node-red-contrib-openbeken-subflow 1.0.0
OpenBeken support for Node-RED
node-red-contrib-openbeken-subflow
A high-performance Node-RED node designed specifically for OpenBeken flashed hardware. This node simplifies the integration of devices using Flag 10 (immediate MQTT state feedback) and includes a built-in watchdog timer to monitor device health.
Features
Closed-Loop Feedback: Automatically synchronizes with the device state using the .../1/get topic.
Watchdog Timer: Monitors device activity and updates the node status to "Offline" if no heartbeat is detected within 5 minutes.
Smart Sanitization: Accepts Booleans (true/false), Strings ("on"/off"), or Numbers (1/0) and converts them to the correct format for OpenBeken.
Zero-Config UI: Designed to work out of the box with Node-RED Dashboard 2.0.
Hardware Requirements
For the best experience, ensure your OpenBeken device has Flag 10 enabled. Open your device's web console and run:Backlog Flag 10 1; restart
Configuration
Broker: Select your MQTT Broker configuration node.
Topic Base: Enter the base MQTT topic of your device (e.g., BedroomFan). Do not include trailing slashes.
Input/Output
Input: Send a boolean true/false or string "on"/off" to toggle the device.
Output 1: Returns a clean boolean true/false based on the hardware's actual state.
Output 2: (Optional) Provides detailed status objects for logging or advanced logic.
Tips for Success
Dashboard 2.0: Simply wire a Dashboard "Switch" node to the input and back from the output for a perfectly synchronized UI.
LWT: This node relies on the device being "connected" to show online status. Ensure your MQTT Broker is configured to handle the device's Last Will and Testament (LWT).
