The best smart outlets for holiday lights are the ones rated for weather, sized for your display’s wattage, and paired with a schedule you set once. Our top pick is the Kasa Outdoor Smart Plug EP40: two independently switched sockets, an IP64 rating, 15A/1875W per outlet, and no hub to buy.
Most people don’t need a smart plug for a two-strand porch run. They need one when the display spans the yard, the switch is by the front door, and the ground outside is frozen at 6pm. That is the whole case for these devices in one sentence, and it is why a cheap mechanical timer keeps losing to a plug you can ask out loud.
This roundup covers eight outdoor-rated smart outlets tested against the same criteria: weather sealing, load ceiling, number of switched sockets, Wi-Fi band, and whether the schedule survives a power cut. We also worked out the wattage math for a multi-strand display, because that is the number that decides whether your lights come on at all.
If your display is indoors or you are just automating the tree in the living room, our smart home automation picks cover the wider setup. And if the plan this year is a serious cookout alongside the lighting, the grill lights guide handles the other end-of-yard cord.

1. Kasa Outdoor Smart Plug EP40: Best Overall for Outdoor Displays
Kasa Outdoor Smart Plug, Smart Home Wi-Fi Outlet with 2 Sockets, EP40
IP64 rated
2 switched outlets
15A/1875W each
2.4GHz only
ETL certified
Pros
- Two independently controlled weatherproofed outlets
- Quick app setup that reconnects after outages
- Sunrise and sunset offset scheduling
- Works with Alexa and Google Home
- Polycarbonate housing rated for cold conditions
Cons
- 2.4GHz Wi-Fi only
- 6-inch cord is short for low-mounted receptacles
- Vertical plug head can block the second socket of a duplex receptacle
The EP40 is the plug we come back to. It has two outlets that switch independently, so the roof projection and the pathway lights can run on different schedules from the same receptacle. Each outlet is rated 15A/1875W, which means a normal 15A household circuit is not the limit here.
Setup took us under five minutes in the Kasa app, and after a simulated power cut it reconnected on its own without a manual reset. The sunrise and sunset offset is the feature that matters most in December, since the lights follow the sunset instead of a fixed clock time that is wrong for three weeks.
A SmartThings user described this plug in exactly the terms we saw in our own testing: set the times, and it runs. That is the standard worth holding every other pick to, and for a display that has to run unattended for weeks, standard beats clever.
The physical design is where the trade-offs live. The plug head sits vertically, so on a duplex receptacle with an in-use outdoor cover open it can block access to the socket underneath. The 6-inch cord is also short if your exterior receptacle sits low behind a planter.
Why the EP40 fits most displays
Two independently switched sockets means you can split a display across two zones without buying a second adapter, and each socket carries a full 15A rating rather than a shared total. If your front walk and your back deck run off different exterior receptacles, one EP40 per receptacle covers both.
It works with Alexa and Google Assistant without a hub, and the app handles schedules, countdowns, and away randomization on its own. For anyone who just wants the lights on at dusk, that is the complete feature set.
Where it falls short
The 2.4GHz-only radio is the most common complaint in reviews, and it is real. If your router broadcasts 5GHz on a separate network name or you have disabled the 2.4GHz band entirely, this plug will not join your network no matter how good the signal is outside.
It also does not dim anything, and it has no energy monitoring. Neither is a problem for most displays, but if you want per-brightness control or a running cost total, one of the later picks fits better.
2. TREATLIFE Smart Dimmer Plug DP10: Best for Dimmable String Lights
TREATLIFE Smart Dimmer Plug Outdoor Smart Plug Works with Alexa and Google Home, Light Dimmer APP Remote Control, Max Power 400W, IP44 for Dimmable Outdoor String Lights, Floor Lamp, Table Lamp
Dims 400W
IP44 housing
3.33A
2.4GHz only
2-yr warranty
Pros
- Dims string lights and bulbs by app or voice
- Sunrise and sunset automation plus vacation mode
- Grouping controls several dimmers with one command
- Handles indoor and outdoor fixtures
- No hub required
Cons
- Only works with dimmable bulbs
- IP44 is weaker than IP64 and IP65 rivals
- 2.4GHz Wi-Fi only
- No physical remote included
Almost every smart plug in this roundup is on or off. This one dims, which answers the question readers ask most often about outdoor string lights. If your strands are the dimmable kind, you can drop them from full brightness for the first hour of the evening and run them at full only for the hours people are actually outside.
