This timer sents a messages via gotify if the time is up. The Gotify server was already part of my homeautomation setup, that I setup at another time on my Rasberry Pi. To get your own gotify-server follow these instructions: https://gotify.net/docs/install
To send the message a second .py-file named credentials.py is needed containing a dictionary named gotify in the following format:
gotify = {
'url': "GOTIFY-SERVER-URL",
'token': 'GOTIFY_TOKEN',
}
