Kasa Smart Outdoor Smart Plug KP400
Score: 81/100Rankings

The Kasa KP400 is a dual-outlet outdoor smart plug with an IP64 rating, long Wi-Fi range and voice-assistant integration for up to 1875 W of power. It does not provide energy monitoring and is limited to 2.4 GHz Wi-Fi, requiring a GFCI-protected outlet for safe outdoor use. Ideal for homeowners who want reliable remote control of moderate-power outdoor devices such as lights or holiday decorations.

The Leviton Decora Smart Plug-in (DZPA1-2BW) is a Z-Wave Plus plug-in offering high-capacity control up to 1800 W and built-in surge protection. Its main trade-off is the mandatory hub requirement and lack of dimming or outdoor rating. Best suited for homeowners with an existing Z-Wave hub who need reliable control of high-power indoor devices.

Products in the top-left offer the best value (high score, low price).

Professional reviewers and product listings position the DZPA1-2BW as a robust, high-capacity Z-Wave plug-in ideal for users already invested in Z-Wave ecosystems. They commend its load versatility, fast Z-Wave Plus communication, and surge protection, while noting the necessity of a hub and the absence of dimming as trade-offs.
No direct user reviews were found in the sources; product pages describe typical applications such as lamps, fans, and holiday lights and note that the hub requirement may frustrate users without a Z-Wave hub.
