Score: 79/100Rankings
The Kasa HS220P3 provides hub-free Wi-Fi dimming with on-device buttons and broad voice-assistant support. It requires a neutral wire and is limited to 2.4 GHz networks and single-pole setups. Best for DIY homeowners seeking an easy, affordable smart dimmer.
Leviton Decora Smart Wi-Fi Mini Plug-In Dimmer (DW3HL-1BW) adds wireless dimming to lamps via a compact outlet-plug design, supporting voice assistants and Matter after a firmware update. Its low load limits and need for optional companions for multi-location control restrict high-power applications. Best for renters or temporary lamp setups.

Professional reviewers emphasize the HS220P3's ease of installation thanks to the guided app setup, its ability to quickly set appropriate lighting for different occasions, and the convenience of built-in dimmer buttons. The lack of a required hub and broad voice-assistant support are also highlighted as strong points.
Everyday users commonly praise the remote control capability, voice-assistant integration, and tactile dimmer buttons on the switch. Positive remarks focus on the simplicity of setup and the flexibility of scheduling, while the main frustrations revolve around the need for a neutral wire and the limitation to 2.4 GHz Wi-Fi.
