Introduction
Node-RED is a visual wiring tool for the Internet of Things and is provided by IBM Emerging Technologies. Node-Red has several features, including browser-based flow editing, built on Node.js and social development. Because of browser-based, the user can use it more easily. Node-Red is based on Node.js, so user can use its nodes by using JavaScript. Node-Red also have many active communities. If the user finds bugs, he can find a solution and fix it easily. The user can use JSON format string to import or export the created flow easily.
RMM server provides many restful API. But some API is maybe required complex parameter, it usually makes the user to call restful API more difficultly. Hance RMM team creates several common nodes in Node-Red. These nodes can help the user to use restful API that RMM server provided more easily and fast.
Node-Red Plug-ins Catogries
| Category | Description | Nodes |
|---|---|---|
| UI-Flow-Creator | Provid functions to auto-generate a dashboard flow with node-red-dashboard nodes. UI-Flow-Creator nodes depend on node-susi and node-susiiot packages to read data and control devices. | 1.nr_ui_flow_creator 2.ui_ui_creator_ctrl |
| WISE-Cloud |
WISE-Cloud provide nodes to communicate with RMM Agent. Sending data to agent, receiving messages from agent and response RMM RESTful requests. |
