Its ultra-compact design ensures it fits into any mounting box, while the "Detach Relay" mode provides flexible control for smart lighting. With safety features like overheat protection and flame-retardant casing, it is an ideal choice for stable, dual-load smart home automation.
Overview:
The SONOFF MINI DUO 2-Gang Zigbee Smart Switch (MINI-ZB2GS) is an innovative smart device that enables independent control of two electrical loads from a single, compact unit. Utilizing the stable and efficient Zigbee 3.0 protocol, it integrates seamlessly with major smart home ecosystems including Amazon Alexa, Google Home, and Samsung SmartThings. The MINI-ZB2GS is designed to fit into a wide variety of mounting boxes, making it a perfect retrofit solution. Its "Detach Relay" mode allows users to keep smart bulbs connected to power while still using physical switches for control, and its robust build quality ensures long-term reliability for your home automation projects.
Features:
- 2-Gang Independent Control: Manage two lights or appliances independently from a single compact device (10A per gang, 16A total max load).
- Zigbee 3.0 Mesh Routing: Acts as a Zigbee router to extend and strengthen your smart home mesh network network. Features an advanced Turbo Mode to boost signal range.
- Ultra-Compact Footprint: Tiny form factor (only 45 x 39 x 18 mm) ensuring it fits comfortably behind existing dual-gang wall switch plates in standard mounting boxes.
- Detach Relay Mode: Separates the physical wall switch state from the internal relay control. Perfect for using physical wall switches as smart scene triggers while keeping smart bulbs fully powered and online.
- Advanced Stepper Function: Allows a single external button to cycle through multiple customized smart scenes for both connected channels.
- External Switch Support: Compatible with various manual switch configurations, including rocker switches and momentary push buttons (via S1 & S2 terminals).
- Configurable Power-On State: Choose whether the switch defaults to ON, OFF, or remembers its last state when home power returns after an outage or load shedding.
- Industrial Grade Safety: Constructed with built-in overheat protection and surge protection for safe, worry-free execution of heavy daily electrical loads.
