I'm a beginner, some simple flow I've already created and working on.
Now I would like to read data from the RS485 power meter concentrator. The data is loaded into a string that has 83 bytes. Data is in hex. Is here everything is OK.
I need to split the individual bytes from the string and save them to separate variables or array.
For example, four bytes from Byte (position) 11:
var NewArrayValue1 = msg.payload.string(11,4);
I read the forum, but I can not catch anything from which I would bounce off. Would you be nice and could I ask for advice? Thank you
