Hello,
I got Venus OS running on an RPI4. I am about to receive my VE.Direct cable tomorrow to hookup to my Victron MPPT solar controller and start seeing it there and in VRM. I thought it would be simply plug to USB on RPI and MPPT, but I read on the Venus OS wiki that I need to power this cable on both ends ?
Not sure I understand that USB usually provides the power itself so why do I need to provide separate power to it ?
Thanks in advance
