Node-RED

ThingPark Enterprise All-in-One embeds a Node-RED component to optimize the solution's integration with external Application Servers.

The default Node-RED flow supports MQTT protocol with an embedded MQTT broker. <<<<<<< HEAD This is called Uplink/Downlink flow.

caution

Do not delete this flow from Node-RED, otherwise data reporting to your Application Servers will be stopped.

This section describes the essential things you need to know about the embedded Node-RED.

If you are not familiar with Node-RED, you may consult these tutorials.

This is called Uplink/Downlink flow, it constitutes the unique interface with the LoRaWAN Network Server embedded in ThingPark Enterprise All-in-One.

Additional flows are available off-the-shelf to support a seamless integration with BACnet and Modbus protocols.

caution

Do not delete the Uplink/Downlink flow from Node-RED, even if you do not need MQTT protocol to interface with your Application Servers.

This flow remains mandatory for proper operation of other Node-RED flows. Deleting it will cause data reporting to your Application Servers to stop working.

caution

Use of Node-RED nodes in "server" mode (e.g. modbus server) - with periodic polling from external client applications - has not been benchmarked by Actility. Server mode may have negative impacts on ThingPark Enterprise-All-in-One performances. Such potential impact on performance remains under the entire responsibility of the solution's operator. :::
