Total Flexibility in an Ultra-Small Size
Meet the SONOFF MINI-ZBD Dry Contact smart switch. The ideal and safest solution for transforming garage doors, heating systems, and motors into smart devices running on the Zigbee 3.0 protocol.
Dry Contact Technology
It features a voltage-free relay, meaning it acts as a switch that opens or closes a circuit without sending current through it. This makes it completely safe for controlling electric garage door panels and alarm systems.
Dual Mode Support: NO and NC
It supports both Normally Open (NO) and Normally Closed (NC) modes, giving you absolute flexibility to integrate it with almost any mechanical or electrical system.
Dual Power Options (AC/DC)
The switch can be powered via standard household AC (100-240V AC) or DC (12-48V DC). Ideal for solar projects, boats, RVs, and low-voltage systems.
Built-in Zigbee Mesh Repeater
Not just for smart control, it functions as a Zigbee Router to boost network signal and extend its range to other devices in your smart home, ensuring high stability.
Direct Control of Small Motors
It can directly power small DC loads (up to 8W), such as solenoid valves in smart irrigation systems or small mechanical motors.
Home Assistant Compatibility
Powered by the high-efficiency EFR32MG21 chip, it offers perfect local compatibility with Home Assistant systems via ZHA or Zigbee2MQTT add-ons, in addition to supporting Alexa and Google Home apps.

Usage Scenarios and Installation Notes
- Requires a Smart Hub: Since it operates on the Zigbee protocol, this product must be linked to a Zigbee Hub/Gateway, such as the SONOFF ZBBridge, or used with Home Assistant for internet connectivity.
- Garage Doors and Gates: The most prominent use for this device; connect it to the wall button input of your garage motor to turn it into a fully smart garage.
- Inching Mode: Perfect for garage doors; you can set the device to perform an automatic turn-off (Auto-off) one second after switching on, simulating a normal button press.
- Heating Systems (Boilers) Control: Replace the traditional thermostat connection with this device to remotely schedule heating times and save energy.
- High Loads: Do not connect devices with high current draw (such as water heaters) directly to the output of this device. If you need to control a high load, use this device to trigger an external "Contactor," which will handle the high load.
