Compatibility
| Ecosystem | Support | The catch |
|---|---|---|
| Amazon Alexa | WorksWorks with this ecosystem | Named by TP-Link on both the legacy and current product pages, and each of the six outlets appears as its own controllable device. The mechanism is the Kasa skill over TP-Link's cloud — there is no Matter and no local Alexa path — so voice and remote control depend on TP-Link's service and your internet connection. TP-Link documents no route by which the per-outlet energy readings surface in Alexa; that data lives in the Kasa app. |
| Google Home | WorksWorks with this ecosystem | Same standing as Alexa: named on TP-Link's own compatibility list, per-outlet control, cloud-to-cloud through the Kasa service with no local option and no Matter. Energy readings are not documented as reaching the Google Home app. |
| Apple Home | Doesn't workVerified: does not work with this ecosystem | A positively evidenced negative rather than an unchecked cell. Apple Home admits only HomeKit or Matter, and this model has neither: TP-Link's current Kasa page enumerates its voice support as 'Alexa and Google Assistant' with no mention of Apple, HomeKit, Siri or Matter anywhere, and the specification lists no Matter certification. With both protocol doors closed, there is no route regardless of vendor intent. Households that want an Apple-visible strip need a Matter model — TP-Link's own Tapo power strip line is where that appears, not here. |
| SmartThings | Not checkedWe have not verified this yet — this is not a claim about the product | TP-Link's compatibility list for this model names only Alexa and Google Assistant, and SmartThings appears on neither product page — but absence from a vendor list is not the same as a verified negative, and no SmartThings-side documentation was read this pass to settle it. Community SmartThings drivers for Kasa devices are known to exist and are not a vendor-supported path. Recorded unknown with the reason, rather than a `none` the evidence does not yet carry. |
| Home Assistant | WorksWorks with this ecosystem | The one ecosystem where this strip is NOT cloud-bound, and it is confirmed from Home Assistant's side rather than TP-Link's: Home Assistant's core TP-Link integration lists HS300 by name and 'connects locally to the devices without going via the TP-Link cloud'. Three caveats from the same documentation, all of which bite in practice: newer Kasa firmware requires your TP-Link cloud username and password to authenticate for LOCAL access; some firmware versions 'require explicit activation of third-party integrations' in the Kasa app before Home Assistant can connect at all; and for power strips specifically, 'the energy monitoring state of Kasa power strip child plugs is only updated every 60 seconds', so per-outlet energy readings lag by up to a minute rather than streaming live. |
? Not checked means we haven’t verified that ecosystem yet — it is a statement about our research, never a verdict on the product. A Setup Check can research it for you.
Protocols: WIFI
Subscription reality
✓ Works without a subscription: Yes.
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 `none` on the absence of paywall language across two first-party pages rather than on an explicit 'no subscription' statement. A TP-Link account is required to use the Kasa app, which is not a paid subscription but is an account dependency.
Maintenance reality
- Cloud dependence: Yes — a server shutdown would degrade or brick this device
- 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)'.
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.
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.
