IoTGateway/Node-Red

Advantech implements some Node-RED nodes for better development experience.

Node-RED for Alljoyn

We plan to provide three kinds of Node-RED nodes for Alljoyn feature.

• Action Handler
• Event Reader & Rule Engine
• ControlPanel Client

Installation

You can install the node-red-contrib-alljoyn via NPM, or download it on GitHub.

Usage

Please refer to README.

Node-RED for WSN

Wireless Sensor Network(WSN) is supported on Advantech WISE-3310 and all provided features are basically described by REST API respectively. For users to quickly access the WSN features and build the prototype control logic flow of application before knowing the detailed REST API manipulation and programming, We provide the following Node-Red nodes to easily read the information and access functions of WSN on Advantech WISE-3310.

• wsn-gw
• wsn-senhub

Usage

1. In the browser, enter Advantech IoT Gateway's IP address with Node-RED port 1880 to open Node-RED web page.
2. On the left of the page, scroll down to find wsn-related nodes in Advantech section as depicted below.
3. Drag and drop wsn-related nodes into Sheet to start building control flow.

wsn-gw Node

Node to get the information and set functions of a ADVANTECH WSN gateway platform, triggered by an input message. Outputs a msg with msg.payload containing the JSON description of reading or result. During configuration, it will automatically detect available options for Network, Category, and Attribute in real time.

Configuration

• Drag and drop wsn-gw node into Sheet
• Double click on the node to open Edit wsn-gw Node window for configuration as below
• Start from the top item in the window, it will automatically detect and list the available options currently.

Items in Edit Window

• Operation : Get or Set
• Net Type : Supported network types on the platform
• Net ID : List of available network interfaces of selected Net Type above. Options are listed in the format of :

Interface Name(Interface MAC)
ex. WSN0(00170d0000010203)

• Category : Class of Attributes
• Attribute : List of Attributes in selected Category above

Example: Get SensorHub List

This example shows how to build a control flow to get a list of sensorhub MAC address on selected network interface.

1. Build a flow using inject as input node to wsn-gw node, and debug as output node.

2. Double click on wsn-gw node to open Edit wsn-gw node window and configure the node as below

Item	Value
Operation	Get
Net Type	WSN
Net ID	WSN0(your Interface MAC)
Category	Info
Attribute	SenHubList

3. Connect nodes together and click on Deploy

4. Click on the input node and you will see the result in debug window

5. The output in the debug window is a JSON string describing the result

{ 
    "StatusCode": 200, 
    "Result": { 
        "n": "SenHubList", 
        "sv": "00170d0000603a0e,00170d0000602e5a,00170d0000304ab4,00170d000060339c", 
        "asm":	"r" 
    } 
}
