# LCT - Geofence Rule

The Geofence Rule enables the generation of alarms based on the geolocation of the device. Alarms can be triggered when the device enters, leaves, or both enters and leaves a predefined geofence area. This rule provides location-based monitoring, ensuring devices operate within desired geographical boundaries.

## 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://docs.g-iot.io/low-cost-tracker-full-device-guide-book/low-cost-tracker-greater-than-giots-functions/lct-rules/lct-geofence-rule.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.
