VE.Direct library for Rust

Library to parse the Victron Energy "VE.Direct" protocol and map the data to useful structs with clear units.

Can be used in conjuction with the serial library to pull battery status information from devices like the BMV 700, or solar charging data from the Victron's various MPPT solar charge controllers.

Details

Developed using a VE.Direct to USB interface cable to a BMV 700, cross compiled for the connected Raspberry Pi Zero W.

Based of the VE.Direct-Protocol-3.27.pdf.

Currently only implements the "Text-mode" (read only) interface,

The VE.Direct interface includes two modes: Text-mode and the HEX-mode. The purpose of the Text-mode is to make retrieving information extremely simple. The product will periodically transmit all run-time fields. The HEX-mode allows not only to read data but also write data, for example, change settings.

Status

Early development.

• Initial protocol parser
• Initial mapping of most useful BMV 700 fields
• More complete testing of parser
• Mapping of all fields of BMV
• Mapping of all fields for MPPT
• Mapping of all fields for inverters
