# IP Address Change Notifier

==========================

This script is designed to monitor and notify when the public IP address of a device changes. It uses various notification methods, including email, Telegram, and Nextcloud Talk.

## Configuration

---

The script relies on a configuration file named `config.ini` to store settings. The file should be in the same directory as the script.

### General Settings

* `check_interval`: The interval in seconds between IP checks (default: 300)
* `notify_methods`: A comma-separated list of notification methods (default: email)
* `last_ip_file`: The file to store the last known IP address (default: last_ip.txt)

### Email Settings

* `from`: The sender's email address
* `to`: The recipient's email address
* `server`: The SMTP server address
* `port`: The SMTP server port (default: 465)
* `user`: The SMTP username
* `pass`: The SMTP password

### Telegram Settings

* `bot_token`: The Telegram bot token
* `chat_id`: The Telegram chat ID

### Nextcloud Talk Settings

* `url`: The Nextcloud URL
* `token`: The Nextcloud token
* `room`: The Nextcloud room ID

## How it Works

---

1. The script loads the configuration from `config.ini`.
2. It checks the public IP address using the `get_public_ip` function.
3. If the IP address has changed, it sends a notification using the specified methods.
4. The last known IP address is stored in the `last_ip_file`.

## Notification Methods

---

The script supports the following notification methods:

* Email: Sends an email using the specified SMTP server and credentials.
* Telegram: Sends a message using the Telegram bot token and chat ID.
* Nextcloud Talk: Sends a message using the Nextcloud URL, token, and room ID.

## Running the Script

---

To run the script, simply execute it using Python:

```bash
python ip_notifier.py
```

Note: Make sure to replace `ip_notifier.py` with the actual script name.

## Troubleshooting

---

If you encounter any issues, check the script's output for error messages. Ensure that the configuration file is correct and that the notification methods are properly set up.
