If you are on Windows you can run sentinel too, there's nothing stopping you from it.

Make sure you have python installed, either of this will work (make sure you choose 2.x not 3.x):
https://www.python.org/downloads/
https://www.anaconda.com/download/

Clone sentinel github:
https://github.com/dashpay/sentinel

Open a terminal/console/cmd inside sentinel (or either type "cd folder" until you are inside)
pip install -r requirements.txt
If you get an error, make sure pip is on the path (or use the complete path to you python installation, ie. "C:\Program Files\Python\bin\pip" instead of pip".

Once done, setup a task to run every minute
schtasks /create /sc minute /mo 1 /tn "DesireSentinel" /tr \\python fullpath\to sentinel folder\sentinel.py
If you had problems with pip, make sure to use the full path to python here too, instead of simply python.


Good luck!
