# Usage Guide
This guide covers how to run the Meshtastic Network Monitor in various modes.
## Prerequisites
Ensure you have installed the dependencies:
```bash
pip install -r requirements.txt
```
## Basic Execution
### USB / Serial Connection
If your Meshtastic device is connected via USB:
```bash
python3 main.py
```
The monitor will automatically detect the serial port.
### TCP / Network Connection
If your Meshtastic device is on the network (e.g., WiFi):
```bash
python3 main.py --tcp <IP_ADDRESS>
```
Example:
```bash
python3 main.py --tcp 192.168.1.10
```
## Command Line Options
| Option | Description |
| :--- | :--- |
| `--tcp <IP>` | Connect to a device via TCP/IP instead of Serial. |
| `--ignore-no-position` | Suppress warnings about routers without a valid GPS position. Useful for portable routers. |
| `--help` | Show the help message and exit. |
## Running in the Background
To run the monitor continuously, you might want to use `nohup` or a systemd service.
**Using nohup:**
```bash
nohup python3 main.py > monitor.log 2>&1 &
```
## Interpreting Output
The monitor outputs logs to the console (and `monitor.log` if redirected).
### Common Log Messages
- **`INFO - Connected to radio...`**: Successful connection to the Meshtastic device.
- **`INFO - Starting analysis cycle...`**: The monitor is beginning a new round of checks.
- **`WARNING - Congestion: Node X reports ChUtil Y%`**: The specified node is experiencing high channel utilization.
- **`INFO - Sending traceroute to...`**: The monitor is actively testing a node.
## Reports
Reports are generated in the `reports/` directory.
- **Format**: `report-YYYYMMDD-HHMMSS.md` (and `.html` if enabled).
- **Data**: `report-YYYYMMDD-HHMMSS.json` contains the raw data.
See [Report Generation](report_generation.md) for details on how to regenerate reports.
