To subscribe to the MQTT broker you must satisfy the following prerequisites:

  • You must have access to an MQTT client, such as the HiveMQ Websocket Client.

If you are using the HiveMQ client, refer to the HiveMQ documentation site to view the user guide.

MQTT Broker Overview

Subscribing to Connectivity Management's MQTT broker allows you to:
  • Forward data from non-IP subscribers to your own MQTT client.
  • Send data from your MQTT client to your non-IP subscribers.

The Services>MQTT Users section of Connectivity Management allows you to set up MQTT user credentials, which can be used to access the Connectivity Management MQTT broker using an MQTT client.


If you want to forward data to an MQTT broker instead of an MQTT client, you will need to set up an MQTT data feed.

Please refer to the User Guide for further information on how to do this.

  1. Select an MQTT client that you will use to connect to the Connectivity Management MQTT broker.

    You must use the user credentials that were defined in step 2 when connecting to the broker.
