# Blitzortung Lightning Notifier

This project connects to the Blitzortung lightning detection network and sends notifications to your devices when lightning strikes are detected near your specified location.

## Features

- Connects to Blitzortung's live WebSocket feed.
- Filters lightning strikes by your chosen location and radius.
- Sends rich notifications to your devices via [ntfy.sh](https://ntfy.sh/).
- Optionally displays details about the detectors involved in each strike.

## Usage

### Prerequisites

- Rust (edition 2021 or newer)
- [ntfy.sh](https://ntfy.sh/) account or topic (no registration required)
- Optionally, a `detectors.json` file for detector details

### Build

```sh
cargo build --release
```

### Run

```sh
cargo run --release -- \
    --center-lat <latitude> \
    --center-lon <longitude> \
    --ntfy <ntfy_topic> \
    [--delta <radius>] \
    [--detector-fetch]
```

## Detectors
If you enable `--detector-fetch`, make sure you have a valid `detectors.json` file in the project directory. This file should contain metadata about Blitzortung detectors.
