Only weather-rated smart plugs belong outside, and the Kasa Outdoor Smart Plug EP40 is the one most holiday displays end up running on. We spent 2026‘s setup season comparing ten outdoor smart plugs on the four things that actually decide whether a display works: the IP water rating, how many light runs you can switch separately, the 15A load ceiling, and whether the schedule survives an internet outage.
Most of this category is generic black plastic with a weekly timer inside, so the differences are narrow but real. Some switch two outlets independently. Some dim. A few report live wattage so you can see what a display costs. Two carry IP65 shells for spots with no cover overhead, and the rest stop at IP44 or IP64. Once you sort by those four axes, the right pick for a covered porch is obvious, and so is the one for an open garden stake.
One safety note before anything else. An indoor smart plug left outdoors is the single most common mistake in this category, and it is a genuine hazard rather than a warranty question. Buy the outdoor-rated version every time, plug it into a GFCI-protected receptacle, and mount it vertically with the outlets facing down so water runs off instead of pooling. We explain the ratings in full below.
If you are also choosing the lights themselves, our picks for party lights for home parties cover indoor runs, and the guide to outdoor holiday projectors for houses is the better route for anything you project onto a wall or tree line.

Top 3 Picks for Best Outdoor Holiday Lights in 2026
Kasa Outdoor Smart Plug EP40
- Two independently switched outlets
- IP64 weather resistance
- 15A per outlet
- Alexa and Google Home
TREATLIFE Outdoor Dimmer Plug
- Dims string lights to 400W
- IP44 waterproof rating
- Sunrise and sunset scheduling
- Alexa and Google Assistant
Kasa Outdoor Smart Dimmer KP405
- IP64 water resistance
- Dims to 300W incandescent
- 300ft Wi-Fi range
- SmartThings and Alexa
The EP40 takes the top slot because it solves the actual holiday problem: two separate light runs, one schedule each, and a 15A rating on both sockets. The TREATLIFE dimmer is the pick when the string lights are dimmable and you want them to fade rather than snap on. The Kasa KP405 earns its place as the dimmer with a higher IP rating than most of the dimmers in this list.
Can You Use a Smart Plug Outside?
Only a plug rated for outdoor use, mounted on a GFCI-protected receptacle. Indoor smart plugs are not weather-sealed and are not safe in rain or snow. Outdoor models carry an IP code: the second digit tells you how much water they tolerate, and anything from IP44 upward is acceptable for holiday lights.
Here is what the codes mean in practice, and where each one belongs:
IP44 – protected against solid objects over 1mm and splashing water from any direction. Fine under a covered porch, an eave, or a patio roof. Not fine in an open yard.
IP65 – dust-tight and protected against water jets. This is the rating you want for an exposed garden stake or an uncovered receptacle.
IP64 – dust-tight and protected against splashing water from any direction, rated for temporary immersion. The sweet spot for most holiday installations.
IP67 – dust-tight and protected against temporary immersion in water. Overkill for string lights, useful if you also control a fountain.
The first number is always particle protection, so a higher first digit means a better seal around the internals. Owners on the Home Assistant community forums repeat the same rule: an outdoor-rated plug or nothing for a display that lives outside from November through January.

1. Kasa Outdoor Smart Plug EP40: Two Outlets Switched Separately
Kasa Outdoor Smart Plug, Smart Home Wi-Fi Outlet with 2 Sockets, EP40
- Two outlets switch independently
- Sunrise and sunset scheduling with offset
- Wi-Fi reach up to 300 feet
- Works with Alexa and Google Home
- Quick Kasa app setup
- 2.4GHz Wi-Fi only
- 6-inch cord is short for recessed boxes
The EP40 is the plug we ended up recommending to friends first, and the reason is narrow. Most holiday displays are not one run of lights. They are two or three: the warm white strand along the gutter, the cool white strand on the shrubs, and the lit wreath on the door. The EP40 puts two independently switched outlets behind one 6-inch cord, so the eaves strand can run on a sunset schedule while the shrubs stay off until 8pm.
Both outlets are rated 15A/1875W, which matters more than it sounds. A single 15A circuit is the whole budget you have, and the plug does not add capacity to it. It simply refuses to be the weak link.
Setup took under five minutes on a 2.4GHz network, and the Kasa app has the scheduling tools this use case needs: a weekly timer, plus sunrise and sunset triggers with an offset you can nudge by a few minutes in either direction. That offset matters in December. Sunrise in late December can be later than the time you want lights on, and a fixed 5pm timer means your display runs in daylight for weeks.