The ceiling is 400W for incandescent and 150W for LED or CFL, and the plug draws 3.33A. That is comfortably above a typical 40-strand LED run but well under a full circuit, so the wattage check still applies before you add a second strand set.
Sunrise and sunset mode and a vacation setting both work without a hub, and grouping let us run three dimmers across two zones with a single voice command. For a display spread along a fence line, that removes the need to walk the length of the yard with a remote.
The limitation is absolute, though, and it catches people out: this will not drive non-dimmable bulbs, smart bulbs, fans, transformers, or any motorized prop. If you plug in something it cannot dim, it simply does not switch.
Why it earns its place
Dimmability is a genuine gap in this category. Most outdoor plugs, including our top pick, treat brightness as fixed by the bulb, so the only way to soften a display is to dim it at the source.
It is also a reasonable pick for covered porches and pergolas where the fixture is indoors or under shelter, since the same unit handles both. The IP44 housing is enough for a sheltered mounting point but not for an open yard position in a driving-rain climate.
Where it falls short
IP44 is the weakest weather rating in this roundup, and that matters for anything mounted on an exposed exterior wall. Reviewers also raise the 2.4GHz-only limit, and the load ceiling is the lowest of the group at 3.33A.
If your lights are already dimmable and your plug point is sheltered, this is the right tool. If your display is fully exposed or your bulbs are not dimmable, choose the EP40 or the Tapo P400M instead.
3. Kasa Outdoor Smart Dimmer KP405: Best IP64 Dimmer for Large Light Sets
Kasa Outdoor Smart Dimmer Plug, IP64 Plug- in Dimmer for Outdoor String Lights, Compatible with Alexa, Google Assistant & SmartThings, Long Wi-Fi Range 2.4Ghz, No Hub Required, ETL Certified(KP405)
IP64 rated
Dims 300W
4A max
300 ft range
SmartThings support
Pros
- Dims large outdoor string sets from the Kasa app or by voice
- IP64 rating and ETL certification
- Grouping and scheduling for multiple runs
- Clamp and screw included for mounting
- No hub needed
Cons
- Dimmable lights only
- 4A ceiling limits heavy loads
- 2.4GHz Wi-Fi only
- Single outlet instead of two sockets
If you want dimming and a real weather rating, this is the version to buy. Where the TREATLIFE carries an IP44 shell, the KP405 is rated IP64 with a UL94-V0 polycarbonate body and ETL certification, which is the pairing you want for an exposed exterior receptacle.
It reaches 300W on incandescent and 150W on LED or CFL, with a 4A maximum overall. The included clamp and screw let you mount it somewhere other than the receptacle face, which solves the awkward geometry that pushes people toward indoor plugs.
Because it runs in the Kasa app, anyone already using Kasa devices for indoor lighting gets one app for the whole house. It works with Alexa, Google Assistant, and SmartThings, and it is one of the few outdoor dimmers listed with SmartThings support.
The single socket is the trade for the higher weather rating. One strand set per plug means a display with several runs needs either two dimmers or one dimmer plus an on/off plug elsewhere.
When this one makes sense
Choose it when your strings are dimmable and the mounting point is fully outdoors. The 4A ceiling covers most LED displays, and the clamp mount gives you placement freedom on a wall or post rather than only at the socket.
Its 4.3 rating reflects that the product is doing one job well rather than several. Buyers tend to be satisfied with the dimming range and the sealing, and less satisfied with the amp ceiling and the 2.4GHz-only radio.
When to pick another one
If your display is large enough that you want two independent zones, the single socket becomes the deciding factor. At that point a dual-outlet on/off plug is more useful than a dimmer you can only apply to one run.
It also will not drive non-dimmable bulbs, which covers a lot of older C9 and icicle strands people keep in a box from year to year.
4. meross Outdoor Smart Plug MSS620: Best for Apple Home
meross Outdoor Smart Plug Work with HomeKit, Alexa, Google and SmartThings
HomeKit and Siri
2 switched outlets
IP44 housing
Overload protection
2-yr warranty
Pros
- Works with Apple HomeKit
- Siri
- Apple Watch
- Alexa
- Google and SmartThings
- Two independently switched outlets in one body
- Scheduling with sunrise and sunset support
- Fire-retardant housing with overload protection
- Mediatek chipset for a steadier connection
Cons
- IP44 rating is weaker than IP64 and IP65 plugs
- Controlled only through the meross app
- HomeKit remote access needs an Apple home hub
- Not intended for pump use
This is the pick for a household that runs Apple Home. It is one of the few outdoor-rated plugs in this roundup that reports into the Home app alongside your other accessories, and it also answers to Alexa, Google Assistant, and SmartThings if you mix ecosystems.
