Sonoff ZBMini 2CH Duo

SONOFF MINI DUO 2-Gang Zigbee Smart Switch | MINI-ZB2GS – Ultra-Compact Dual-Channel Zigbee 3.0 Relay Module for Smart Home Automation
Transform your traditional wall switches into a powerful smart lighting system with the SONOFF MINI DUO (MINI-ZB2GS). This ultra-compact 2-gang Zigbee smart switch module lets you independently control two separate loads (lights, fans, or appliances) from one small device that fits neatly behind your existing switches – no need to replace your wall plates.
Key Features & Benefits
Dual Independent Control: Manage two circuits separately with up to 10A per gang (total 16A max resistive load). Perfect for controlling two lights, a light + fan, or any dual-load setup.
Zigbee 3.0 with Router Function: Reliable, low-latency connectivity and acts as a Zigbee signal booster (with Turbo mode) to extend your mesh network coverage for a more stable smart home.
Works with Existing Switches: Connects to standard rocker or push-button wall switches. Supports Detach Relay Mode – use your physical switches purely as smart triggers for scenes and automations while controlling smart bulbs directly.
Voice & App Control: Pair with a Zigbee gateway (SONOFF ZBBridge, iHost, etc.) for full control via eWeLink app, timers, schedules, and scenes. Compatible with Alexa, Google Home, and more through your hub. Local control works even without internet.
Advanced Automation: Power-on behavior (last state / on / off), stepper function for multi-scene control with one button, group control, and seamless integration with open-source platforms like Home Assistant (via Zigbee2MQTT).
Ultra-Compact & Safe: Measures just 45 × 39.4 × 16.8 mm – fits most standard junction boxes (minimum 60mm depth recommended). Built-in overload, overheat, and surge protection. Neutral wire required.
