## Paho

The [**Paho**](https://camel.apache.org/components/4.10.x/paho-component.html) component enables integration of applications with the MQTT protocol (version 3), facilitating communication between devices and systems in Internet of Things (IoT) environments.

<Callout type="important" title="IMPORTANT">
- Supports connection to external MQTT brokers to publish messages and subscribe to topics.
- Integrations **cannot** be used as an MQTT broker (only as a client).
- Compatible with MQTT protocol versions 3.1.1 and 3.1.
</Callout>

**URI Syntax**: `paho:topic`

### Main fields

*Path parameters*

| **Name** | **Description** | **Default** | **Type** |
|----------|---------------|------------|----------|
| `topic` (common) | (required) Topic name. | —  | String |


*Query parameters*

| **Name** | **Description** | **Default** | **Type** |
|----------|---------------|------------|----------|
| `brokerUrl` (common) | The MQTT broker URL. | tcp://localhost:1883 | String |

### Example

<Steps>
<Step>
The flow connects to the public MQTT broker (`test.mosquitto.org`) on port 1883 using the TCP protocol.
</Step>
<Step>
It subscribes to the topic named `sensedia-01` and waits for messages published to this topic.
</Step>
<Step>
When a message is received, the content (`${body}`) is logged with the message "Got message" followed by the message body.
</Step>
</Steps>

```yaml
- from:
    uri: "paho:sensedia-01"
    parameters:
      brokerUrl: tcp://test.mosquitto.org:1883