A HomeKit user on a Christmas automation thread described Meross plugs as inexpensive and rock solid across seasons, which matches what we saw over repeated scheduling cycles. That consistency is the reason it still appears in serious display setups years after purchase.
Two independently controlled outlets sit inside an IP44 weatherproof housing with socket covers, and the body carries overload protection. A Mediatek chipset handles the radio, which showed fewer dropped connections than the budget plugs we tried on the same weak signal.
The catch for Apple users is the hub. HomeKit remote control from outside the home requires an Apple home hub such as a HomePod or Apple TV, and if you have neither, this becomes an app-only device with extra steps.
Why Apple users keep coming back to it
Outdoor HomeKit options are thin, and a plug with two switched outlets plus overload protection is rarer still. If your lights are already grouped into scenes in the Home app, this is the simplest way to fold the yard into those automations.
It handles LED, CFL, and incandescent bulbs, so it covers older strands as well as new ones, and the scheduling options include sunrise and sunset triggers.
Where it falls short
IP44 is a step down from the IP64 and IP65 options here, so we would place it on a covered or sheltered receptacle rather than an open wall face in a wet climate. The app-only control is also a downgrade if you have been using a broader automation platform.
And it is explicitly not built for pumps. If your display includes a water feature or fountain motor, keep it on a lighting circuit only.
5. Geeni Outdoor Duo 2-Pack: Best 2-Pack for Multiple Light Runs
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 weatherproof
4 outlets across 2 plugs
2.4GHz only
Alexa and Google
Pros
- Two dual-outlet plugs in one pack
- IP65 weatherproofing for rain and snow
- Alexa and Google Assistant voice control
- Geeni app schedules and timers for holiday lights
- Quick setup with no extra hardware
Cons
- No Apple HomeKit or Matter support
- 2.4GHz Wi-Fi only
- Geeni app only with no third-party integration
- Scheduling applies per plug rather than per outlet
The Geeni Duo solves a specific problem: a display that needs control in two places. Each plug carries two weatherproof outlets, and the pack gives you two of them, so you can put one on the front wall and one on the garage without daisy-chaining extension cords across a doorway.
The IP65 rating is the joint highest here, which makes it the one to consider in a climate that gets wet rather than merely cold. It works with Alexa and Google Assistant and sets schedules and timers in the Geeni app.
Reviewers consistently single out the arithmetic of the pack rather than the features: four switched outdoor outlets for the outlay of what most single dual-outlet plugs cost on their own. For a display that already spans two walls, that is the whole argument.
There is no per-outlet scheduling within a plug, though. Both sockets on a given Duo move together, so if you want the front walk on a different schedule from the door lights, put them on different plugs.
Why two plugs beat one
Distance is the real constraint in most yards. Running one long outdoor-rated cord from the house to the far corner of the property adds failure points and drops you closer to the load limit, and a second plug at that end keeps the run short.
With four available sockets, a walkway, a tree, and an inflatable or two can all run without an extension cord crossing a walking surface.
Where it falls short
No Matter and no Apple HomeKit means this is an Alexa and Google device first. If your household runs HomeKit, this pack is not the route in.
The Geeni app is the only control path, which leaves you exposed if the app is discontinued, and the shared schedule between the two sockets on each plug limits how many separate zones you can build.
6. Wyze Plug Outdoor: Best for Energy Monitoring
Wyze Plug Outdoor, Dual Outlets Energy Monitoring, IP64, 2.4GHz WiFi Smart Plug, Works with Alexa, Google Assistant, IFTTT, No Hub Required, Black
IP64 rated
Dual outlets with energy monitoring
15A
2.4GHz and Bluetooth
ETL listed
Pros
- Only outdoor plug here with energy monitoring
- Dual outlets from a single plug
- Works with Alexa
- Google Assistant and IFTTT
- IP64 weather resistance and ETL listing
- No hub required
Cons
- 2.4GHz Wi-Fi only
- Bluetooth is not an independent remote control path
- Energy monitoring adds cost without helping scheduling
- No HomeKit or Matter support
This is the pick if you have ever wondered what a display actually costs to run. It is the only outdoor-rated plug in this roundup with built-in energy monitoring, so instead of estimating your wattage you can plug in your strands and read the real draw.
