EIGHTREE Smart Plug
Score: 77/100Rankings

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 Eightree Smart Plug offers high-power capacity and built-in energy monitoring in a compact, flame-retardant design, with easy Alexa and Google Assistant voice control. Its drawbacks include 2.4 GHz-only Wi-Fi, optional Zigbee that needs a hub, and a basic user interface. It suits budget-focused users who want energy-tracking for high-load devices.
