I have 2 MPPT's (see link below) hooked up to a Raspberry Pi running VenusOS. One is working like a charm, but the other one is not sending data through the VE.direct to usb cable.
I already tried using a VE.direct to bluetooth dongle, and that seemed to work. I got correct and realtime data.
Apart from that, i also tried a brand new cable. This one also didn't work.
Can someone help me fix this?