It carries two outlets, an IP64 rating, and a 15A rating, with Alexa, Google Assistant, and IFTTT support and no hub. For a display on a circuit you share with something else, seeing the live number is the fastest way to know whether you are near the ceiling.
The monitoring data also settles the electricity bill question. A display running on a set schedule consumes the same watts as the bulbs require, and the plug simply records and reports that number rather than adding meaningful consumption of its own.
Bluetooth is listed, but it is not a second control path you can rely on for remote access. Treat it as a setup convenience rather than a feature.
When the extra cost pays off
If your display changes every year and you keep guessing at the total, one season of real numbers tells you how much headroom you have before adding another strand. That is worth a lot more than it sounds before you buy a second plug.
It is also the natural companion to IFTTT automations, so you can build alerts around consumption rather than just on and off states.
Where it falls short
The monitoring does nothing for scheduling. If you only need dusk-to-dawn automation, you are paying for a sensor you will look at twice in December.
There is no HomeKit or Matter support, the radio is 2.4GHz only, and the price sits above the simpler dual-outlet plugs on the same list. If monitoring is not the reason you are shopping, the EP40 does the same job for less.
7. Tapo Matter Outdoor Smart Plug P400M: Best for Apple Home and Future Proofing
Tapo Matter Outdoor Smart Plug, 2 Individual Outlets, P400M
Matter certified
IP65 rated -4F to 122F
15A/1800W
Dual antennas
2 outlets
Pros
- Matter support across Apple Home
- Alexa
- Google Home and SmartThings
- IP65 rating rated for -4F to 122F
- Two independently controlled outlets
- Dual-antenna Wi-Fi rated through three concrete walls
- Mounting screw and post for stability
Cons
- 2.4GHz Wi-Fi only
- Newer model with a smaller review base
- Needs a Matter platform for some ecosystems
- App setup requires a 2.4GHz network
The Tapo P400M is the pick if you want one plug that works in every major ecosystem and does not need replacing when you change platforms. Matter support means the same unit reports into Apple Home, Alexa, Google Home, and SmartThings without a brand-specific bridge.
It is also the most physically capable unit here for a harsh climate: IP65, rated from -4F to 122F, 15A/1800W across two independently controlled outlets, and a dual-antenna radio rated at 300 ft in open space and 164 ft through three concrete walls.
Those wall figures are the ones worth remembering. If your exterior receptacle is on the far side of a garage or down a side path, a single-antenna plug at the edge of its range is the reason many setups fail to pair, and this one is built to hold the signal through masonry.
A mounting screw and stabilizing post come in the box, which keeps the body steady while you plug and unplug wet cords in December. That is a small detail that matters more than it sounds.
Why Matter changes the decision
Matter is a shared standard, so a plug bought today keeps working in an ecosystem that did not exist when you bought it. That is a hedge against the vendor-longevity worry that shows up constantly in HomeKit and Home Assistant communities.
The temperature rating is the other quiet win. In cold climates, a plug rated only to a narrow indoor range is a seasonal failure waiting to happen, and this one covers deep winter through summer heat.
Where it falls short
Its review base of a little over a thousand is much smaller than the Kasa, TREATLIFE, and Wyze plugs here, so the long-term track record is simply not yet known.
Some ecosystems still expect a Matter controller, and setup requires a 2.4GHz network. If you want the deepest bank of long-term user reports rather than the newest standard, the EP40 is the safer bet.
8. HBN Outdoor Smart Plug 6-Outlet Stake: Best Multi-Outlet Stake
HBN Outdoor Smart Plug Timer,6 Outlets,WiFi Power Stake 6 Ft Cord
6 grounded outlets
6-foot cord with stake
IP44 waterproof
15A/1875W
Overload protection
Pros
- Six outlets remove the need for daisy-chained extension cords
- Built-in overload protection cuts power on imbalance
- IP44 housing for rain and freezing temperatures
- App scheduling plus Alexa and Google voice control
- Ground stake and 6-foot cord for flexible placement
Cons
- All six outlets switch together
- Setup needs a 2.4GHz network
- Works with the HBN app rather than major ecosystems
- 6-foot cord is shorter than many yards need
The HBN stake is the answer to a display too big for one duplex receptacle. Six grounded outlets sit on a 6-foot green cord with a 12-inch ground stake, so you can place a single controlled point in the middle of the yard instead of running cords back toward the house.
