A small script to log periods of time when there is no Internet connection. When the Internet connection is restored, the script sends a text notification to the telegram bot.

Brief explanation: Python script performs ping requests for two IP addresses in the loop. When the script fails to register a response from the requested IP addresses, it remembers the crash time and writes it to an external *.txt file. After a while, when the Internet reappears and the script has at least one response from the requested IP address, it notifies the user via the telegram bot.

Example of notification telegram message:

This solution is one part of the personal smart home idea that runs on the Raspberry PI board(s).
