Sonoff MINI-D Zigbee Smart Switch (Gate Garage Smart Switch)

SONOFF MINI Dry Zigbee Dry Contact Smart Switch (MINI-ZBD)

Automate garage doors, electric gates, boilers, pumps and other dry-contact devices with the compact and versatile SONOFF MINI-ZBD Zigbee Dry Contact Smart Switch. Unlike standard relays that switch live power, this module uses a potential-free dry contact (NO/NC) output — making it ideal for systems that expect a simple switch signal rather than voltage.

Key Features

• True Dry Contact Output (NO/NC) – Safely controls garage door motors, gate openers, boilers, solenoid valves, fire alarms and more without modifying existing wiring or sending voltage to the controlled device.
• Flexible AC & DC Power – Works with 100–240V AC or 12–48V DC input. Perfect for standard home installations as well as solar, battery, RV or low-voltage systems.
• Zigbee 3.0 + Router Function – Reliable low-power mesh connectivity. Acts as a Zigbee router to extend and strengthen your network.
• Direct Control of Low-Power DC Loads – Supports DC motors and solenoid valves up to 8W (or 24V DC / 2A resistive).
• Inching / Pulse Mode – Essential for most garage door and gate motors that require a momentary contact.
• Excellent Home Assistant Support – Works natively with ZHA and Zigbee2MQTT for fully local control. Also compatible with eWeLink, SmartThings, Alexa and other Zigbee hubs.
• Ultra-Compact Design – Measures just 41 × 43 × 21.5 mm, making it easy to install in tight spaces or control boxes.

Ideal Applications

• Garage door automation
• Electric gate / boom barrier control
• Boiler and heating system control
• Irrigation valves and pumps
• Low-voltage DC motors and solenoids
• Any device that uses a dry contact / push-button input

Technical Specifications

Note: A Zigbee 3.0 hub/coordinator is required (e.g. SONOFF ZBDongle-E/P, ZBBridge, Home Assistant Green + Zigbee stick). Do not connect AC and DC power sources at the same time.

Upgrade your garage door, gate or dry-contact devices with reliable Zigbee automation. The SONOFF MINI-ZBD is one of the most flexible and compact dry contact solutions available for Home Assistant and smart home installations.
