The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Kasa KP401 is essentially the single-outlet, budget-tier sibling of the EP40, and reviewers treat it that way. PCMag's coverage of the broader Kasa outdoor line praises responsive app and Alexa control, and the 6,659 Amazon reviews at 4.5 stars echo that. At under $20 it is by some distance the cheapest expert-recommended outdoor smart plug in this roundup.
What reviewers liked
- Lowest price among expert-recommended outdoor smart plugs in our data
- pcmag.com's Kasa outdoor coverage describes responsive app and voice control
- IP64 weather resistance with attached cover when not in use
- 6,659 Amazon reviews at 4.5 stars corroborates a stable product
- r/TPLinkKasa owners report easy setup and reliable scheduling
Where it falls short
- Single outlet only — no independent dual scheduling like the EP40
- r/homeassistant high-trust thread cautions against Kasa for local-only smart-home setups
- No Matter support on this SKU
- Wi-Fi cloud dependency means features degrade during internet outages
- Occasional compatibility quirks with multi-mode holiday lights reported on r/TPLinkKasa
Across the reviewers we read, the Kasa KP401 is essentially the single-outlet, budget-tier sibling of the EP40, and reviewers treat it that way. PCMag's coverage of the broader Kasa outdoor line praises responsive app and Alexa control, and the 6,659 Amazon reviews at 4.5 stars echo that. At under $20 it is by some distance the cheapest expert-recommended outdoor smart plug in this roundup.
Walmart and Home Depot verified-purchase reviewers describe it as a no-fuss setup for shoppers who only need one outlet automated — porch lights, a single fountain, seasonal inflatables. r/HomeKit and r/TPLinkKasa owners in our data report stable scheduling and no recurring connectivity issues, with one r/TPLinkKasa thread noting compatibility with most standard holiday lighting (with the occasional edge-case multi-mode light requiring a workaround).
The caveat from r/homeassistant is the same one that applies to the EP40: a high-trust thread explicitly cautions Kasa shoppers about long-term cloud dependency and recommends Z-Wave or Zigbee alternatives for fully local control. For mainstream Alexa or Google Home shoppers who want the cheapest credible outdoor smart plug, the trust-weighted evidence still lands here.
- 【Long Wi-Fi Range and IP64】Long Wi-Fi range up to 300 feet with IP64 weather resistance. Waterproof cover is attached to protect it from dirt when not in use. Supports up to 15A/1875W.
- 【Voice and Remote Control】Add voice control to any outdoor outlet. Enjoy the hands-free convenience of controlling any outdoor electronic appliances with your voice via Alexa or Google Home Assistant. Turn electronics on and off from anywhere with your smartphone using the Kasa app, whether you are at home, in the office or on vacation.
- 【Easy Set Up and Use】2.4GHz Wi-Fi connection required. Plug in, open the Kasa app, follow the simple instructions and enjoy the wifi smart plug. For landscape lighting, swimming pool pumps, holiday lights, or other appliances.
- 【Scheduling】Use schedules or countdown timer to set your smart plug to automatically turn on and off at the time you want. Sunset/sunrise offset makes it even smarter to act according to the real daytime.
