restore their last state when power returns, which is what you want for a display. Confirm that before you rely on a winter storm recovery.
Check whether it fits the box. A bulky plug that will not seat behind a weatherproof cover is unusable no matter how good it is, so measure the box before ordering the Ring or any corded unit.
Once the lights are sorted, it usually helps to have something on for the holidays. Our Christmas cookie recipes for families and holiday food recipe ideas cover the other side of the season.
Frequently Asked Questions
Can a smart plug be used outdoors?
Yes, but only if it is rated for outdoor use. Indoor plugs are not sealed, and water plus mains electricity is a genuine hazard. Look for an IP44 rating minimum under a covered eave, IP64 for a general exterior run, and IP65 for anything directly exposed to rain. Never mount an indoor-rated plug on an outside wall.
Do smart plugs work off Wi-Fi?
They need Wi-Fi to be reached remotely, but they run on 2.4 GHz rather than 5 GHz. Once configured, the schedule is stored on the plug, so lights still switch on at sunset even if the internet connection drops. The real outdoor problem is reach: through exterior walls the connection weakens, and a mesh node fixes it.
What devices should not be used with smart plugs and why?
Avoid space heaters, hair dryers, air conditioners and kettles, because they draw close to the 15A limit on their own and cycling a relay adds heat. Skip anything over 1,800 watts, anything that needs a button press after power returns, and medical or safety equipment. Never use an indoor-rated plug outdoors.
Do smart plugs increase the electricity bill?
Only slightly, and far less than forgetting to switch lights off. A plug draws roughly half a watt on standby, which works out to a few pence a year on a typical utility rate. Scheduling strands off at a set time saves far more than that, and a plug with energy monitoring can show you exactly what your strands draw.
Which brand is considered the best for smart plugs?
TP-Link is the most widely recommended brand across outdoor and indoor smart plugs, with the Kasa Outdoor Smart Plug EP40 as the consensus outdoor pick for its IP64 sealing and independent dual outlets. Brand is still a poor shortcut when ecosystems differ, so check voice assistant support before buying rather than buying on name alone.
How many smart plugs do I need for outdoor Christmas lights?
Count zones rather than strands. A duplex plug covers one zone, so a full exterior display usually needs two to four plugs, plus one indoors for the tree. A professional installer runs seven outdoor plugs, one per zone, and setting them up one at a time prevents the multi-pack pairing failures people report.
The Verdict for 2026
The Kasa Outdoor Smart Plug EP40 is our best smart plug for holiday lights in 2026. Two independently controlled 15A outlets, IP64 sealing, a hinged cover, a 6-inch cord you can mount facing down, and sunset scheduling that follows the shortening December days. It works with Alexa and Google Home with no hub.
Go with the Tapo P400M if Matter matters to you, with the Amazon Basics plug if Alexa is the only assistant you use, with Meross if you live in Apple Home, and with the Wyze if you want to see what your strands actually draw. Whatever you pick, buy outdoor-rated, stay under 1,800 watts, and set up one plug at a time.
