Okay...this item can bring you online and show you when your door has been opened, closed, and how long the door has stayed open for an allotted amount of time. You can also, if you choose to set up the LED w/ 470 ohm resistor, change the LED state with a couple of website search commands. For instance, 192.168.7.2:5000 is what you would type to get to your Flask application. Then, if you wanted to turn on your LED with this software, you would type 192.168.7.2:5000/ledLevel/100. This will turn your LED on to full power.
Oh and I found this example from a book, "Getting Started with BeagleBone," by Monk. He typed up this book in 2014.
The software should show you exactly how to set up your machine for production.
