Enjoy effortless control of smart devices from different brands, all through one unified ecosystem. Build a truly interoperable smart home with Matter technology. 【Flexible AC/DC Power Supply Support】Designed for versatility, the MINI-D supports powered by AC (100–240V) or DC (12–48V) power sources, enabling easy installation in residential, industrial, or custom control environments. Perfect for various wiring scenarios and locations. 【Dry Contact Output – Supports NO & NC Configurations】The SONOFF MINI-D features dry contact output with both Normally Open (NO) and Normally Closed (NC) options, allowing flexible control of a wide range of signal-based systems. It’s ideal for operating boilers, garage door openers, access control panels, and other devices that rely on non-voltage triggering. Perfect for integrating smart control into traditional low-voltage or relay-based systems. 【Optimized for DC Low-Power Motors (Max 8W)】Specially engineered to control low-power DC motors or solenoid valves (up to 8W), the MINI-D offers an ideal solution for smart irrigation, motorized curtains, or gate systems that run on low-voltage DC circuits. 【Integrated with Contactor Control – Manage High-Power Loads Safely】When paired with a contactor, MINI-D allows a low-power control circuit to safely switch high-power electrical systems, such as industrial equipment or HVAC units. This not only increases safety and energy efficiency but also allows precise smart control over large loads.

【Matter Compatibility】Effortlessly integrate with major smart home platforms and synchronize with your existing Matter-enabled devices for a unified, connected experience. 【Apple Ecosystem Compatible】Works seamlessly with your entire Apple ecosystem - Siri, iPhone, iPad, and Apple Watch. Control your devices via app, voice, or smart scenes. 【Smart Scene】 Create personalized automation scenarios across both the SONOFF and Matter ecosystems for a truly synchronized smart home. 【Detach Relay Mode】After enabling this feature, the physical buttons are separated from the relay status. This effectively prevents the smart light from going offline due to physical button operations, ensuring the smart light remains controllable at all times. 【Night Switch Locator】Features an LED indicator, making the switch easy to find in the dark. You can adjust the brightness of the light to suit your preference, ensuring it won't disturb your rest.

【Ultra-Compact Design – Fits EU/86/120-Type Mounting Boxes】The ZBMINIR2 smart switch features a miniature form factor that easily fits inside EU-type, 86-type, and 120-type electrical boxes.
