Product detailed description

⚙️ Sonoff Mini D - Matter Dry Contact Relay

The SONOFF MINI-D is a smart Wi-Fi+Bluetooth relay module supporting NO/NC switching and dry contact output capabilities.

It is natively compatible with the eWeLink smart home system and also supports the Matter smart home standard, meaning it can be used with all Matter-compatible systems, such as Apple Home or SmartThings.

The MINI-D enables remote control and automation of various devices, such as garage doors, HVAC systems, and irrigation setups. This is where its specialty lies, as its contact is voltage-free (dry contact), giving you immense flexibility.

Key Features

Broad Compatibility with the Matter Ecosystem:
The Matter protocol ensures seamless integration with platforms like Amazon Alexa, Google Home, and Apple Home, simplifying the management of your smart home devices.

Dry Contact Control (Potential-Free Relay)

Dry contact control allows the device to break or connect two points without transferring voltage from its power source. This enables switching independent circuits (for instance, switching a 12V or 24V circuit even if the relay is powered by a 230V mains). This ensures complete isolation of the module's power supply from the connected load, increasing safety and wiring flexibility.

Garage Door Automation:
With the MINI-D, you can remotely open or close your garage door using your smartphone, increasing convenience and safety (it functions like a classic push-button for the motor).

Automated Valve Control:
It enables switching of thermoelectric actuators, making it easier to automate additional tasks.

High-Power Switching with Low-Power Circuits:
The integration of a 2A relay safely and effectively controls high-power contactors using low-power control circuits.

Automation of Low-Power Solenoid Valves / DC Motors:
Specially designed to control DC solenoid valves or motors with a power consumption of up to 8W, providing a cost-effective and reliable solution for various applications.

"Detach Relay" Feature Support:
The SONOFF MINI-D allows the physical switch (e.g., a wall switch) to operate independently of the relay state.

How It Works

During normal operation, the wall switch (connected to the S1-S2 terminals) toggles the relay state with each activation, turning the connected device or circuit on or off. When the "detach relay" function is active, the wall switch no longer directly changes the relay state, but the device still detects changes in the switch's status. This input can then be repurposed for other tasks using smart controls.