The long-range claim is 300 feet, and in practice that covers a house where the exterior receptacle sits on the far side of the brick from the router. Users on the Home Assistant community forums have run Kasa outdoor plugs for landscape lighting, pond pumps and holiday lights for years, describing them as a no-complaint workhorse. The one thing that model does not do is report wattage.
Two independent outlets are the reason this one wins
Almost every competitor in this roundup switches both outlets together, which means one timer for everything plugged in. If your display has two runs that need different hours, you either buy two plugs or accept identical timing. The EP40 solves it in the box.
The 300-foot rating also removes the most common outdoor failure: a plug that drops off the network when it is mounted at the far end of the driveway.
Skip it if you need dimming or a waterproof shell
The IP64 rating is excellent for covered and semi-covered mounting, but it is not the right choice for an open garden stake with no roof over it. If your receptacle is fully exposed, look at the IP65 models further down.
It also needs 2.4GHz Wi-Fi. If your router has split bands and 2.4GHz is disabled, this plug will not join. The 6-inch cord is short, so a recessed or deep weatherproof box may not give the body enough room to sit flat.
2. TREATLIFE Outdoor Dimmer Plug: Dimmable String Lights on a Budget
- Dims dimmable string lights
- Sunrise and sunset scheduling
- Group control and vacation mode
- Works with Alexa and Google Assistant
- Physical button for manual control
- Works with dimmable bulbs only
- Schedule resets after power loss
- Short 1ft cord
A lot of holiday string lights sold as dimmable are not, and the ones that are usually only dim through a physical controller. The TREATLIFE DP10 moves that dimming into the app and into Alexa, so you can bring a strand up to 40 percent at sunset and push it to full after dinner. The rating is 4.4 across more than 10,000 reviews, which makes it one of the most proven dimmers we looked at.
The max power figure is 400W for incandescent and 150W for LED or CFL. Almost every modern string light falls well under that, so the ceiling rarely matters. What matters more is the hard restriction: dimmable bulbs only. It will not run a pump, a fan, or a non-dimmable strand.
The app carries group control and vacation mode, so a display can flicker to a different pattern while you are away, which is a deterrent worth having if your lights run near a street. There is also a physical button on the plug itself, so you can trigger the lights without opening the app when you are already standing outside.
The downside that showed up most in owner feedback is schedule loss after a power cut. Holiday displays are exactly the setups that see brownouts and storm outages, and a dimmer that forgets its schedule needs a manual reset each time the power comes back.
Buy it if your strings are dimmable
If your lights advertise dimming, this is the cheapest way to get app and voice control over that dimmer. Voice control for brightness is something none of the on/off plugs in this list can do.
IP44 suits a covered porch or a patio roof. Pair it with a weatherproof receptacle cover and it holds up through a normal winter.
Skip it if you need two runs or outage-proof timing
It is a single-outlet dimmer, so a second light run means a second plug and a second schedule to manage.
Lost schedules after an outage and the 1-foot cord are the two complaints to weigh. If your display is on a circuit that browns out during heavy storms, choose a model that keeps its schedule instead.
3. Kasa Outdoor Smart Dimmer KP405: IP64 Rating Meets Dimming
- Higher IP rating than most dimmers
- Works with SmartThings Alexa and Google
- Dimming control through the Kasa app
- 300ft Wi-Fi reach
- UL94-V0 fire-resistant housing
- Only drives dimmable lights
- Some reports of failure after rain exposure
- 2.4GHz only
The KP405 is the TREATLIFE answer for anyone who wants dimming without dropping to IP44. IP64 means a better seal around the internals than a splash-rated housing, and the UL94-V0 polycarbonate shell is rated for flame and heat resistance, which is a real consideration when the plug sits next to a strand drawing several hundred watts.
It handles 300W on incandescent and 150W on LED or CFL, and it runs on a 2.4GHz network with a stated reach of 300 feet. Mounting uses a clamp and screw rather than a bare plug, so you can fix it to a post or a stake and take strain off the receptacle.
SmartThings support is the detail that separates it from most outdoor dimmers. Alexa and Google Assistant cover most people, but SmartThings opens up routines that can tie the display to a doorbell or a presence sensor, and it is the ecosystem most Home Assistant users are already running.
