Best Smart Plugs for Christmas Lights (2026)
Quick answer: The Kasa Outdoor Smart Plug EP40A (~$19.99, checked Sept 25, 2026) is the best all-around pick for outdoor Christmas lights — it's IP64 weather-resistant, has two independently controlled outlets, and is the only plug here that works with Alexa, Google Home and Apple HomeKit without a hub. If you only need to schedule one outdoor outlet, the Kasa KP401 (~$16.99 on Sept 25) does the same weatherproofing for a few dollars less, minus HomeKit. If you're lighting an indoor tree or window display with several separate strings, a 4-pack like the Govee Smart Plug 4-Pack (~$31.99 on Sept 25) gets you four independently switched outlets for less per plug — just keep those indoors, since neither 4-pack in this guide carries a weatherproof rating. Whatever you buy, it still needs to go into a GFCI-protected outlet outdoors — a smart plug's weather resistance and a GFCI's shock protection are two different jobs, and outdoor holiday lighting needs both.
Every year it's the same routine: dig out the timer from a drawer, set it wrong, watch the lights come on at 2 p.m. instead of dusk, and eventually give up and just flip the porch switch by hand every night until January. A smart plug fixes that specific annoyance for about the price of a fast-food meal — set a schedule once in an app, or just tell Alexa to turn the display off from the couch, and it runs itself for the rest of the season.
The catch is that "smart plug" covers two very different products. Some are built and rated for sitting on an exterior wall through rain and snow; others are indoor multi-packs meant for a lamp or a coffee maker, with zero weatherproofing. Mixing the two up is the actual safety issue with holiday lighting — not the "smart" part. Below are five plugs we checked against official specs and live Amazon stock this week, sorted by what they're actually built for.
- Best overall (outdoor): Kasa EP40A (~$19.99 on Sept 25) — IP64, 2 outlets, Alexa + Google + HomeKit
- Single-outlet option (outdoor): Kasa KP401 (~$16.99 on Sept 25) — IP64, single outlet, built-in schedule/timer
- Alt brand (outdoor): GHome Smart Outdoor Plug (~$20.99 on Sept 25) — IP64, 2 outlets, costs more than the Kasa picks
- Best for multiple indoor zones: Govee Smart Plug 4-Pack (~$31.99 on Sept 25) — 4 outlets, indoor use only
- Lower-priced indoor 4-pack (Alexa only): Amazon Basics 4-Pack (~$25.99 on Sept 25) — 4 outlets, indoor use only. A Kasa 4-pack was lower per outlet that day; see how many smart plugs you need.
1. Kasa Outdoor Smart Plug EP40A — Works With Everything (Our Pick)

Around $19.99 (checked Sept 25, 2026) · 2 outlets, IP64 · No hub required
This is the plug we feature as our top pick, and it's still the easiest recommendation in this whole category. Two grounded outlets, controlled independently, so one side can run your porch string and the other a wreath or inflatable on its own schedule. The IP64 rating and hinged weatherproof cover mean it's rated to sit outside through rain and snow, and TP-Link's own instructions call out mounting it socket-down with the cover closed on anything you're not using — the actual failure mode for outdoor plugs is usually water pooling in an open socket, not the electronics themselves.
What sets it apart from every other plug on this page: it's Apple HomeKit-certified in addition to Alexa and Google Home. If your household mixes iPhones and Android phones, or you already run HomeKit automations for other outdoor gear, this is the one plug that doesn't force a compromise. Setup skips a separate hub — it joins your 2.4GHz Wi-Fi directly, and (per TP-Link's own product page) shows up in the Kasa app without extra pairing steps.
2. Kasa Outdoor Smart Plug KP401 — Best If You Just Want Scheduling

Around $16.99 (checked Sept 25, 2026) · 1 outlet, IP64, 15A/1875W · No hub required
If you don't need two independently switched outlets or Apple HomeKit, the KP401 gets you the same IP64 weather resistance and the same Kasa app for a few dollars less. It leans into scheduling specifically — beyond a basic on/off timer, it supports a sunset/sunrise offset, so you can tell it "20 minutes after sunset" once at the start of the season and never touch it again as the days get shorter through December.
It works with Alexa, Google Home and Samsung SmartThings, just not Apple HomeKit — the one feature that's exclusive to the EP40A above. For a single outdoor outlet doing one job (one light string, one inflatable, one string of icicle lights), that trade is an easy way to save a few dollars without giving up weatherproofing.
3. GHome Smart Outdoor Smart Plug — Worth It Over the Kasa Picks?

