Everything you need to establish a basic communication with an UPS via Python code.
This project started in February 2020 and ended in March 2020 due to lack of interest. So I decided to publish the code, hoping it can be useful for other people.
The UPS Communication Class (ups_comunication_class.py) works pretty well, but it lacks a perfect error checking, and needs a lot of improvements.
The low level packet generator (jbus.py) is working without problems and has been tested for many hours continuously.
Before uploading the project to GitHub I added a lot of comments. I hope I haven't damaged anything on the code, but if so, these are errors that can be easily solved.
