Z-Wave Long Range S2 Dimmer Switch ZEN77 800LR - Reliable Z-Wave

Our review of the Z-Wave Long Range S2 Dimmer Switch ZEN77 800LR finds it best for homeowners and installers who want a reliable in-wall dimmer that integrates with a Z-Wave hub and existing non-dimming switches. The main reason to buy is straightforward: it provides wireless brightness control with the latest Z-Wave Long Range performance while simplifying 3-way and 4-way wiring because no auxiliary dimmers or special switches are needed. This review focuses on practical installation, everyday performance, and real-world limitations so readers know whether it fits their setup.

Key Features

• Wireless brightness control: Lets users turn lights on/off and dim via a Z-Wave hub for consistent remote control and automation when paired to a compatible controller.
• Z-Wave Long Range: Delivers greater range and faster signal speed for direct-to-hub communication if the hub supports Long Range, improving reliability in larger homes.
• Simple multiway wiring: Works with existing on/off switches in 3-way, 4-way, or 5-way setups without add-on dimmers, reducing installation time and avoiding rewiring other boxes.
• Compact depth: The 1.16' deep body fits shallow or crowded electrical boxes and eases fitting the switch where space is limited.
• Customizable behavior: Double-tap, adjustable multi-color LED indicator and programmable features give installers and advanced users flexibility through hub settings.
• Neutral required: Uses a neutral connection for stable operation, which enables consistent dimming performance with LED loads.

Who It's For

This dimmer is ideal for DIY homeowners, electricians, and smart home enthusiasts who already use a compatible Z-Wave hub such as Z-Box, SmartThings/Aeotec hub, Hubitat, or Home Assistant and want dependable Z-Wave control plus range improvements. It is particularly useful where existing multiway circuits use simple on/off switches and you want minimal changes to remote boxes.

It is not for people who need direct voice control from a smart speaker without a Z-Wave hub, or for applications like ceiling fans, motors, appliances, or chandeliers. Also check wiring: a neutral must be present in the box and loads must not exceed the specified wattages.

Pros & Cons

Pros

• Works well with hubs such as SmartThings and Hubitat and pairs without much fuss according to users.
• Ease of installation in multiway setups because no auxiliary dimmer is required in remote boxes.
• Good build quality and customization options for advanced users who want to tweak behavior via hub parameters.
• Acts as a Z-Wave repeater in mesh networks and supports a range test tool for troubleshooting connectivity.

Cons

• Requires a compatible Z-Wave hub for voice and remote control; it will not work directly with smart speakers.
• Maximum load limits are modest: do not exceed 100 W for LEDs and 300 W for incandescent bulbs, so it is not suitable for heavy loads or motors.
