Setup

This section describes how to setup a Node-RED server and prepare to connect it to The Things Stack.

Requirements

  1. Install Node-RED

Note: Node-RED v1.0.6 is current at time of writing and is used in this guide.

Setup

Run Node-RED and navigate to http://localhost:1880 (or the public address of your Node-RED instance). In your web browser, you should see something like:

Node-RED dashboard

On the left side, you can see various types of nodes that can be used in order to build flows. All nodes can be found in the Node-RED library.

The Things Stack Console provides the connection information needed for completing this integration.

In the Console, click Applications and choose the application you want to connect to Node-RED. Click Integrations in the left hand panel of the Console, and the MQTT submenu to view the MQTT Server info:

MQTT Server connection information

In this example, the built-in MQTT Server is configured by default on port 1883 for insecure connections and on port 8883 for TLS-secured connections.

In a later step, we will use this information to connect Node-RED to The Things Stack.
