SONOFF Zigbee Smart Light Switch No Neutral - Compact 4 Pack

Our review of the SONOFF Zigbee Smart Light Switch finds it best suited to homeowners and DIY installers who want a compact, no-neutral solution that fits behind existing rocker or self-reset switches. The single biggest reason to buy is its small size and straightforward integration with Zigbee hubs, which makes it an unobtrusive upgrade for smart homes that use Alexa, Google Home or SmartThings. Installation is frequently described as simple by customers, and the module's design is explicitly intended to fit inside the smallest 120 type wall switch boxes without requiring a neutral wire.

Key Features

• Compact Design: The small module is designed to fit inside the smallest 120 type wall switch box so it can be hidden behind existing switches.
• No Neutral Required: Works without a neutral wire, making it useful for older homes where neutral is not available at the switch.
• Zigbee Connectivity: Requires a Zigbee hub and integrates with common ecosystems for voice control through Alexa, Google Home and SmartThings.
• Two-Way Compatibility: Suitable for external rocker switches and self-reset switches so it adapts to typical wall switch types.
• Pack of Four: Sold as a 4 pack, which is convenient for upgrading multiple switches in a room or home without buying units individually.

Who It's For

The SONOFF Zigbee smart switch is ideal for DIYers, renters with access to change wall modules, and smart-home enthusiasts who already use a Zigbee hub or Home Assistant. Its compact size and no-neutral design make it particularly attractive for older homes and retrofit projects where space and wiring options are limited.

It may be less suitable for users who do not have a Zigbee hub or who need an out-of-the-box Wi-Fi solution without additional hardware. Also, anyone who requires advanced dimming features or proprietary ecosystems beyond Zigbee should consider other specialized devices.
