Kasa Outdoor Smart Plug
Score: 81/100Rankings

The Kasa Outdoor Smart Plug (KP401) provides weather-proof, dual-outlet control with a long 300 ft Wi-Fi range, making it ideal for garden lights, pumps and other outdoor devices. Its limitations include a 2.4 GHz-only connection, the need to cap unused sockets, and a relatively large size. It is best suited for homeowners who need reliable, voice-controlled outdoor power management.

The TP-Link Kasa HS105 is a compact, hub-free smart plug that offers reliable on/off control, scheduling and voice integration for up to 1800 W. It lacks energy monitoring and 5 GHz Wi-Fi support, and does not work with Apple HomeKit. Best suited for budget-conscious users who need basic control without extra features.