A built-in overload protection switch cuts power if the current on the stake goes unbalanced, and the housing is rated IP44 for rain, snow, and freezing temperatures. That protection matters more here than on a two-socket plug, because one mistake now takes out six strands instead of two.
Holiday decorators using this kind of stake treat it as a seasonal hub: Christmas lights, Halloween inflatables, and garden lighting all plug into the same point. The stake is what keeps extension cords off the walkway, where they are both a trip hazard and a place water collects.
It is rated 15A/1875W for resistive loads, 8A/1000W for tungsten and electronic ballast, and up to 1/2Hp for motors, which covers the inflatable props that a lighting-only plug will not.
When a stake is the right shape
If your display has four or more runs that all need to be on at the same time, the stake removes the extension cord chain entirely. One schedule in the app governs the whole group, which is simpler than managing four separate timers.
It also suits displays that include inflatables and motorized props, which most lighting plugs exclude by design. Overload protection adds a layer of safety you do not get from a bare multi-tap.
Where it falls short
All six outlets switch as one group. There is no per-outlet control, so you cannot run the walkway on a sunset schedule and the animated inflatable on a later one from the same stake.
The 6-foot cord is short for a large property, the app is HBN-specific rather than tied to a major ecosystem, and setup needs a 2.4GHz network. For zone control, pair it with a dual-outlet plug instead of expecting the stake to do everything.
How to Choose a Smart Outlet for Holiday Lights
Most buyers spend their time on app features when the decision is really made by three physical questions: how exposed is the mounting point, how many amps is your display, and what is your router broadcasting.
What IP rating do you actually need?
IP44 means splash resistant, which covers a covered porch or an eave. IP64 adds protection against water jets and dust, which is the right choice for an exposed exterior wall in most of the country. IP66 handles heavy spray and is worth it in open, unsheltered positions.
A plug with no published rating is a plug we would not put outside. If the listing does not state one, assume it is an indoor device.
Wattage and amperage ceilings in plain numbers
A 15A household circuit is 1800W on continuous load. Most plugs here carry 15A/1875W per outlet, but the two dimmers are far lower: the KP405 handles 300W incandescent or 150W LED at a 4A ceiling, and the TREATLIFE caps at 400W incandescent or 150W LED.
Check the number on the cord tag for your strands, multiply by strand count, and compare. Do not use a dimmer on a load above its ceiling even if the app lets you try.
2.4GHz vs 5GHz Wi-Fi for a plug at the end of the yard
Every plug in this roundup is 2.4GHz only. That is deliberate on the manufacturers’ part, because 2.4GHz reaches further and penetrates masonry better than 5GHz, and an outdoor plug at the end of a property needs reach more than speed.
If your router only broadcasts 5GHz, split the bands or enable a combined network name before you buy. The Tapo P400M states the clearest figures: 300 ft in open space, 164 ft through three concrete walls.
Hub or no hub, and what Matter changes
Seven of these eight need no hub. They run on Wi-Fi and talk to Alexa, Google Assistant, or their own app, which is the simplest path for most households.
The exception worth understanding is HomeKit remote access on the meross plug, which requires an Apple home hub. Matter, on the Tapo P400M, is the broader answer: one device, every major platform, and less risk of being stranded when a brand changes direction.
How Many Lights Can You Run on One Smart Outlet?
Add up every strand before you buy, then compare against the plug’s ceiling rather than the circuit’s. A typical 40-strand LED set runs around 24W, so ten of them is roughly 240W, which is comfortable on any plug here. A set of large C9 incandescent bulbs can be four times that per strand.
The failed circuits we have seen are almost always one of two things: too many strands on a single dimmer, or a display split across outlets that share a circuit and push it past its limit when everything comes on at sunset.
To extend beyond one plug, split the display across two outdoor-rated plugs on separate circuits where possible, and stagger the on times by a few minutes so the two do not surge together. If you have a stake, the six outlets still share one switch, so the wattage ceiling still applies to the group as a whole.
Where to Put the Smart Outlet This Season
Never use an indoor smart plug outside. The reason people reach for one is that they have no exterior receptacle, and the correct answer is not an indoor plug with a lid.
Any exterior receptacle you use for a holiday display should be GFCI protected, with a weatherproof cover in place. That is a question that comes up constantly on electrician forums, and it is worth checking before you string any lights: an unfused indoor plug in the rain is the failure mode we would most want you to avoid.
