Description
Smart Control for Two Circuits in One Compact Zigbee Module
Transform your existing 2-gang wall switch into a powerful smart home controller with the Sonoff MINI DUO 2-Gang Zigbee Smart Switch (MINI-ZB2GS). This compact Zigbee 3.0 dual-channel relay fits discreetly behind compatible wall switches, allowing you to independently control two separate lighting circuits or appliances without replacing your existing switch plates.
Whether you’re upgrading a living room, bedroom, office, or any space with two controlled circuits, the MINI-ZB2GS combines reliable Zigbee connectivity, advanced automation features, and broad smart home compatibility in one space-saving device.
Independent Dual-Channel Control
Control two separate electrical loads using a single compact module.
Perfect for:
- Two lighting circuits
- Light and extractor fan combinations
- Light and bathroom fan
- Outdoor lighting
- Garage lighting
- Two independent appliances
- Smart home retrofits
Each relay can be controlled independently through your smart home platform or connected wall switches.
Supporting up to 10A per channel and 16A total resistive load, the MINI-ZB2GS is suitable for a wide range of residential lighting and switching applications.
Upgrade Existing Wall Switches
Keep the look of your existing switches while adding modern smart functionality.
The MINI-ZB2GS installs behind compatible wall switches, allowing you to continue using familiar switch plates while gaining:
- Remote control
- Voice control
- Timers and schedules
- Smart automations
- Scene control
- App-based management
A minimum wall box depth of approximately 60 mm is recommended for installation.
Detach Relay Mode
One of the standout features of the MINI-ZB2GS is Detach Relay Mode.
This advanced mode separates the physical wall switch from the relay output, allowing the switch to act purely as a smart scene trigger.
Ideal for:
- Smart bulbs that should remain permanently powered
- Home Assistant automations
- Zigbee scene controllers
- Multi-device routines
- Advanced lighting control
This provides significantly greater flexibility than a conventional smart relay.
Reliable Zigbee 3.0 Performance
The MINI-ZB2GS uses Zigbee 3.0, offering fast, dependable communication with low power consumption.
Benefits include:
- Instant local response
- Reliable communication
- Low network overhead
- Stable operation
- Self-healing Zigbee mesh networking
Unlike Wi-Fi devices, Zigbee products work together to create a resilient mesh network that becomes stronger as you add more powered devices.
Turbo Mode Mesh Extension
The MINI-ZB2GS also functions as a Zigbee router, helping to strengthen and extend your Zigbee network.
Turbo Mode helps:
- Increase wireless coverage
- Improve communication reliability
- Eliminate weak signal areas
- Support larger Zigbee installations
- Improve connectivity for battery-powered Zigbee devices
Every permanently powered MINI-ZB2GS contributes to a stronger, more reliable smart home.
Powerful Smart Home Automation
Create intelligent routines using your preferred Zigbee platform.
Example automations include:
- Turn on hallway lights at sunset
- Switch extractor fans off automatically after use
- Activate “Movie Mode” scenes
- Control two lighting zones independently
- Schedule outdoor lighting
- Trigger Home Assistant automations
- Coordinate lighting with occupancy sensors
The dual independent outputs provide far more flexibility than single-channel relays.
Broad Zigbee Compatibility
Compatible with most Zigbee 3.0 ecosystems.
Works with:
- Home Assistant (ZHA)
- Zigbee2MQTT
- SONOFF Zigbee Bridge
- OpenHAB
- Other Zigbee 3.0 compatible coordinators
A compatible Zigbee hub or coordinator is required.
Built for Safe & Reliable Operation
Designed for long-term reliability, the MINI-ZB2GS includes features such as:
- Overheat protection
- Surge protection
- Configurable power-on state
- High-quality relay components
- Stable Zigbee communication
These features help protect connected equipment while ensuring dependable everyday operation.
