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

Sonoff MINI-ZB2GS-L is the ideal automation solution for homes with classic electrical installations, where the neutral wire is not available in the switch wall box. Based on the Zigbee 3.0protocol, this miniature relay with two independent channels allows a traditional switch (single or double) to be turned into a smart one, without costly changes to the wiring. Its smart design eliminates the need for a capacitor (Anti-flicker module) in most cases, offering a clean and quick installation.

Main advantages

• No-neutral installation: It is specially designed to work using only the live wire. This makes it compatible with almost any old or new electrical installation, saving time and money on installation.

• Miniature dimensions: With an extremely small footprint, this relay fits easily into any wall box, even the most crowded ones, leaving enough space for the physical switch mechanism.

• Zigbee 3.0 Protocol: Provides a stable, secure connection and extremely low power consumption. As a Zigbee device, it does not use the Wi-Fi router's bandwidth and responds instantly to commands.

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

• Compatible with External Switches: Can be connected to rocker switches or momentary push buttons, allowing dual control (smart and manual).

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

Examples of Smart Automations

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

2. The „Leaving Home” Scene: Set up the system so that, with a single press of a smart button by the exit, all MINI-ZB2GS-L relays switch off the lights throughout the house.

3. Synchronisation with Motion Sensors: Set the hallway light to switch on automatically when the SNZB-03P sensor detects presence, even if the wall switch has been left in the „Off” position.

Package contents: 1 x Sonoff MINI-ZB2GS-L relay, mounting accessories, user manual. (Note: A Zigbee 3.0 Gateway is required for operation.)
