IoTGateway/Node-Red for GW EIS
Contents
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. |
1.WISE-Cloud-Sender |
NodeRed Plug-ins Description
Node Name | Description | Input | Output |
---|---|---|---|
nr_ui_flow_creator | Auto-generate dashboard flow with node-red-dashboard nodes. Require node-susi and node-susiiot packages. |
Auto-generated an inject node after flow deployment. | Auto-generated outputs according to user selected groups after flow deployment. |
nr_ui_creator_ctrl | Control devices according injected values . Require node-susi and node-susiiot packages. |
SUSIIoT control information in 'topic' propery and control value in 'payload' property. | Control result returned by SUSIIoT. |
WISE-Cloud-Sender |
Send injected IPSO JSON string to RMM agent. |
A string in 'payload' property which will be passed to RMM agent. |
None |
WISE-Cloud-Receiver |
Receive messages from RMM agent with specified name and topics. |
None | The received message (or RESTful request) from RMM agent is included in 'req' property. |
WISE-Cloud-Responder |
Response RESTful requests. The injected data must contain the source request information. |
Source request is included in 'req' property and the corresponding response is in 'rep' property. | None |
