Kasa Smart Wi-Fi Outdoor Plug (EP40)

Compiled by SmartHomeWorkflow Research · Kasa · Plugs & Outlets · Price: No price established. TP-Link's own Kasa page for this model publishes the full specification and the compatibility statement but prints no price; when we read it on 2026-10-27, its Buy Now link led to an Amazon search rather than to a TP-Link store. No retailer figure was substituted.

⚠ Similar names, different products: TP-Link sells a second outdoor plug one letter away: the EP40M. The M is the version certified to the Matter standard, and that single letter decides whether the plug can join Apple Home or a Samsung SmartThings hub directly. This record is the plain EP40, which is not Matter certified. Check the letter on the box, not the picture.

Degraded affects IFTTT only, and the outdoor plug itself is unimpaired. Alexa, Google Home and Home Assistant are unaffected; the plug's own schedules and timers are untouched. What changed is that IFTTT, a third-party automation service, stopped working with this plug on 1 August 2026 by TP-Link's decision rather than by a fault. TP-Link points users to the Smart Action feature inside its own apps, which is a substitute within TP-Link rather than the cross-vendor link IFTTT provided. Checked by model string rather than by brand inference: 'EP40' appears on TP-Link's own affected-products list. TP-Link's product page announces no replacement, and the Matter-certified EP40M sits alongside it; the plug's end of sale is a separate fact, from TP-Link's US end-of-sale list (11 July 2024). Same subtractive shape already recorded on kasa-hs300-power-strip and tapo-p400m-outdoor-plug. TP-Link's US end-of-sale list for smart home gives this plug an end-of-sale date of 11 July 2024, so it is listed here as discontinued, even though the Kasa page still links to an Amazon search for it. The letter at the end of the model number is the whole decision. This is the EP40, and TP-Link also sells an EP40M — the M version is certified to the Matter standard and this one is not, which was confirmed against the certifying body's own registry with the M version present as a control. In practice that means this plug reaches Alexa and Google Assistant through TP-Link's service, and reaches Home Assistant on your own network, while TP-Link names no Apple Home route for it and there is no settled answer for Samsung SmartThings. Three smaller things. It joins only the slower 2.4 gigahertz band, so a network running 5 gigahertz alone will not take it. Its weather rating covers dust and splashing rather than standing water, and TP-Link says it must go into a receptacle with ground-fault protection outdoors. And there is no energy monitoring, so you cannot see what the outdoor lights are costing you. An end-of-sale date is not an end-of-support date, and TP-Link has not said whether the one starts the clock on the other, so treat the security-update horizon on this plug as unsettled rather than expired.

Before you buy

What do you need to make it work?

No hub and no bridge. What TP-Link does require is a secured wireless network on the slower 2.4 gigahertz band — the plug cannot join a 5 gigahertz network, and TP-Link states that plainly — plus the free Kasa Smart app and a Kasa account. TP-Link also states an electrical condition that is easy to skip and is about safety rather than convenience: outdoors or in a wet location the plug must go into a receptacle with ground-fault protection.[1][18][32]

One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

Setup and sources

Apple Home

Not confirmed either way. TP-Link names Alexa and Google Assistant for voice control on this plug's page and does not name Apple Home. The Matter ledger lists TP-Link's Matter version of this plug, the EP40M, and not the EP40, but the certification body's own product search no longer works as a second check, so we do not record a firm no. If Apple Home matters to you, the EP40M is the version TP-Link certified for Matter.^[2]

Google Home

Named by TP-Link on this model's own page alongside Alexa, and set up the same way by linking the two accounts. Same shape as Alexa: full control because on and off is all there is, and it depends on the internet because the link is made between TP-Link's service and Google's.^{[1][17][18][21][25][32][35][39]}

Alexa

TP-Link names Alexa on this model's own page, reached by linking your Kasa account to the Kasa skill. On and off is the whole job this plug does, so there is nothing missing from the voice control. Two limits worth knowing: each outlet shows up separately so you can name them, and the connection runs between TP-Link's service and Amazon's rather than across your own network, so voice control stops during an internet outage even though the plug itself keeps its schedule.^{[1][18][20][32][34]}

On/off: On and off and scheduling only. This model has no energy monitoring, so there is no energy data for any platform to show — that gap belongs to the plug, not to the platform.

