SONOFF MINI-D WiFi Smart Switch

Dry contact wiring
To ensure compatibility with the garage door motor, please short-circuit the terminals of the motor that were originally used to connect to the wall switch (the short-circuiting process is safe, so don’t worry). If the garage door motor operates after short-circuiting, it is compatible; if the motor does not operate, it is not compatible.

*Make sure all wires are connected correctly.

Introduction

MINI-D is a Wi-Fi dry contact smart switch that supports AC/DC power supply. It can be used to control motors, garage doors, and other dry contact input devices, offering remote control, voice control, and other functions through APP. It also supports the Matter protocol, allowing seamless integration with smart devices from other brands to build your home automation system.

Installation

Power off

WARNING
Please install and maintain the device by a professional electrician. To avoid electric shock hazards, do not operate any connection or contact the terminal connector while the device is powered on!

Wiring instruction

WARNING
AC and DC are not supported as power input at the same time! *To ensure the safety of your electrical installation, it’s essential either a Miniature Circuit Breaker (MCB) or a Residual Current operated Cicuit-breaker with Integral Overcurrent protection(RCBO) with an electrical rating of 10A that meets national safety standards has been installed before the MINI-D. An overcurrent protection device with a rated current of 3A needs to be used in the control circuit of the MINI-D.

DC low power load wiring

Dry contact wiring

1. Applicable to devices that can be controlled via dry contact.
2. To ensure compatibility with the garage door motor, please short-circuit the terminals of the motor that were originally used to connect to the wall switch ( the short-circuiting process is safe, so don’t worry). If the garage door motor operates after short-circuiting, it is compatible; if the motor does not operate, it is not compatible.

Make sure all wires are connected correctly.

Power on

 

 

After powering on, the device will enter the Pairing Mode during the first use. The LED indicator changes in a cycle of two short and one long flash and release. *The device will exit the Pairing Mode if not paired within 10mins. If you want to enter this mode, please long press button for about 5s until the LED indicator changes in a cycle of two short and one long flash and release.

Check the Device Status
External Switch Type: The device’s factory default is the rocker switch. To switch to the momentary switch, you need to short-press the device button three times. If the blue light flashes three times, it means the switch is successful.
