The serial driver receives data from the Chargery BMS and can be used with Venus OS. The serial driver is coded in Python and grabs the data form the RS232 USB interface every second. Example Images:

Requirements

• Chargery BMS
• FTDI Adapter FT232RL USB TTL Serial (IMPORTANT: Must be flashed with FT_PROG software to invert tx mode)

Optional

• Support for Victron Venus OS. Support is enabled with the "--victron" command line parameter

Installation

• TBD

Command Line Parameters

  -h, --help            show this help message and exit
  --version             show program's version number and exit
  --debug               enable debug logging
  --test                test some stored examples network packets
