Hello,
I am looking to build a system that monitors (read only) the status of four SmartSolar 75/15 MPPT controllers and a BMV-712 and uses the data to make decisions on power use by other systems. Data required to be monitored would be charger mode (float/bulk/absorption) and power output from each MPPT controller plus battery voltage and SOC from the BMV.
I would prefer to go with the Arduino platform as I am familiar with it, in particular the ESP32 with Bluetooth support.
It appears to my novice view that I cannot talk to the Victron devices using Bluetooth and that I will instead have to use wired serial communications, one to each device. Is this correct or is it possible to monitor the devices for the data I need using Bluetooth?
Matt
