Overview
The SONOFF MINI-ZBD is a small Zigbee module designed to automate boilers, pumps, electric gates and garage doors, among other equipment that expects a simple push-button signal. Its output is a potential-free dry contact, which means no voltage travels to the device it operates.
At 41 × 43 × 21.5 mm it fits tight control boxes. It runs from 100–240V AC or a 12–48V DC supply, which suits both mains installations and solar or battery systems.

What it does
Dry-Contact Relay: Supports normally open (NO) and normally closed (NC) switching, ideal for gates and garage doors
Flexible Power Input: Supports 100–240V AC or 12–48V DC.
Inching or pulse mode for motors that need a momentary contact
Zigbee Signal Repeater: Can help extend your Zigbee network when powered by AC.
Compatible with Home Assistant through ZHA or Zigbee2MQTT, and with eWeLink, SmartThings and Alexa via a hub
Suitable for low-power solenoid valves and DC motors rated up to 8W
