I have a ET112 energy meter, a RS485 to USB (serial) cable and a cerbo GX. What is the serial baud rate (9600 ??, 115200 ??) the cerbo uses over the USB serial connections ?.
CONTEXT: the ET112 and the Cerbo are remote, and I am building my own device to connect the USB serial on the ET112 side to the USB serial on the cerbo side.
I know about the zigbee adaptors, but do not want to use those.
