Kasa Smart Wi-Fi Power Strip, 6 Outlets (HS300)

Compatibility

? Inconclusive means we researched that ecosystem and the evidence doesn’t settle it — the catch says why, and the sources are listed below. 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.

Protocols: WIFI^[1]

What it can do^[1]

• Home Assistant: Per-outlet (child plug) energy state refreshes only every 60 seconds, per Home Assistant's integration documentation.
• Alexa: On/off and scheduling per outlet; TP-Link documents no path for energy readings to reach Alexa.
• Google Home: On/off and scheduling per outlet; no documented path for energy readings into Google Home.

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[1]

✓ Works without a subscription: Yes.

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

No plan or paid tier is named on either TP-Link product page for this model, including for the energy-monitoring and scheduling features that would be the obvious things to gate. Recorded as none on the absence of paywall language across two TP-Link pages rather than an explicit 'no subscription' statement. A TP-Link account is required to use the Kasa app; that is not a paid subscription, but it is an account you cannot skip.

Maintenance reality^[1][3]

• Works without the internet: Partly — some of it keeps working and some of it does not. See the detail below.^[5]
• Six individually controlled AC outlets plus three USB charging ports (5V/2.4A each, 5V/4A total across all three). Electrical: input 100–125 V~ 60 Hz 15 A; maximum load 15 A / 1875 W in TOTAL across all six outlets — a shared budget, not per outlet — with a 1/6 HP motor limit. Surge protection is rated '500V(L-N) 500V(L-G) 500V(N-G) Type 3 SPD'. Radio: IEEE 802.11b/g/n, 2.4 GHz only. Per-outlet energy monitoring: TP-Link's wording is 'Monitor how much energy devices connected to the power strip consume'. Dimensions 14.17 × 2.49 × 1.48 in (1.55 lb) in a low-profile body TP-Link describes as fitting 'behind furniture and in tight spaces'. App requires iOS 10 or Android 5.0 or higher. Warranty: '2-year limited warranty (US only)'.
• 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.^[8][12]

The catch

Per-outlet switching and per-outlet energy monitoring in one strip is the reason to buy it, and the ecosystem story is the reason to think twice: this is Wi-Fi and cloud only. No Matter, no Thread, no HomeKit — Apple Home households have no route at all, and Alexa and Google both run through TP-Link's cloud, so an internet outage or a service change takes remote and voice control with it. Home Assistant is the exception and controls it locally, but even that path now wants your TP-Link cloud credentials to authenticate locally, and some firmware makes you switch on third-party access in the Kasa app first. Watch the shared power budget: 1875 W and 15 A are the totals across all six outlets together, with a 1/6 HP motor ceiling — not a per-outlet allowance. One dating clue about how long this model has been around: the older hardware page TP-Link still publishes lists Microsoft Cortana among its voice assistants, a service Microsoft discontinued, while the current page lists only Alexa and Google Assistant. A second clue carries more weight, and TP-Link's own two surfaces disagree about it. The company's published US end-of-sale list for smart home names this strip at every hardware version with an end-of-sale date of 5 January 2026, a date already eight months past, while the Kasa store still lists it with a working buy button and no discontinuation notice. We record both rather than pick the flattering one. What it means for you is narrower than it sounds: 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 model as unsettled rather than expired.

Who it's for

A fit for an Alexa or Google household that wants six separately switchable outlets and wants to see which plugged-in device is actually drawing power — a desk, a media stack, or a garage bench where the point is finding the load rather than just switching it. It is also a good Home Assistant target, since HA polls it locally. Look elsewhere if you run Apple Home, if you need control that survives an internet outage without Home Assistant, if you want Matter, or if your loads together approach 1875 W or include a motor above 1/6 HP.

Its support-period rule is stated verbatim: "TP-Link will provide security updates for our products during the pre-defined support period. The defined support period will end 3 years after the product's end-of-life date." The document then carries a per-model table — Product/Model Name, Model Number, Defined Support Period — with real dates (e.g. "20/2/2029", "11/7/2027", "31/12/2029 or later*") given SEPARATELY FOR EACH HARDWARE VERSION. TP-Link's own end-of-life FAQ (tp-link.com/uk/support/faq/3562/), read the same day, defines EOL as production having "ended on the model or the specific version of the model" and lists Home Networking and Business Networking products only — no Kasa or Tapo smart-home models appear in it.
