Functions to communicate to Pylontech Batteries using RS-485 serial communication

3 Layer model - each can be used as lib:

  1. pylontech_base.py - Communication layer, RS485 to pylontech with raw frame support
  2. pylontech_decode.py and pylontech_encode.py for decodeing and encoding the frame content
  3. pylontech_stack.py high level abstraction for the whole stack. It iterates over batteries and calculates overall results and combines battery results to lists. Some detail information from layer 2 might not be implemented in this layer.

Installation using pypi.org:

  • run 'pip install pylontech-python'

build and Installation from source using pip:

  • build requires pip to be installed
  • run 'pip wheel -r requirements.txt' (installs e.g. pyserial) this downloads the required packages
  • run 'pip wheel .' this builds the wheel package
  • run 'pip install --force-reinstall ./*.whl' this installs the packages (both downloaded and build) --force-reinstall is used if you like to modify, rebuild and reinstall it.

Example: an example to use pylontech-python:

from pylontech import PylontechStack x = PylontechStack("/dev/ttyUSB0",baud=115200,manualBattcountLimit=5) x.battcount 2

A big "Thanks" to Daniel Schramm for his contibution!
