MPPT Solar Charge Controller Hack Part 1

[@JohnMeaking]

Hi Eric, Interesting video :-) Did I spot a second UART port on the display board? That might be worth a look! Keep up the good work.

Some controllers have optional RS485/Bluetooth/WiFi but you can inly have one. Maybe it has the port hardware, but not actual circuitry for it? Or perhaps it's just bespoke.
