🎯 Smart Features You’ll Actually Use
Dual Independent Channels
Each channel operates independently — turn on the living room light while the fan stays off. 10A per gang, 16A total across both channels.
Zigbee Router + Turbo Mode
Every MINI-ZB2GS strengthens your Zigbee mesh network. Turbo mode boosts signal for more stable, wider-reaching device communication.
Detach Relay Mode
Separate physical switches from relay control. Use wall switches as smart scene triggers while keeping smart bulbs powered and online.
Stepper Function
One button, multiple scenes. Each press cycles through customisable actions for both channels — e.g. all on → channel 1 only → all off.
Schedules & Automations
Set timers, countdowns, and smart scenes via eWeLink or Home Assistant. Automate based on time, sensors, or other Zigbee devices.
Voice Control
Works with Alexa and Google Assistant via your Zigbee hub. Also supports Siri via Matter Bridge (ZBBridge-U/eWeLink CUBE).
🏡 Home Assistant Integration
🔗 Integration Methods
ZHA (Zigbee Home Automation) — built into Home Assistant, auto-discovery, both channels appear as separate entities.
Zigbee2MQTT — advanced features, MQTT broker, full configuration of both channels and Stepper function.
eWeLink app — pair via ZB Bridge-P for app and voice control, smart scenes, and scheduling.
