## Description

MQTT, short for Message Queuing Telemetry Transport, is a lightweight messaging protocol, ideal for situations where small code size and unreliable or bandwidth-constrained networks matter. It uses a publish-subscribe model, which makes it particularly suitable for machine-to-machine communication in networks with remote locations or devices with limited resources, such as in the Internet of Things (IoT).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.powerio.com/hub/powerio-r-system/en/applications/available-apps/mqtt-broker.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