SmartThings

TP-Link publishes no compatibility list for this plug — what its page carries is a voice-control feature blurb, 'Use simple voice commands with Alexa or Google Assistant to enjoy your hands free.' That names where voice works; it is not a statement about SmartThings in either direction, and TP-Link does name Samsung SmartThings on some other Kasa product pages. What is settled is that there is no standards route: the certification registry holds no Matter certificate for the EP40, though it does hold one for the EP40M, so any SmartThings support would have to be a connection TP-Link builds and maintains itself. Treat this as unanswered rather than as a no, and check TP-Link's current compatibility list before buying for a SmartThings home.^{[2][10][18][32]}

Home Assistant

The strongest answer on this record, and it rests on the model name rather than on a guess about the device class: Home Assistant's own TP-Link documentation lists EP40 explicitly among the devices it supports. Home Assistant states the integration talks to the plug on your own network rather than through TP-Link's service, which means it keeps working when the internet does not. The catch is the sign-in: Home Assistant also states that newer Kasa devices need your TP-Link account email and password to authenticate for that local access, so a local connection still begins with a vendor account.^{[4][12][13][26]}

It is a statement about the available evidence, never a verdict on the product. A Setup Check researches your exact setup where the official sources don’t answer.

Plans and ongoing costs^[1][18][32]

✓ Works without a subscription: Yes.

Vendor account required: Yes — you must create a vendor account to use it.^[1][18][32]

No plan, tier or premium feature appears anywhere on TP-Link's page for this model, and the app is named as free in the system requirements. The honest limit is that this is the absence of any paywall language on one product page rather than an explicit promise never to charge — including in the scheduling and away-mode sections, which are where a vendor would normally put a gate.

Maintenance and offline use

Works without the internet: Inconclusive — we read the vendor's own material and it does not answer this either way. It does not mean the product fails without the internet.
Two independently switched outlets on one weatherproof body, with a six-inch cable so it hangs clear of the receptacle. TP-Link's stated ratings: 15 amps maximum load in total, 1,875 watts, and a 1/2 horsepower motor rating, on 802.11b/g/n wireless at 2.4 gigahertz only. Weather rating is IP64, which covers dust and splashing water rather than immersion, and the stated operating range is -4 to 122 degrees Fahrenheit at 10 to 90 percent humidity without condensation. Body measures 4.3 by 1.5 by 3.2 inches. Listed approvals are RoHS, FCC, IC, ETL and the IP64 rating. The box holds the plug with its six-inch cable, one clamp and screw, and a quick start guide. There is no energy monitoring on this model — a real difference from TP-Link's own indoor EP25, which has it.
Security updates: Kasa states its security-update commitment for this model as a period rather than a date: ends 3 years after the product's end-of-life date (UK-declared — the maker's legal commitment is filed for the United Kingdom). That is a floor measured from a starting point the manufacturer sets — a launch or a purchase — rather than a fixed end date, so it cannot be placed on a calendar here. We record the commitment as the manufacturer states it, in our words, rather than converting it into a date it did not give. This is a published commitment, not a gap in our research.^{[5][27][28][40][41]}

Who it's for

TP-Link no longer sells this plug new in the US, so this profile mainly serves owners and anyone looking at remaining stock. A good fit for a household that wants two separately switched outdoor outlets on a timer or a voice command, already lives in Alexa or Google, and does not need to know how much power the load draws. Home Assistant owners get something the other platforms do not: Home Assistant talks to this plug on the home network rather than through TP-Link's service, so it keeps working in an internet outage. Look elsewhere if your home runs on Apple Home, where TP-Link names no route for this model and the EP40M is the version TP-Link certified for Matter; if Samsung SmartThings is the platform you need answered before you buy; if your wireless network runs only on the faster band; or if energy monitoring matters to you.

Numbered sources below back the facts marked with the matching number above. This is a research profile: compiled from manufacturer documentation, certification registries, and published testing — we state facts, not verdicts, and we have not physically tested this unit. How we work →

Where these facts come from

No mark: Everything on this page without a mark comes from the people answerable for it: the manufacturer, the platform's own documentation, or a certification register. That is the standard we hold ourselves to.
Seller's spec sheet: This fact comes from a retailer's or a reviewer's specification listing instead of from the manufacturer. A few compatibility answers still rest on one, and we are replacing those with the maker's own word as we find it. The date is when we last checked, because these listings change without notice.
Someone's observation: This fact comes from an owner, a forum, or a community project — someone with the product in front of them rather than the company that makes it. Worth knowing, and not the same as the maker saying so.

Below is every source behind the facts on this page, numbered so you can trace any one of them. Each is quoted in the source's own words, with the date we last read it — we keep the wording exact rather than tidying it, so you can check what was actually said.
