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.
A lot of useful nodes are provided in Advantech NodeRed Server IoTGateway installer, including node-red-contrib-flow-dispatcher nodes, node-red-contrib-susi and node-red-contrib-virtual-app-node.
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 |
