access AD2USB via Python on Windows

[kapios]

I have a working AD2USB connected to my Vista 20P, successfully monitored using the Windows keypad app.
I would like to use Python so that I can also trigger different actions based on zone faults BUT I am not able to access the AD2USB. When I run the "usb_detection.py" script from GITHUB I get an exception: "No AD2USB devices present".
I have restarted the program, the PC etc but I can not get anywhere.

Please, any help would be appreciated. Thank you!

Are you by chance using the keypad app at the same time? The device can only be opened by one app at a time. If you want more code to be able to connect at the same time then run the ser2sock code inside of the GUI app or on a Raspberry pi.

That being said I have not tested this on Windows but I put it on my list today to tinker with.

I do have the keypad app closed when I try to run the python script. Also, I would assume that the error code would be different if there was a port conflict. For some reason it does not see the device at all.

Unfortunately I don't have a Raspberry pi to try accessing the AD2USB - it does look like the webapp may be able to do the things that I need but I figured I can get Python on Windows to accomplish the same.

Please let me know if there is anything that I may be overlooking after you have had a chance to try it on Windows.

Thanks.

I have not been able to make any headway on this. If anyone has been successful using python on windows to get zone tracking, I would appreciate any pointers.

Away from python, is there any other way to programatically monitor zones or trigger actions based on zone changes using the ad2usb? I prefer staying in a windows environment.
