These nodes were modified from the original IBM node-red mqtt nodes to simplify the broker configuration in using along with the Sense Tecnic MQTT(STS-MQTT) platform. Most of the modification was intended to minimize the steps that users need to perform to connect to STS-MQTT, in which aims to provide stable MQTT connections with less connection errors.
Node: Each connection would require a unique client ID set up on sts-mqtt server
STS-MQTT-in node subscribes to a specified topic on STS-MQTT. If correct user credentials are provided, this node will return any messages from this topic.
In the Topic field, enter users/{username}/{topic name} to subscribe. For example, if user Tom would like to subscribes to topic "temperatureSensor", he would enter users/tom/temperatureSensor in the topic field.
Note: Please ensure that the username, client ID, topic all exist on STS-MQTT.
STS-MQTT-out node publishes to a specified topic on STS-MQTT. If correct user credentials are provided, this node will send in msg.payload to this topic.
In the Topic field, enter users/{username}/{topic name} to subscribe. For example, if user Tom would like to subscribes to topic "temperatureSensor", he would enter users/tom/temperatureSensor in the topic field.
Note: Please ensure that the username, client ID, topic all exist on STS-MQTT.
