Sonoff MINI-ZBD: Smart Zigbee Dry Contact Relay for Garages, Gates and Boilers
The Sonoff MINI-ZBD is a Zigbee smart relay with dry contact designed to make traditional devices smart, such as garage doors, automatic gates, boilers, heat pumps, irrigation systems, solenoid valves, and small DC motors. Thanks to the NO/NC dry contact output, it allows you to control devices that require a simple pulse or clean signal, without invasively modifying the existing system. Compact and versatile, the Sonoff MINI-ZBD supports 100-240V AC or 12-48V DC power supply, making it suitable for both traditional home systems and low-voltage automations. Through a compatible Zigbee hub, it can be managed via app, integrated into smart scenarios, and used with platforms such as eWeLink and Home Assistant for remote control, timers, automations, and intelligent home management. In addition to its smart switch function, the MINI-ZBD can also work as a Zigbee router, helping to extend the mesh network coverage and improve signal stability. It is the ideal choice for those looking for a reliable, small, and powerful Zigbee dry contact module, perfect for smart home applications, garages, heating, irrigation, and advanced home automation projects.
Ideal for Garages, Gates and Heating Systems
The Sonoff MINI-ZBD is a smart Zigbee dry contact relay ideal for automating various home and technical devices, such as garage doors, HVAC and heating systems, irrigation, DC solenoid valves, small motors, electric screens, motorhomes and boats with 12V-24V electrical systems. Thanks to its compatibility with smart scenarios and home automation, it allows you to intelligently control traditional devices via a compatible Zigbee hub.
Zigbee signal more stable and expanded coverage
The Sonoff MINI-ZBD can function as a Zigbee router, helping to extend the coverage of the home automation network and improve signal stability between hubs, sensors, and compatible smart devices. Thanks to the signal boosting mode, it helps reduce weak connection areas and makes Zigbee communication more reliable even in large environments, multi-room homes, garages, or areas far from the main gateway.
Smart remote control for garage door via app
With Sonoff MINI-ZBD you can make your garage door smart and control it conveniently from your smartphone via app, even when you're away from home. The Zigbee module with dry contact connects to the garage opening system and allows you to activate the command remotely, create automations and manage access in a more practical and intelligent way. An ideal solution for home garages, car boxes, sectional gates and existing automations compatible with dry contact input.
Smart control for SG-Ready heat pumps
With Sonoff MINI-ZBD you can automate SG-Ready heat pumps via dry contact, intelligently managing the different operating modes of the system. The Zigbee module allows you to optimize consumption, comfort and energy costs, integrating the heat pump into your smart home. Ideal for creating automations with photovoltaic systems, convenient time slots or home automation scenarios dedicated to home heating and air conditioning.
Smart personalized irrigation programs
Smart control for low-power DC valves and motors
It allows you to intelligently control solenoid valves, pumps and small DC motors up to 8W, making it ideal for DIY projects and home automation. It can be used for drip irrigation systems, CO2 valves for aquariums, pet water fountains and small vending machines. Thanks to the clean contact and Zigbee control via a compatible hub, it allows you to create timers, scenarios and personalised automations directly from the app.
# Zigbee Local Control Integration for Home Assistant --- ## Overview Home Assistant offers several solutions for **local Zigbee control**, without relying on external clouds. Here are the main options: --- ## 🔧 Main Integrations ### 1. **ZHA (Zigbee Home Automation)** - ✅ **Native** in Home Assistant - ✅ No additional software required - ✅ Local and fast - 📡 Requires a Zigbee coordinator (USB or network) ### 2. **Zigbee2MQTT** - ✅ More advanced and flexible - ✅ Huge device compatibility - ✅ Local via MQTT broker (Mosquitto) - 📡 Requires coordinator + MQTT add-on --- ## 📡 Compatible Coordinators | Coordinator | Protocol | Notes | |-------------|----------|-------| | **Sonoff Zigbee 3.0 USB Dongle Plus** | Zigbee 3.0 | Recommended | | **ConBee II / III** | Zigbee | Dresden Elektronik | | **HUSBZB-1** | Zigbee + Z-Wave | Dual combo | | **Tube's ZB-GW03** | Zigbee (LAN) | Network coordinator | --- ## ⚙️ ZHA Setup ```yaml # configuration.yaml (if not configured via UI) zha: usb_path: /dev/ttyUSB0 database_path: /config/zigbee.db ``` ### Via UI: 1. **Settings** → **Devices & Services** 2. **+ Add Integration** 3. Search for **"ZHA"** 4. Select the serial port 5. ✅ Done! --- ## ⚙️ Zigbee2MQTT Setup ### 1. Install add-ons: - **Mosquitto Broker** - **Zigbee2MQTT** ### 2. Zigbee2MQTT configuration: ```yaml # /addon_configs/zigbee2mqtt/configuration.yaml homeassistant: true permit_join: false mqtt: server: mqtt://localhost:1883 user: your_user password: your_password serial: port: /dev/ttyUSB0 adapter: ember # or zstack, deconz advanced: network_key: GENERATE pan_id: GENERATE channel: 11 # or 15, 20, 25 ``` ### 3. MQTT integration in HA: ```yaml # Automatic via discovery # Enable in Zigbee2MQTT: homeassistant: true ``` --- ## 🆚 ZHA vs Zigbee2MQTT | Feature | ZHA | Zigbee2MQTT | |---------|-----|-------------| | Installation | ⭐ Simple | 🔧 Medium | | Device compatibility | Good | 🏆 Excellent | | Advanced customization | Limited | 🏆 Full | | Zigbee mesh | ✅ | ✅ | | External converters | ❌ | ✅ | | Active community | ✅ | 🏆 Very active | --- ## 🔒 Security & Best Practices ```yaml # Disable join after pairing permit_join: false # Use a dedicated network key advanced: network_key: [your, 16, byte, key] # Separate IoT network (VLAN) # Zigbee is local → no internet required ``` --- ## 📊 Useful Automations ```yaml # Example: light on motion automation: - alias: "Motion Light" trigger: - platform: state entity_id: binary_sensor.motion_sensor to: "on" action: - service: light.turn_on target: entity_id: light.living_room data: brightness: 200 color_temp: 3000 ``` --- ## 🛠️ Troubleshooting ```bash # Check coordinator port ls /dev/ttyUSB* ls /dev/ttyACM* # HA logs # Settings → System → Logs → Filter "zha" or "zigbee2mqtt" # Zigbee channel check (avoid WiFi overlap) # WiFi 2.4GHz channels 1,6,11 overlap with Zigbee # Use Zigbee channel 15, 20, or 25 ``` --- ## 📦 Recommended Devices | Type | Recommended Brand | |------|------------------| | Bulbs | IKEA Tradfri, Philips Hue | | Sensors | Aqara, Sonoff SNZB | | Switches | IKEA, Tuya | | Plugs | Sonoff S26R2ZB, IKEA | | Thermostats | Aqara TVOC, Danfoss | --- > 💡 **Tip:** For a solid mesh, use **routers** (powered plugs/bulbs) distributed throughout the home. Battery-powered sensors are **end devices** and don't extend the network.
