Hello, I have a K868 A16 card, I would like to use it for photovoltaic.
I followed the procedure to load the BIN file from Kincony, I control the card and I created actions via IFTT.
Unfortunately, I haven't found the source file for your BIN so I can modify the file and reinject it as if it were an Arduino IDE ESP32.
I would have liked to be able to define variables to memorise the state of the battery in charge/discharge, the sun producing more, ...
Not having to use a Raspberry pi, pc ...
Will the RS485 port be able to include the battery BMS and will the board alone be able to extract the data and process the values?
Is it possible to connect a small screen displaying messages via I2C?
How can I add the program via the Arduino IDE without losing the original BIN file?
I'd like to use a voltage divider bridge, connect the voltage of the photovoltaic panels and the battery voltage so that the board controls the starting or stopping of the inverter depending on the amount of sunlight and the state of charge/discharge of the battery.
I'm thinking of using conditions via IFTT because I'd like the card to work locally if the internet isn't working.
I was thinking of using ESPHOME and HA, but if there is no internet the card will be useless I suppose.
Thanks for your help.
