I have a new uninstalled BMV712 with BT and SmartSolar MPPT 150/70. I plan to use my phone/BT to see what is going on for charging, capacity, etc.
What purpose would connecting them both via a VE direct cable do? Would I gain any additional information? Do the two devices talk to each other over the VE or is this via Bluetooth?
I.e. should I buy a long VE cable and connect them?