The honest caveat is durability. Some owners report units failing after extended rain exposure, which is a reminder that IP64 is a rating against water, not a promise of indefinite service. Owners also report occasional scheduling quirks around time zone settings and the off-timer.
It suits covered spots that need dimming
Choose this when you want a dimmer and your receptacle is anywhere near open sky. IP64 and a clamp mount are both upgrades over a splash-rated inline dimmer.
The 2-year warranty and ETL listing give it more backing than most dimmers in the category.
Skip it if you need two runs or non-dimmable lights
One outlet, dimmable loads only. A pump, a projector, or a standard non-dimmable strand will not work through this plug.
Rain exposure reports are not widespread, but they exist. If the plug sits fully exposed with no cover, an IP65 model is the safer pick.
4. Meross Outdoor Smart Plug: Built for Apple Home
meross Outdoor Smart Plug Work with HomeKit, Alexa, Google and SmartThings
- Apple HomeKit and Siri support
- Two independent outlets
- Works across five ecosystems
- Mediatek chipset for range
- Fire-retardant housing with overload protection
- HomeKit remote needs an Apple home hub
- IP44 is not an exposed-location rating
- Not intended for pump loads
Apple HomeKit support is rare on an outdoor plug, and meross is the clearest example. If your household runs on Home, this is the outdoor plug that shows up in the Home app next to your indoor devices and answers to Siri without a separate bridge.
Both outlets switch independently, both are rated 15A, and the fire-retardant housing includes overload protection. The Mediatek IoT chipset is the reason owners report fewer dropouts than with some competing outdoor plugs.
One catch for Apple users: the HomeKit remote control feature needs an Apple home hub such as a HomePod or Apple TV. Without one, you still get on/off and schedules in the Home app, but you lose access from outside the home.
It also runs on Amazon’s AWS servers for its cloud side, which is worth knowing if you prefer local control. The IP44 rating means a covered or sheltered mounting, not an open stake.
It is the pick when Siri runs the house
Very few outdoor plugs support HomeKit, and this one also covers Alexa, Google Assistant and SmartThings for mixed households. The two independent outlets and 15A rating per socket match the class leaders.
Overload protection and a fire-retardant housing make it a sensible choice for a display that runs long hours.
Skip it if you need exposed mounting or hub-free HomeKit
IP44 means covered locations. An open garden receptacle needs IP65.
If you run Home Assistant or Hubitat and care about local control, note that the meross app depends on cloud servers, and the reviews include reports of intermittent connectivity.
5. GE Cync Outdoor Smart Plug: Bluetooth Setup Backup
GE Cync Smart Plug, Outdoor Bluetooth and Wi-Fi Outlet Socket, Weather Resistant Plug, Works with Alexa and Google, Black (1 Pack)
- Bluetooth fallback for setup
- No hub required
- Works with Alexa and Google Assistant
- 15A rating
- Reliable once configured
- Cync app setup can be difficult
- Some router compatibility issues reported
- No stated IP water rating
The Cync plug pairs over Bluetooth as well as Wi-Fi, which solves a problem most outdoor plugs do not: the moment you most want to pair a plug is when you are standing outside with a ladder, a phone, and a weak signal. Bluetooth gets the device onto the network without needing a strong Wi-Fi handshake.
It runs a 15A rating with weather-resistant outlet covers, needs no hub, and works with Alexa and Google Assistant through the Cync app.
What you give up is polish. Owners consistently report that setup is the hardest part: the app instructions are thin, and there are reports of router compatibility problems with certain Netgear models. Once configured, reliability improves noticeably.
Worth checking if you are outside the US.
Bluetooth onboarding is the practical win
If your exterior receptacle sits at the edge of your Wi-Fi range, the Bluetooth pairing route is the reason to pick this over an equivalent plug without it.
A 15A rating and weather-resistant covers make it a safe default for a covered holiday run.
Skip it if setup friction would bother you
This is the pick with the most reported onboarding complaints in our set, and some routers need troubleshooting before it will connect.
No IP water rating is stated on the listing, so treat it as a covered-location plug rather than an exposed one.
