Fork from winginitau/VictronVEDirectArduino to change to a non blocking reading approach.
Lightweight Arduino library to read data using the VE.Direct protocol from Victron Energy devices
Built as part of a larger project, now making it available separately in case others find it useful.
Setup:
- An Arduino(ish) board
- A Victron Energy device that sends serial data using the text version of the VE.Direct protocol
- For BMV products : A 5v to 3.3v serial converter (BMV is 3.3v - don't plug it directly into a 5v Arduino!)
- Plugged into the Arduino on a serial port (eg Serial1, Serial2, Serial3 etc)
- See also: https://www.victronenergy.com/live/vedirect_protocol:faq
- Distributed under an MIT license - see LICENCE.txt
Provides:
- Read access to VE.Direct statistics and settings
- Defaults set to read Volts, Power, Current, State of Charge (SOC), Alarm
- Easily extendible by adding labels for any other stats and settings of interest
- A diagnostic "full dump" of everything coming from the device
