# Update your firmware

{% hint style="info" %}
To update your monitors firmware, you'll need to be at your tank and connected to the monitor via bluetooth using the magnet wand and your mobile phone.
{% endhint %}

To check if there is a firmware update available, go to Additional Information in your tank monitor home screen. If there is a firmware update available, select Click to update firmware.

Follow the app instructions to connect to your monitor and begin the update. This may take a few minutes. Occasionally the update appears to fail, if this happens, check your firmware version in Additional information before trying again.

## 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://help.waterwatch.io/3.0.1/hardware-and-maintenance/firmware-updates/update-your-firmware.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.
