Understanding the Retrieve Device Identification Information Node

In this quick tutorial, we will cover Understanding the Retrieve Device Identification Information Node. Today, you will learn the ins and outs of the Retrieve Device Identification Information Node and how it’s used in Catenis Flow.

In this video we will cover:

• What information this node retrieves
• How to use a unique name instead of a device ID in the Catenis Administrative interface
• Importing an example flow

Prerequisite

• A Free Catenis Development account or Production account
• Node-RED installed on either a local or cloud environment
• Catenis Flow Pallet installed on Node-RED
• A Catenis Virtual Device configured on Node-RED
• Basic understanding of how to use Node-RED

After watching Understanding the Retrieve Device Identification Node, feel free to watch the next video, Working with the Retrieve Device Identification Node, to further expand your knowledge.

Hi, this is Claire for Blockchain of Things.

Today, you will learn the ins and outs of the Retrieve Device Identification Info Node, and how it’s used in Catenis Flow.

The Retrieve Device Identification Info Node can be used to retrieve

information about a Catenis Device,

whether this node is a hub or a gateway, the client ID it belongs to, and the device name.

Name the node using the name field and set a Catenis Virtual Device in the connection field.

Enter the device ID of the Catenis Device you wish to

retrieve information for in the device ID field.

This does not have to be the same device you use to configure the node in field 2.

If you have associated a unique name to your device in your Catenis Administrative Interface

and you prefer to use the unique name instead of a device ID,

tick off the box in the product unique ID field and enter the unique name

you call your device in the device field instead of the device ID.

Now, let’s take a look at the example flow found at this link:

Copy the example flow.

Click the Node-RED hamburger menu, and click import to display the import flow dialog box.

Paste the flow into the import box and click the import button.

This flow is a working example implementing the Retrieve Device Identification Info Node.

Note, that after importing the example flow,

you will need to set the Catenis Flow Nodes to your own previously configured virtual device.

Before you can use the example JSON object, you will need to replace the example ID with your own device ID.

You can pause this tutorial now to explore this flow on your own.

In the next video, you’ll learn how to create this flow from the ground up.
