AlarmDecoder install (0) devices found

I bought the AlarmDecoder network appliance. Hooked it up and installed webapp and programmed keypad. Everything good.

Trying to integrate with SmartThings. Followed directions from Github https://github.com/nutechsoftware/alarmdecoder-smartthings
When I install SmartApp it says 0 devices found.

I’m new to this and learning, but stumped on this. Been searching for answer. Only thing I can think of is if I needed to edit code to devices before install?
