# MQTT

The following article describes how to set up and export to your MQTT broker.

## **Configuration**

This integration can be configured on the Export Configs tab in the Netmore Connect Portal.

For MQTT export, these fields can be configured:![](https://cdn.document360.io/58c1b868-b36b-492e-aea3-32180613f31f/Images/Documentation/image(64).png)

### **URL**

- **Definition**: Specifies the MQTT broker endpoint where the platform will publish messages.
- **Components**:
  - **Protocol** (`mqtt://` or `mqtts://`):
    - `mqtt://` is unsecured.
    - `mqtts://` is secured over TLS/SSL.
  - **Broker address** (e.g., `mq.netmoregroup.com`)
  - **Port** (e.g., `8883` for secure MQTT, `1883` for non-secure MQTT)
- **Usage**: Must match the MQTT broker’s listening interface. For TLS connections, use `mqtts://` with port 8883.

### **Topic**

- **Definition**: The MQTT topic to which messages will be published.
- **Usage**: Topics define routing paths in MQTT. Devices subscribed to this topic will receive the published data.
- **Best Practice**: Use structured topics (e.g., `device/{deviceId}/data`) to support hierarchical access and filtering.

### **Username**

- **Definition**: The MQTT username used for authenticating with the broker.
- **Usage**: Required if the broker enforces authentication. Often paired with a password (not shown in this form).
- **Security Tip**: Ensure this is stored securely and not exposed in client-side logs.

### **Certificate**

- **Definition**: Client-side certificate used for mutual TLS authentication.
- **Usage**: Required if the broker enforces client certificate validation.
- **Format**: Usually in PEM format including the certificate and optionally the private key.
- **Note**: Only used when `mqtts://` is selected.

### **Certificate Authority (CA)**

- **Definition**: Root or intermediate CA certificate used to validate the MQTT broker’s TLS certificate.
- **Usage**: Ensures the client trusts the broker’s identity during TLS handshake.
- **Format**: PEM format.
- **Required**: When using self-signed or private CA-signed broker certificates.
