Best Smart Plugs for Christmas Lights (2026)

Quick answer: The Kasa Outdoor Smart Plug EP40A (~$17.30) 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 just want a cheaper way to schedule one outdoor outlet, the Kasa KP401 (~$12.02) does the same weatherproofing for 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 (~$27.99) 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.

1. Kasa Outdoor Smart Plug EP40A — Works With Everything (Our Pick)

Kasa EP40A — the only plug here that talks to Alexa, Google Home and Apple HomeKit at once. Image: TP-Link.

Around $17.30 (September 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 shows up in the Kasa app within a couple of minutes.

2. Kasa Outdoor Smart Plug KP401 — Best If You Just Want Scheduling

Kasa KP401 — same IP64 weatherproofing as the EP40A, single outlet, lower price. Image: TP-Link.

Around $12.02 (September 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 several 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?

GHome's outdoor plug — same IP64 rating as the Kasa picks, priced higher. Image: GHome.

Around $22.99 (September 2026) · 2 outlets, IP64, 15A/1800W per outlet · 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 it currently costs a few dollars 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

Govee's 4-pack — four separately switched indoor outlets, no weatherproof rating. Image: Govee.

Around $27.99 for 4 (September 2026) · Indoor use only · 15A/120V · 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 $7 each, each one controlled individually or grouped into a single scene from the Govee Home app, works with Alexa and Google Home, and rated for 15A so a coffee maker or space heater on the same circuit isn't a problem either.

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 — Cheapest Way to Automate Four Outlets

Amazon Basics 4-pack — cheapest per-plug price here, Alexa-only. Image: Amazon.

Around $23.00 for 4 (September 2026) · Indoor use only · Alexa only · No hub required

The lowest per-plug price in this guide, 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 the lowest price per plug here. If you're on Google Home or want app-based scheduling independent of a voice assistant, spend the extra few dollars 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.

The 5 Smart Plugs Side by Side

*Reference prices at the time of writing; check live listings — Amazon prices change frequently, especially around Prime shopping events in October.

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.

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 $12–17 plug, but it replaces buying both the lights and the automation separately.
