Library for interacting with UPB PIM.

Project description

Python UPB Powerline Interface library

Library for interacting with UPB PIM/CIM


  • Python 3.7 (or higher)


This package is created as a library to interact with an UPB PIM. The motivation to write this was to use with the Home Assistant automation platform. The library can be used for writing other UPB applications. The IO with the PIM is asynchronous over TCP or over the serial port.


    $ pip install upb_lib


Details TBD

Simplest thing right now is when in the root of the git repo that you have cloned is to enter the command bin/simple. You need the environment variable UPBPIM_URL set. Mine is set to serial:///dev/cu.KeySerial1 on a MacBook. What is constant is serial:// followed by the USB port that the PIM is on, which in my case is /dev/cu.KeySerial1. On Windows is might be something like COM1.

Also required is a UPStart export file. Mine is in the bin directory and named upb.upe. The simple program looks for it there.

This is all under very active development and will change. But if you really want to get up and running... Go for it!


This project uses poetry for development dependencies. Installation instructions are on their website.

To get started developing:

git clone
cd upb
poetry install
poetry shell # Or activate the created virtual environment
make test # to ensure everything installed properly

There is a Makefile in the root directory as well. The make command followed by one of the targets in the Makefile can be used. If you don't have or wish to use make the Makefile serves as examples of common commands that can be run.
