SONOFF's First MINI
Dry Contact Device with Matter
MINI Dry Wi-Fi Smart Switch (Dry Contact Relay)
Easy Control via the Matter Ecosystem
Matter breaks down barriers between different smart home ecosystems. It is designed to work across different platforms, including major operating systems and ecosystems like Amazon Alexa, Google Home, and Apple Home, making it easier for users to manage their smart home ecosystem, improve interoperability, and enhance overall user experience.
A Signal to Control Isolated Circuit
Dry contact (Voltage-free contact) acts purely as a bridge for signal transmission between two points, typically in the form of an open or closed circuit that does not have a direct power supply. The power supplied to the module is completely isolated from the switched load, which helps prevent electrical faults and enhances safety.
Upgrade Your
Garage Door System
Make your garage door smart with MINI-D which offers remote control and seamless automation. You can open or close your garage door from anywhere using a smartphone app. Upgrading to a smart garage door system provides greater control.
Building A Thermostat
Automation System
An automated thermostat system offers intelligent temperature control for homes and buildings,
optimizing comfort and energy efficiency. Its smart schedule can be customized according to your habits and is also integrated with other smart home devices. This not only enhances convenience but also helps reduce energy consumption, leading to lower bills and a more sustainable living environment.
Controlling A Large Current
with A Small Current
MINI-D has a relay with a rated current output of 2A. When integrated with the contactor, a low-power control circuit can safely and efficiently manage high-power systems without direct user intervention, which enhances safety, reduces power consumption in control circuits, and provides precise control over larger loads.

FAQ
1. What is MINI-D?
MINI-D is a Wi-Fi-enabled dry contact smart switch designed to control motors, garage doors, and other dry contact input devices. It supports remote control, voice control, and more via a mobile app.
2. What type of power supply does MINI-D support?
MINI-D supports both AC (alternating current) and DC (direct current) power inputs. Please refer to the product specifications for the exact voltage ranges. Note: Do not connect AC and DC power sources at the same time.
3. What types of loads are supported by the MINI-D output terminal?
Dry-contact input devices: Such as garage door motors and boilers in temperature control systems, which are triggered by a dry contact signal.
Low-power DC devices: Including small DC motors or solenoid valves, with a maximum load of 8W.
Note: The output terminal of the MINI-D supports only DC loads. AC loads are not supported and should not be connected under any circumstances.
4. Can I use MINI-D with other platforms like Apple HomeKit or SmartThings?
