Product Description

 

SONOFF MINI D Matter Dry Contact Smart Switch: ESP32 chip, AC/DC input, garage door/HVAC/irrigation control. Works with eWeLink/Alexa/Google Home.

Specification

1. Core Product Positioning

As SONOFF's first mini dry contact device with Matter, the SONOFF MINI D Matter Dry Contact Wi-Fi Smart Switch is a professional-grade dry contact smart switch designed for low-power control scenarios. Equipped with an upgraded ESP32 chip and isolated dry contact relay, it focuses on safe and stable control of high-current or low-voltage devices-making it an ideal choice for smart home, industrial automation, and outdoor facility management.

2. Core Features & Technical Advantages

• Matter Ecosystem Compatibility: As a Matter dry contact switch, it seamlessly connects to mainstream smart ecosystems (eWeLink, Alexa, Google Home, Apple Home, Home Assistant). This allows cross-platform control and scene linkage, eliminating the hassle of "ecosystem fragmentation" and enabling unified management of multiple smart devices.
• Upgraded ESP32 Chip: The built-in ESP32 chip enhances Wi-Fi stability and processing speed, ensuring smooth remote control (no lag during device on/off) and reliable OTA updates via eWeLink-keeping the switch's functions up-to-date without manual replacement.
• Dry Contact & AC/DC Input: The dry contact relay design enables "signal-only control" of isolated circuits, avoiding direct electrical connection with high-current devices (e.g., contactors, solenoid valves). It supports both AC and DC input, adapting to diverse power supply environments (home AC 110-240V, industrial DC 12-24V).
• Smart Timer & Scene Linkage: Built-in smart timer function for scheduled on/off (e.g., setting irrigation systems to run at 7 AM daily). It also supports custom smart scenes-such as "auto-turn off HVAC when garage door closes" or "trigger sprinklers when temperature exceeds 30°C"-maximizing energy efficiency and convenience.

3. Key Application Scenarios

Tailored to multiple scenarios with its safe and versatile design, it solves core control needs for different devices:

 

• Garage Door Control: As a garage door smart switch, it connects to garage door openers via dry contact, enabling remote on/off and status monitoring via eWeLink. You can check if the garage door is closed anytime, avoiding security risks from leaving it open.
• HVAC & Heating Systems: As an HVAC smart switch, it controls contactors for heating/cooling systems. Link it with thermostats to realize "auto-adjust HVAC based on room temperature," creating a comfortable living environment while reducing energy waste.
• Irrigation & Sprinklers: As an irrigation system smart switch, it triggers sprinkler solenoid valves. Set timed irrigation schedules (e.g., 30 minutes every other day) or link to rain sensors for "rainy day auto-pause"-saving water and simplifying garden management.
• Access Control & Barriers: Compatible with access control systems and arm barriers, it enables remote opening via eWeLink (e.g., unlocking the community barrier for visitors) and supports group control of multiple barriers in large compounds.

4. User-Friendly Control & Safety Design

• Multi-Way Control: Supports both remote control (eWeLink APP, voice commands via Alexa/Google Home) and local settings (power-on state, inching mode). The "detach relay" function allows temporary disconnection of the relay for maintenance, ensuring operational safety.
• Safety Protection: The isolated dry contact design prevents high-current feedback from damaging the switch or connected devices. The compact mini size fits easily into junction boxes or equipment cabinets, saving installation space.
• Group Control & Permission Sharing: Manage multiple SONOFF MINI D switches in groups (e.g., "all irrigation zones") for one-click control. The main eWeLink account can share device permissions with family members or staff, avoiding repeated setup.

5. Package & Quality Assurance

The package includes the SONOFF MINI D switch, wiring instructions, and mounting accessories-with detailed diagrams for easy DIY installation (no professional electrician required). Backed by SONOFF's strict quality control, each switch undergoes 3 rounds of testing (circuit stability, Wi-Fi connectivity, relay durability) and comes with a 2-year warranty.

 

From ESP32 smart switch performance to Matter dry contact switch compatibility, and from garage door to irrigation system control, the SONOFF MINI D meets both home and light industrial smart control needs-providing a safe, stable, and user-friendly solution for smart automation upgrades.