Around $20.99 (checked Sept 25, 2026) · 2 outlets, IP64, 15A/1800W per the listing · No hub required
Honest answer: for most people, no. GHome's outdoor plug hits the same IP64 rating, the same two-independent-outlet layout and the same voice/app control as the Kasa EP40A, but on Sept 25 it cost about a dollar more and works with Alexa and Google Home only — no Apple HomeKit. We're including it because it's a legitimate second brand with the same core spec sheet, which matters the one week a year the Kasa plugs sell out during a holiday-shopping rush. If EP40A stock is gone at checkout, this is a reasonable same-spec swap rather than a downgrade.
One detail worth knowing from GHome's own listing: it explicitly calls out landscape lighting, pool pumps and holiday lights as intended uses, and like the Kasa plugs it wants to be mounted vertically with the cover closed over anything not plugged in — the same rule, different brand.
4. Govee Smart Plug 4-Pack — Best for Several Indoor Zones

Around $31.99 for 4 (checked Sept 25, 2026) · Indoor use only · 15A/120V per the listing · No hub required
This is the pick once your Christmas lighting moves indoors — a tree, a mantel, a window display, a few strings that all need to come on together at dusk and off at bedtime. Four plugs at roughly $8 each, each one controlled individually or grouped into a single scene from the Govee Home app, and it works with Alexa and Google Home. The listing rates each plug at 15A/120V without giving a watt figure, which is plenty for light strings. For anything power-hungry, check the device's label and what else shares that circuit first, because a plug's rating doesn't add capacity to the circuit.
Important: neither this listing's title nor its official feature list mentions an IP rating or outdoor use — it's built like a standard indoor smart plug, with no weatherproof cover. Don't put this one outside. It's the right tool for four indoor decorations you want to control as a group, not a budget substitute for the outdoor-rated plugs above.
5. Amazon Basics Smart Plug 4-Pack — A Lower-Priced, Alexa-Only Option

Around $25.99 for 4 (checked Sept 25, 2026) · Indoor use only · Alexa only · No hub required
The lower per-plug price of the two 4-packs in this guide (though a Kasa 4-pack was lower per outlet on Sept 25, as our plug-count guide shows), and the catch is right there in the product title: works with Alexa only. No Google Home, no Apple HomeKit, no third-party app schedule beyond Alexa routines. If your house already runs on an Echo and you just need four indoor outlets on a timer for tree lights and a few decorations, that's a fine trade for a lower price per plug than the Govee pack. If you're on Google Home or want app-based scheduling independent of a voice assistant, spend a bit more on the Govee 4-pack instead.
Same rule as the Govee pack applies: this is a compact indoor design with no IP rating and no weatherproof cover in its listing. Indoor Christmas tree and window displays only — pair it with a GFCI-protected indoor outlet like any other plugged-in decoration, and use one of the three outdoor-rated plugs above for anything going outside.

