  Hello,
  
  writing in English if of common interest.
  I’m using the Aurora Arduino Library that runs very well : thank-you and congratulations.
  I would like now to share the RS485 connection also some other Modbus devices (well running), still on the same RS485 line, of course with different Modbus Ids, using (if possible) one only ModbusMaster istance and MAX485 on Software serial.
  Unfortunately the configuration seems to be imcompatible, and if I start calling Aurora (e.g with Aurora::DataState dataState = inverter.readState()) the MODBUS data flow stops.
  There is no method Aurora.end neither that can help in switching-off Aurora when Modbus call starts.
  
  Do you have any suggestion ?
  Grazie molte per ogni aiuto, saluti

  Hello,
  
  I have solved the issue by myself, simply moving in the main loop() the alternate call to :
  
  pzemSerial.begin(9600); //Baud Rate as 9600… sopra sembra non farcela
  node.begin(slaveID, pzemSerial)
  
  and after :
  
  inverter.begin();
  
  …
  
  It works very well
  Thank-you
  Best regards
  Ugo
