HiveMQ Cloud Free Cluster Overview

Create MQTT Client Credentials

To connect an MQTT client to your cluster, you need to define the MQTT credentials that allow the clients to access the cluster.

  • To create an MQTT credential, enter a Username and Password in the credentials input area of the Access Management tab for your HiveMQ Cloud cluster and select Add.
    The Access Management tab adjusts to display the credentials that you add in the Active MQTT Credentials area.

You can add and delete MQTT credentials for your HiveMQ Cloud cluster as needed.
Access Management - Create MQTT Credentials
Keep the Credentials page of your cluster open. To complete this procedure, you need the URL, port, and MQTT credential information from the Overview and Access Management tabs.

Test Your New HiveMQ Cloud Cluster

Once you create your MQTT credentials, you are ready to connect an MQTT client and test your connection.

The following procedure shows you how to use the open-source command-line tool MQTT CLI to connect an MQTT client and test your connection.

We use the MQTT CLI for ease of use and to simplify the explanation of this example procedure. However, you are free to use whichever tool and method you prefer.
For instructions with other tools, check the tooling information that is available on the Getting Started tab of the Cluster Details page for your HiveMQ Cloud cluster.


Download and install the current version of the MQTT CLI.
Documentation and download packages with complete installation instructions are available at no cost on GitHub.
An introductory tutorial for the MQTT CLI is available on YouTube.

Connect an MQTT Client

  1. To start the MQTT CLI in shell mode, open a terminal window and enter the following command:

    mqtt sh

    The MQTT CLI starts and displays a list of useful options and commands.

  2. To connect to your HiveMQ Cloud cluster, type the following command with the appropriate information from your Clusters page and press enter:

    con -h  <cluster-url> -p <port-number> -s -u <mqtt-credentials-username> -pw <mqtt-credentials-password>

    Information about the HiveMQ Cloud connection displays.
    This is your first connected MQTT client.

    HiveMQ Cloud only allows secure TLS connections. Adding an -s flag to the connect command opens a secure connection to the MQTT Broker with the default SSL configuration.
  3. To create another connected client and test your cluster, open a second terminal window (keep your original terminal window open) and enter the following command once more:

    mqtt sh
  4. Copy and paste the connection command that you created in the first window to the second window and press enter.
    Information about the second HiveMQ Cloud connection displays.
    This is your second connected MQTT client.

Publish/Subscribe Test

  1. In the terminal window of the second MQTT client, enter:

    sub -t testTopic -s

    This command subscribes the second MQTT client to all messages that are published to the topic testTopic.

    In shell mode, adding the -s flag to the command blocks the MQTT CLI console so that the incoming messages are printed out to the user.
  2. In the first terminal window, enter:

    pub -t testTopic -m Hello

    This command makes the first MQTT client a publisher and publishes the message Hello with the topic testTopic.
    The message Hello appears immediately in the terminal window of the second MQTT client.

  3. To publish another message, enter the following command in the first terminal window:

    pub -t testTopic -m Goodbye

    This command publishes the message Goodbye with the topic testTopic.
    The message Goodbye appears immediately in the terminal window of the second MQTT client.

Try Out the HiveMQ WebSocket Client

Your Free HiveMQ Cloud package also supports MQTT over WebSocket on port 8884. Once you create a Free HiveMQ Cloud cluster you can use the public HiveMQ WebSocket client to test the connection. The graphical view of the public WebSocket client provides a convenient way to explore and experiment with MQTT functionality.

Access the HiveMQ WebSocket Client

  1. To get started with the HiveMQ WebSocket Client, go to the HiveMQ WebSocket Showcase.

Connect to Your Free HiveMQ Cloud Instance

  1. In the Host field, enter the hostname of your Free HiveMQ Cloud cluster from your Cluster Details page.

  2. In the Port field, enter 8884 , the default port for secure WebSocket communication.

  3. Since HiveMQ Cloud only accepts secure MQTT communication, select the SSL checkbox to activate TLS for the WebSocket client.

  4. To establish a connection to your HiveMQ Cloud instance, select Connect.

    HiveMQ WebSocket Showcase

Publish to Your Free HiveMQ Cloud Instance

  1. To publish a message to a topic on your HiveMQ Cloud instance, expand the Publish panel of the WebSocket client.

  2. In the Publish panel, enter your desired topic, message payload, and quality of service level (QoS). To add a retained message flag to the message, select the Retain checkbox.

  3. To publish your message to your HiveMQ Cloud instance, select Publish.

    WebSocket Publish

Subscribe to Your Free HiveMQ Cloud Instance

  1. To subscribe with a topic filter to your HiveMQ Cloud instance, expand the Subscribe panel of the WebSocket client.

  2. In the Subscribe panel, select Add New Topic Subscription to create your desired topic filter.

  3. In the subscription dialog that opens, define the Color, QoS, and topic filter pattern for the subscription.

  4. To create the subscription for your HiveMQ Cloud instance, select Subscribe.
    Messages that are sent to the client for the defined topic subscription appear in the Messages panel.

    WebSocket Subscribe