Do I Need a GFCI Outlet for Outdoor Christmas Lights?
Yes — an outdoor smart plug is not a substitute for GFCI protection, and you want both. The Electrical Safety Foundation International specifically recommends plugging outdoor electric decorations into circuits protected by a ground fault circuit interrupter, precisely because outdoor lighting sits exposed to rain, snow and the standing water that follows.1 U.S. electrical code separately requires GFCI protection on dwelling-unit outdoor receptacles year-round, holiday season or not — the NFPA's own guidance points to the same rule.2
These are two different safety systems doing two different jobs. A GFCI outlet — built into the receptacle itself or a portable in-line adapter — watches for a current imbalance (the kind moisture or a damaged cord can cause) and cuts power in a fraction of a second to prevent a shock. An IP64-rated smart plug just keeps water out of the connection in the first place. One protects the person; the other protects the electronics. If your exterior outlet doesn't already have a GFCI (look for the "TEST"/"RESET" buttons on the outlet face), ESFI notes that portable outdoor GFCI adapters are sold anywhere electrical supplies are sold and don't require an electrician to install.1
What Does IP64 Actually Mean (and Why It Matters in Winter)?
IP ratings are read as two digits: the first is solid-particle protection (dust, dirt), the second is water protection. IP64 breaks down as a 6 — fully dust-tight — and a 4 — protected against water splashed from any direction. In practice: rain blowing sideways, snow melting on the housing, and the general damp of a porch through December are exactly what it's rated for. What it's not rated for is submersion — don't mount one where it can sit in a puddle or get buried in a snowdrift, and keep the hinged weatherproof cover snapped shut over any socket you're not currently using. All three outdoor plugs in this guide, and every listing's own instructions, call out mounting the plug vertically with the cord routing downward so water runs off the housing instead of into it.
Do Smart Plugs Like These Need a Separate Hub?
No — none of the five plugs above need one. Each connects straight to your existing 2.4GHz home Wi-Fi and is controlled from a free phone app (Kasa, Govee Home, or the Alexa app for Amazon Basics), plus whichever voice assistant it supports. That's a meaningfully lower bar than Zigbee or Z-Wave smart plugs, which do need a separate hub or bridge box to talk to your phone. If you're just automating Christmas lights for one season, that's one less box to buy, set up, and eventually store in a drawer for eleven months. If a plug you're eyeing says "Matter" on the box, the hub rules change a little (Google Home, for one, asks for a Matter-enabled hub), and our Matter smart plug guide sorts out which plugs need what, with sources.
Or Skip the Plug Entirely: A Self-Contained Light Kit
If you're starting your outdoor lighting from zero — no existing string lights to automate — it's worth considering a kit that builds the app control into the lights themselves instead of adding a separate plug. The Smart C9 Christmas Outdoor String Lights (~$99.99) are 66 feet of app-controlled, music-syncing C9-style bulbs built specifically for outdoor holiday displays, with the scheduling and voice control already built in — no smart plug required on top. It's a bigger spend than a roughly $17–20 plug, but it replaces buying both the lights and the automation separately.
For app-controlled strings and permanent roofline kits from Govee, Twinkly and Philips Hue, our best smart Christmas lights guide compares them and works out what going permanent costs over five seasons.
Best Smart Plugs for Christmas Lights FAQ
What is the best smart plug for outdoor Christmas lights?
The Kasa Outdoor Smart Plug EP40A (around $20, checked Sept 25, 2026). It's IP64 weather-resistant, has two independently controlled outlets, and is the only plug in this guide that works with Alexa, Google Home and Apple HomeKit at once, so it fits whatever ecosystem your house already runs on.
Do smart plugs need to be plugged into a GFCI outlet outdoors?
Yes. ESFI recommends GFCI protection for any outdoor electric decoration, and U.S. code requires it on dwelling-unit outdoor receptacles regardless of season. A weatherproof smart plug and a GFCI outlet do two different jobs — you want both.
What does IP64 actually mean on an outdoor smart plug?
Fully dust-tight (the 6) and protected against water splashed from any direction (the 4). It's built for rain and snow, not submersion — keep the weatherproof cover closed over unused sockets.
Do these smart plugs need a hub to work?
No. All five connect directly to home Wi-Fi and are controlled from a free app plus Alexa or Google Home — no separate hub or bridge required.
Can I use an indoor smart plug outside for Christmas lights?
No, not safely. The Govee and Amazon Basics 4-packs in this guide have no IP rating or weatherproof cover. Use them for an indoor tree or window display, and use an IP64-rated plug like the Kasa EP40A, KP401 or GHome for anything outside.
Will a smart plug still work in freezing temperatures?
The IP64-rated outdoor plugs here are built for year-round outdoor mounting, including freezing nights. What usually fails in cold weather is the light string or extension cord — inspect cords for cracked insulation before each use.
