my MPPT 250/100 seems to have lost connection to the venus OS (2.89). The initial connection via VE.Direct-to-USB cable has worked. I think I messed around with DVCC settings and disabled it again. Since then the MPPT was first "disconnected" and has disappeared from Venus after rebooting the RPi.
There was a message about resetting VE.Direct, but I cannot find any instructions. What do I need to do to ?
