Step 5 - configuring Node-RED

ThingPark Enterprise All-in-One uses Node-RED to interface with external application servers. The default Node-RED flow supports MQTT protocol with an embedded MQTT broker.

Additional flow samples are available off-the-shelf to support a seamless integration with BACnet and Modbus protocols. To learn more about the Node-RED functions embedded in TPE All-in-One, see Node-RED.

The task described in this page describes how to change the default MQTT configuration to set an external MQTT broker instead of the pre-configured internal broker.

note

If you want to keep the internal MQTT broker, you may ignore this step and directly jump to the next step Step 6 - provisioning your devices.

1. Connect to Node-RED by clicking Node-RED from the left panel of the user interface.

2. Click Sign in with ThingPark Enterprise and eventually sign-in again with your password.

   

3. To modify the MQTT broker configuration, double-click the MQTT /uplink-topic node of the UPLINK/DOWNLINK flow, then configure the MQTT node:

   

   You may change here the standard MQTT settings:

   • Topic: the topic where you will receive the uplinks
   • QoS, Retain: standard MQTT attributes
   • Name: the display name of the node.

4. Click on the server "pen" icon to configure the MQTT server: the default configuration is the local MQTT broker, but you may change it to configure an external MQTT broker:

   

   You may change here the main server attributes: server address, server security, server secure connection...

5. Do not forget to apply your configuration by clicking . Then click to save the MQTT node configuration.

6. Repeat the same steps for the MQTT /downlink-topic node, the server configuration is global to both nodes.

7. After you have completed all your Node-RED reconfiguration, you must click Deploy to push your new flow on the server.

   

   -> After few seconds, you should see that your MQTT nodes get connected:
