Leviton Decora Smart Switch Z-Wave 800 Series - Reliable Z-Wave

In this review the Leviton Decora Smart Switch Z-Wave 800 Series is evaluated for homeowners who want a dependable in-wall switch that joins a Z-Wave smart home with minimal fuss. The bottom line: it is best for users with a compatible Z-Wave hub who need remote access, voice commands, and scheduling for lights and small motors, because it combines straightforward installation with robust 800 Series features such as S2 security, SmartStart enrollment, and mesh repeating capability.

Key Features

• Z-Wave Plus 800 Series: Provides improved reliability and performance, including SmartStart enrollment and Over-the-Air Updates for future enhancements.
• Remote access and scheduling: When added to a compatible Z-Wave hub, it enables app control, timed schedules and the ability to turn exterior lights on at sunset.
• Voice command support: Works via a certified Z-Wave hub to accept voice commands for convenient hands-free control.
• High load capacity: Handles up to 15A and 3/4 HP so it can switch lights, ceiling fans, exhaust fans, motors and pumps.
• Repeater function: Acts as a Z-Wave repeater to strengthen mesh network reliability and extend range.
• 3-way compatibility: Can be used in single-pole or 3-way installations and pairs with a wired companion switch for multi-location control.

Who It's For

The Decora Smart Switch is ideal for homeowners and installers who already use or plan to use a Z-Wave hub and want a Decora-style in-wall device that blends with standard wiring and faceplates. It suits rooms where centralized scheduling, remote control, or voice activation will be used often, and where network range benefits from extra repeating nodes.

It is not aimed at buyers who need built-in Wi-Fi control without a hub, users who require double-tap scene triggers on the switch itself, or those who want a different aesthetic than Decora-style devices. Shoppers seeking an all-in-one ecosystem without a Z-Wave controller should look elsewhere.

Pros & Cons

Pros

• Reliable Z-Wave Plus 800 Series feature set improves security and allows OTA updates.
• Supports remote access, voice control and scheduling through a compatible hub.
• Acts as a repeater to increase the resilience of a Z-Wave mesh network.
• High load rating makes it suitable for lights and small motors.

Cons

• Requires a compatible Z-Wave hub for smart features, so it is not plug-and-play standalone smart Wi-Fi.
• Some users report mixed experience on advanced input functions such as frequency or double-tap behavior.

Specifications

Our Verdict

The Leviton Decora Smart Switch Z-Wave 800 Series is a practical choice for anyone with a Z-Wave hub who wants dependable in-wall control, scheduling and voice features with the added benefit of strengthening the Z-Wave mesh. It is good value for those who need higher load capacity and future-proofing through S2 security and OTA updates, but it is not the right pick if you do not plan to use a Z-Wave controller.
