refresh-bot

A basic bot that:

1. Opens up a browser, allowing you to navigate to a particular page
2. Repeatedly refreshes the page
3. Takes a screenshot each time and compares them for any changes
4. Sends a telegram alert whenever a change is found.

Use it for a simple alert system to detect when a change happens on a website.

Tested on Raspiberry Pi running Raspberry Pi OS.