6. Geeni Outdoor Duo 2-Pack: Four Exposed-Ready Outlets
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
- IP65 rating holds up to water jets
- Four outlets across two plugs
- No additional hardware needed
- Works with Alexa and Google Assistant
- Schedules and timers in the Geeni app
- 2.4GHz Wi-Fi only
- Geeni app is a separate ecosystem
- Alexa and Google only
- no HomeKit
The Geeni Outdoor Duo is the value play for an uncovered yard. It carries an IP65 rating, which means dust-tight and protected against water jets from any direction, and each plug gives you two weatherproof outlets. The 2-pack gives you four total, which is enough to run a front garden and a side path from two separate receptacles.
For most people, buying two and splitting them across the property is the practical move. A single-location plug with a long extension cord back to the house is a trip hazard in December.
It works with Alexa and Google Assistant, needs no hub, and the Geeni app handles schedules and timers. Both outlets on a plug share a schedule, so this is a good fit when the two strands on one receptacle genuinely turn on and off together.
The trade-off is ecosystem. Geeni is its own app, and there is no HomeKit or SmartThings support. If your household already has everything in one platform, that matters more than the IP rating.
It is built for open-air mounting
IP65 is the rating that lets a plug live on a stake or in an uncovered box in rain. If your lights are exposed, this is the pair to buy.
Four outlets from a two-pack is more coverage per box than any other product here, which suits a display with many small runs.
Skip it if you run HomeKit or need separate schedules
Alexa and Google Assistant are the only voice platforms listed. Apple and SmartThings users should look at the meross or Feit models.
Both outlets on each plug are switched together, and 2.4GHz is required for the network.
7. Amazon Basics Outdoor Smart Plug: Alexa Without the Extra App
- IP65 rating for exposed locations
- Zero-touch setup linked at checkout
- No separate app to install
- Two independent outlets
- UL certified
- Alexa only with no Google or HomeKit
- 2.4GHz Wi-Fi only
- No energy monitoring
If Alexa is the only voice assistant in the house, this is the shortest path from box to working display. There is no separate app to install. Linking happens at checkout through the Alexa app, and both outlets are individually controlled once it is done.
The IP65 enclosure is the other reason to look here. Outlets that are Alexa-only often trade away weather sealing, and this one does not.
It is UL certified and rated 15A. That is the full 1,875W on a 120V circuit, so a display with several LED strands sits well inside the limit.
Setup through the Alexa app also means schedules and routines live in the same place as the rest of your Amazon devices, which some households find easier than maintaining a second app for four holiday weeks.
It removes the app from the equation
No hub, no third-party app, no second account. That is genuinely less to go wrong in the middle of a decorating session.
Combined with the IP65 enclosure, it handles an exposed receptacle and voice control in one unit.
Skip it if your home is not Alexa-only
There is no Google Assistant, HomeKit, or SmartThings path here. If anyone in the house uses a different assistant, the lock-in is total.
There is also no energy monitoring, so you cannot see what a display costs from the app.
8. Wyze Plug Outdoor: Energy Monitoring on a Light Run
Wyze Plug Outdoor, Dual Outlets Energy Monitoring, IP64, 2.4GHz WiFi Smart Plug, Works with Alexa, Google Assistant, IFTTT, No Hub Required, Black
- Reports live wattage and energy use
- IP64 weather resistance
- Wi-Fi and Bluetooth
- Works with Alexa Google and IFTTT
- Two outlets in one body
- Outlets switch together with no independent control
- Energy data needs the Wyze app
- 2.4GHz only
The Wyze Plug Outdoor is the only product here that reports what your display is actually drawing. It logs live wattage and accumulates energy use, which turns a holiday estimate into a real number you can check each week in December.
It is also one of the few outdoor plugs here with both Wi-Fi and Bluetooth, plus IFTTT support for automations that go beyond the manufacturer’s app.
The catch is outlet control. Both outlets switch together, so you cannot put the gutter strand on a different schedule than the shrubs. The IP64 rating is good, and the 15A ceiling is standard, but there is no independent switching anywhere on this unit.
Energy data lives in the Wyze app. That is a fair trade for people who like seeing numbers, and a poor one if you only want a timer.
Energy data answers a real question
Once you know the wattage your display pulls, you can size it properly and see whether a second run is worth adding. Most competitor apps give you an on/off switch and nothing else.
IFTTT is a bonus for anyone whose automations already live somewhere other than the Wyze ecosystem.
Skip it if you need two separate schedules
Both outlets are ganged together. Two runs with different hours need a different plug.
The monitoring data also requires the Wyze app, and the rubber housing is a material some owners expect to age faster than plastic.
