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 HS110 smart plug offers 2.4 GHz Wi-Fi control, real-time energy monitoring and a slim stackable form factor. Its lack of 5 GHz Wi-Fi and a maximum 15 A load may restrict high-power devices. Best suited for energy-conscious homeowners who want detailed power insights and broad voice-assistant integration.
