I'm assuming they're all just variations on VEDirect, right? Power the Lynx w/ 5V externally, and then use the remaining 2 cables for TX & RX. I'm just not sure if an RPi w/ Venus OS is equipped to do anything with that information.
It's REALLY a shame that literal life saving data is restricted to a forced purchase of another $300+ device just for communication. I am using a SmartShunt & a RPi w/ Venus OS. I would really like to be notified if one of my fuses blow.