9. Feit Electric Dual Outlet Plug: HomeKit on a Wet-Location Rating
- HomeKit support at a low price
- Multiple daily schedules with day selection
- ETL wet location rated
- Works with Alexa and Google Home
- Compact body
- Outlets switch together
- One-year warranty only
- Short stiff cable
The Feit plug earns its place on one combination that rarely shows up together: Apple HomeKit support, a wet-location ETL rating, and a price near the bottom of the category. For an Apple household running a covered holiday run, there is no cheaper way in.
Its app is also the strongest scheduler among the simpler plugs here. You can build multiple daily schedules with day selection, which is how you run a weekday-only display versus a full weekend one.
Both outlets switch together, so this is a one-schedule plug. The dimensions are small enough to fit in a shallow weatherproof box where a bulkier two-outlet body would not seat properly.
Two build details are worth noting. The safety covers that close over the sockets are reported to fall out easily, and the cable is short and stiff. The warranty is one year, half what Kasa and TREATLIFE offer.
It covers three voice platforms in one unit
Alexa, Google Assistant, and HomeKit from a single plug is unusual in the outdoor category, and the Feit app handles day-by-day scheduling better than most.
The wet location rating makes it a reasonable choice for a covered receptacle in most climates.
Skip it if you want independent outlets or a long warranty
Both outlets switch as one. A display with two different schedules needs a different model.
Owners also report needing a reset after moving the plug to a different network, and the one-year warranty is the shortest here.
10. DEWENWILS Yard Stake Plug: Six Outlets on One Schedule
DEWENWILS WiFi Smart Yard Stake Timer Plug, Outdoor Power Stake Timer
- Six outlets for a whole display area
- 6ft cord reaches away from the wall
- Stake or wall mount
- Overload protection switch
- Alexa and Google Assistant support
- All six outlets switch together
- Bulky body and cover will not close when full
- Reports of timer reliability issues
The DEWENWILS stake is the odd shape out, and for large displays that is the point. It mounts into the soil or onto a wall, runs a 6ft heavy-duty cord back to the receptacle, and gives you six grounded outlets in one weatherproof body.
That solves the yard problem. Instead of four extension cords and three plugs, you have one schedule for the entire area.
It carries an overload protection switch, fireproof polycarbonate construction, and an IP44 cover, plus Alexa and Google Assistant support with dusk-to-dawn scheduling through the app. Rated 15A/1875W resistive and 8A/1000W for tungsten, so it is built for light strings rather than for anything motor-driven.
The trade-offs are physical. Six sockets in a sealed body is a lot of volume, and owners report that the cover will not close when all six are occupied by large plugs. Some owners of these models also report timer reliability issues and display problems.
One schedule for a whole display zone
When everything in one area turns on and off together, six outlets on a stake is far cleaner than six extension leads. The 6ft cord is what makes it usable at all.
It is also the only pick here that works as a self-contained yard unit, so it suits a garden with no convenient wall.
Skip it if runs need different hours
All six outlets are ganged together. Any display that needs separate timing rules out this plug.
The 4.2 rating is the lowest in our set, and the bulky body plus cover complaints mean it suits a tidy, planned install rather than a quick one.
How to Choose an Outdoor Smart Plug for Holiday Lights in 2026?
Match the plug to the location first, then to the load, then to the ecosystem. Everything else is preference. Here is the order we use, and the six questions worth answering before you buy.
Which IP rating do you actually need?
Under a roof, a soffit, or a covered box, IP44 is enough. On an open stake or an uncovered receptacle, go to IP65. IP64 sits in between and is the safest default when you are not certain how much water the socket gets.
Mount vertically with the outlets facing down so water runs off rather than pooling on a seal. This one habit does more for plug life than any rating on the box.
How many light runs can one plug handle?
Do the arithmetic on the whole circuit, not the plug. A 15A/1875W plug is a 1,875W ceiling, and everything on that circuit shares the same limit.
Most modern LED string lights draw a small fraction of that. A 200-light LED strand typically runs tens of watts rather than hundreds, so a typical display of four to six strands sits comfortably inside one 15A outlet. Old incandescent strands are a different story, and the TREATLIFE and Kasa dimmers carry lower ceilings specifically because dimming circuits carry more current.
If you are unsure, check the wattage printed on the light set and add it up before plugging anything in.
Does your Wi-Fi reach the socket?
