Product detailed description

🧠 Sonoff Mini DUO: Simplicity and intelligence in one!

MINI-ZB2GS is a compact and powerful 2-gang Zigbee smart switch designed to be installed in standard wall boxes with a minimum depth of 60 mm. This switch allows independent control of two devices with a total resistive load of up to 16 A (maximum 10 A per channel, resistive load), meaning you can easily automate two lights or appliances without replacing your existing switches.

Compatibility with Zigbee 3.0

Thanks to the standard Zigbee 3.0 protocol, it integrates seamlessly with third-party open-source platforms (e.g., Home Assistant – ZHA/Zigbee2MQTT), enabling cross-device automation and smart scene control.

It functions as a Zigbee router and features Turbo mode to enhance signal strength and expand network coverage for more stable device communication.

Smart Control

It transforms traditional switches into smart ones, supports app or voice control, and easily sets timers for smart and automated operation.

Ideal for retrofitting or smart upgrades when you want to discreetly control two circuits with an in-wall module — featuring quick installation and a reliable Zigbee connection.

Small and Safe

Its small form factor fits effortlessly behind wall switches, and its comprehensive safety features (such as overheat and overvoltage protection) ensure reliable operation during everyday use.

 

Simplify Everyday Situations

Works with Apple Home via Matter Bridge

All solutions integrate SONOFF Zigbee devices into your Apple ecosystem via the Matter Bridge, enabling seamless control of connected devices.

Compatible with Multiple Zigbee Hubs

Feature Overview

📝Note: Suboptimal performance may occur when adding this device directly via the Alexa gateway. For best results, we recommend adding the device to the eWeLink app via the SONOFF Zigbee gateway and then syncing it with Alexa via the cloud.

Main Advantages

🌐 Zigbee 3.0 Compatibility: Works with Zigbee 3.0 hubs and open-source platforms for interconnected automations and smart scenes.

🔌 Dual Load Control: Two separate channels (max. 10 A per branch, 16 A total for resistive load) for independent control of two circuits.

🔄 Connection with Classic Switches: Ability to connect existing wall switches to combine manual and smart control.

📡 Zigbee Signal Amplifier: Integrated Zigbee router with Turbo mode to strengthen and expand network coverage.

📱 App and Voice Control: Control via compatible Zigbee gateways and the eWeLink platform with voice assistant support.

⏱️ Advanced Automations: Timers, schedules, scenes, and adjustable behavior upon power restoration (last state, always on, always off).

🚦 Detach Relay Mode: A physical switch can act as a smart scene trigger without turning off the power to smart bulbs.

🌍 Local Control Without Internet: When connected to a Zigbee gateway, the device can be controlled locally even during an internet outage.

🔒 Small and Safe Design: Compact dimensions for easy installation, plus overheat and overvoltage protection for long-term reliability.
