Score: 79/100
Leviton Decora Smart Plug-in Outlet
Score: 80/100Rankings

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.

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.

Professional reviewers consider the HS105 a solid entry-level smart plug, emphasizing its space-saving form factor, easy installation, and dependable voice integration, while noting that power-monitoring enthusiasts will need to look at the HS110 or EP25 for those capabilities.
Customers generally express satisfaction with the plug's reliability, straightforward setup, and compactness, but many wish it included energy monitoring and broader Wi-Fi compatibility.



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.