Every outdoor plug in this roundup is 2.4GHz only. If your router splits bands and 2.4GHz is switched off, nothing here will connect. The practical bands we use: under 50 feet and one exterior wall is fine, 50 to 100 feet through brick or an exterior wall often needs help, and beyond that a mesh node near the receptacle is the fix.
Two products here pair over Bluetooth as well as Wi-Fi, which helps with setup when the signal at the socket is weak. Pair multi-packs one unit at a time, with your phone near the first plug, because owners on smart home forums report that adding several devices at once is the main cause of plugs stuck on unable to connect.
Which ecosystem should decide it?
Almost every outdoor plug here works with Alexa and Google Assistant. The differentiators are elsewhere: HomeKit support on the meross and Feit plugs, SmartThings on the Kasa KP405, IFTTT on the Wyze, and Alexa-only on the Amazon Basics model with no extra app at all.
If you run Home Assistant or Hubitat, favour local control and check whether the brand works without its own cloud. Our smart plug picks for a home office cover the indoor side of that decision.
What should you never plug in?
Space heaters, hair dryers, portable air conditioners, and medical devices do not belong in a smart plug. These draw high current and, in several cases, cycle on a thermostat that does not expect to have its power cut remotely.
Any appliance with a momentary button is also a poor fit, because the plug has no way to press it. Devices with a physical on/off switch restore correctly. For indoor mood lighting outside the holiday season, our smart ambient light guide for movie rooms covers the setups that still need one.
What should you do after the holidays?
Unplug outdoor plugs in January and bring them inside. A plug left energised in a weatherproof box all spring and summer is running a device nobody is using, and it ages the seals and the electronics for nothing.
Wipe the cover, dry the cord connection, and store it in a drawer. If a plug was sitting in snow or standing water, check the seal when you bring it back out in November. A ten-minute January task is worth doing every year.
Frequently Asked Questions
What is the best smart plug for controlling outdoor lights?
The Kasa Outdoor Smart Plug EP40 is the strongest all-round choice, with two independently switched outlets, an IP64 rating, and 15A per outlet. For a fully exposed receptacle with no cover, pick an IP65 model such as the Geeni Outdoor Duo or the Amazon Basics Outdoor Smart Plug.
Can a smart plug be used outdoors?
Only a plug rated for outdoor use. Indoor smart plugs are not sealed against moisture and are unsafe in rain or snow. Outdoor models carry an IP code, and anything from IP44 upward is suitable for holiday lights when mounted on a GFCI-protected receptacle.
Which brand is considered the best for smart plugs?
It depends on your ecosystem rather than the brand. Kasa covers Alexa and Google Assistant, meross adds Apple HomeKit, Feit supports all three major voice platforms, and Amazon Basics is the simplest choice if Alexa is your only assistant.
What devices should not be used with smart plugs and why?
Space heaters, hair dryers, portable air conditioners, and medical devices should not run through a smart plug because of high current draw and thermostat cycling. Appliances with momentary push buttons also fail to restart correctly, since the plug has no way to press the button.
What are the disadvantages of smart plugs?
Every outdoor model here needs 2.4GHz Wi-Fi, most rely on a phone app and a cloud account, and none schedules through a lost internet connection with the reliability of a mechanical timer. Outdoor plugs also sit exposed to weather, so IP rating matters, and a few models switch both outlets together rather than independently.
Will a smart plug work after a power outage?
It depends on the model. Most restore their last on or off state, but some dimmers lose their saved schedule after an outage and need a manual reset, which is worth checking if your display sits on a circuit that browns out during storms.
Our Final Verdict on the Best Smart Plugs for Holiday Lights in 2026
The best smart plugs for holiday lights are outdoor-rated, split into two independent outlets where your display has more than one run, and matched to an IP rating that suits how exposed the receptacle really is. The Kasa Outdoor Smart Plug EP40 takes our top spot because it does all three without asking you to compromise, and it is the model we would put on a roofed porch without hesitating.
For exposed locations, move up to an IP65 body. For dimmable strands, take the TREATLIFE or the Kasa KP405, and accept the loss of the second outlet. For Apple homes, the meross is the one with HomeKit on an outdoor shell. And for a display spread across a whole yard, the DEWENWILS stake replaces a pile of extension cords with one schedule.
Whichever you pick, mount it on a GFCI receptacle, keep it out of the snow line, and pull it out of the wall come January. If you want a second opinion before buying, our holiday projector roundups cover the lighting side of the display.
