🚗 SONOFF MINI-D — Smart Dry Contact Switch (Matter + WiFi, AC/DC)
Open your gate from your phone. The MINI-D is a Matter-certified dry contact smart switch with NO/NC/COM relay output, supporting both AC (100–240V) and DC (12–48V) input. Perfect for garage doors, gates, boilers, access control, and DC motors/solenoid valves up to 8W. Inching mode sends a pulse to trigger gate motors — just like pressing a remote button. MPN: MINI-D.
⚡ Key Features
- Dry Contact Output (NO/NC/COM) — isolated relay output for signal-based control; no power passes through the relay — safe for gates, garage doors, boilers, access panels, and HVAC
- Inching Mode (Pulse) — sends a brief pulse (configurable duration, e.g., 0.5 s) to trigger gate motors and garage door openers — exactly like pressing a remote button
- AC/DC Dual Input — power from AC 100–240V (mains) or DC 12–48V (gate motor battery, power supply, solar) — choose one at a time
- Matter Certified — works natively with Apple Home/Siri, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant
- DC Low-Power Motor Load (Max 8W) — directly control small DC motors, solenoid valves, and pumps up to 8W
- Contactor Control — use the dry contact to safely switch high-power circuits via an external contactor
- External Switch (S1/S2) — connect a physical wall switch alongside app and voice control
- eWeLink App — remote control, schedules, timers, smart scenes, and device sharing
- Voice Control — Apple Siri, Amazon Alexa, Google Assistant
- Compact — 43 × 41 × 21.5 mm — fits behind switches, inside junction boxes, or inside gate motor housings
