Sonoff MINI-ZB2GS-L - Mini Zigbee 3.0 Smart Relay, No Null Wire, Ultra-Compact Design

The Sonoff MINI-ZB2GS-L is the ideal automation solution for homes with traditional electrical installations, where the Null (Neutral) wire is not available in the switch box. Based on the Zigbee 3.0 protocol, this miniature sized "Extreme" relay allows any traditional switch to be transformed into a smart switch without the need for costly wiring modifications. Its clever design eliminates the need for a capacitor (Anti-flicker module) in most cases, providing a clean and quick installation.

Key Selling Points

• No Neutral Required Installation: It is specifically designed to operate using only the neutral wire. This makes it compatible with almost any old or new wiring, saving time and money on installation.

• "Extreme" Miniature "Extreme" Size: With an extremely small footprint, this relay fits seamlessly into any wall nozzle, even the most cluttered, leaving plenty of room for the physical switch mechanism.

• Zigbee 3.0 Protocol: Offers a stable, secure connection and extremely low power consumption. As a Zigbee device, it doesn't take up Wi-Fi router bandwidth and responds instantly to commands.

• No Anti-Flicker mode required: Advanced energy extraction technology allows LED bulbs to operate (above a certain minimum power) without flickering, eliminating the need for an external bypass in most configurations.

• Compatibility with External Circuit Breakers: Can be connected to rocker (rocker) or return (push button) switches, allowing dual control (smart and manual).

• Certified Safety: Constructed of high quality flame retardant materials and equipped with advanced electronic protections, the MINI-ZB2GS-L ensures long term safe use inside walls.

Smart Automation Examples

1. Living Room Lighting Upgrade: Turn the classic chandelier into a smart light source that can be programmed to automatically switch off at 23:00 or be controlled by voice command (Alexa/Google Home).

2. Leave Home Scenario: Set the system so that at the press of a single smart button at the exit, all MINI-ZB2GS-L relays switch off the lights throughout the house.

3. Motion Sensor Synchronisation: Configures the hallway light to automatically turn on when the SNZB-03P sensor detects presence, even if the wall switch has been left in the "Off" position.