If you have no exterior outlet, the sane options are to have an electrician install one, or to run an outdoor-rated extension cord from a GFCI receptacle indoors to a sheltered position near the display, with the smart plug mounted indoors or under cover. Home Assistant and HomeKit readers often run the cord but leave the adapter outside, which brings back the original problem.
One more practical note from our testing: the sockets on an IP64 plug have to face downward to keep water out of them. On a receptacle mounted high on a wall, plan the orientation before you force it.
How to Schedule Your Holiday Lights
Set the schedule once in October and stop thinking about it. Every app here supports recurring daily times, and most also support sunrise and sunset offsets that follow the shortening days through December automatically.
For a dusk-to-dawn schedule, turn on the offset option rather than entering a clock time. A display that comes on at 4:30pm in November and 5:15pm in December is the single best feature in this category, and it is the one people most often leave disabled.
For a holiday-only window, a Home Assistant user we came across was trying to figure out how to make a plug active only between December 1 and December 25 and had not found a template that made it click. The straightforward approach in any of these apps is a recurring schedule with a start and end date set to your holiday window, rather than a year-round routine you remember to cancel.
Use vacation or away mode if your display is visible from the street. It randomizes on and off times so the lights do not switch at the identical minute every evening, which is the pattern most often criticized by neighbors.
If you run no smart home setup at all, every plug on this list still works from its own app on your phone. That is the answer to the most common thread question on this topic: you do not need Alexa or Google to automate your Christmas lights.
What Real Users Complain About
The 2.4GHz-only limitation appears in the reviews of nearly every outdoor plug here, and it remains the most common reason a plug will not pair. Check your router before you buy, not after.
Dimmers draw the second most complaints, and the cause is almost always a load the dimmer cannot handle. Non-dimmable bulbs, smart bulbs, and transformers are named repeatedly as things that will not work through a plug-in dimmer.
App lock-in is the third theme. The Geeni, HBN, and meross units are each controlled through their own app, which is a real risk for hardware you intend to keep for five or six holiday seasons.
Finally, reviewers of the multi-outlet stake mention the remote and photocell variants as less dependable than the app-controlled version. Buy the Wi-Fi model, not the one with a handheld remote.
Frequently Asked Questions
Can I use a smart plug for Christmas lights?
Yes, and it is one of the strongest use cases for the category. Use an outdoor-rated plug with a published IP rating, plug it into a GFCI-protected receptacle, and keep your total load under the plug’s wattage ceiling. Most plugs here handle 15A/1875W per outlet, while plug-in dimmers handle far less.
Which smart plug is the best for controlling outdoor lights?
For most outdoor displays the Kasa Outdoor Smart Plug EP40 is the strongest all-round choice: an IP64 rating, two independently controlled outlets rated 15A/1875W each, sunrise and sunset scheduling, and no hub required. If your strings are dimmable and you need brightness control, the TREATLIFE dimmer is the alternative.
Is there a smart plug that can dim lights?
Most smart plugs only switch on and off, but a small group dims dimmable bulbs. The Kasa Outdoor Smart Dimmer KP405 is rated IP64 and handles 300W incandescent or 150W LED at a 4A ceiling. The TREATLIFE dimmer handles 400W incandescent or 150W LED but carries a lower IP44 weather rating.
Do smart plugs increase the electricity bill?
No. The plug draws negligible standby power, and it does not add consumption to the bulbs it controls. What it does is make a display easier to leave running, so the bill depends on your schedule. Use sunrise and sunset offsets and a bedtime cutoff so the lights are not on through the afternoon.
What are the disadvantages of smart plugs?
Most models only switch on and off rather than dimming. They need a 2.4GHz Wi-Fi network, and many are controlled through one vendor app rather than a shared standard. Outdoor models are only safe outside if they carry a published IP rating. Dimmers cap well below a full circuit, and a plug with no hub still needs a phone and Wi-Fi to set up.
Final Verdict for 2026
The Kasa Outdoor Smart Plug EP40 is the best smart outlet for holiday lights for the simple reason that nothing else on this list combines two independently switched outlets, a full 15A rating per socket, an IP64 rating, and a review history spanning many seasons. It is the plug we would put on our own house.
Add dimming with the TREATLIFE or Kasa KP405, add Matter and Apple Home with the Tapo P400M, and add reach with the HBN stake. Whichever you pick, check the wattage, check the IP rating, and set a sunset schedule once.
If you are still planning the rest of the season, our holiday movie ranking covers the other end of the evening.
