Hi,
I will explain my experience.
This morning my raspberry, where I installed 123Solar, it didn't communicate with my Power One inverter .
So I tried with putty to run the command:
szttyDevice: /dev/ttyUSB0
yDelay: 1
yTimeout 0 mS
yMaxRunTime ~

This morning my raspberry, where I installed 123Solar, it didn't communicate with my Power One inverter .
So I tried with putty to run the command:
aurora -a 2 -c -T -Y4 -d0 -e /dev/ttyUSB0
and I have received the error:
aurora: ERROR: Received bad return code (-1 0)
After that I tested the communication with the command:
aurora -a 2 -b -e /dev/ttyUSB0
and it returned:
aurora -a 2 -b -e /dev/ttyUSB0szttyDevice: /dev/ttyUSB0
yDelay: 1
yTimeout 0 mS

So I googled to looking for someone met the same error and I find out a post in a forum where someone have suggested to change the parameter Y from -Y4 to -Y10.
The parameter Y means:
-Y
After the changing it looked works but after a while it stopped.
At the end I discovered that a wire was disconnected in the converter RS-485 to USB! I fixed it and now it works!
Bye
Francesco

Anche se è un post vecchio, la tua soluzione mi ha "salvato" non sapevo dove sbattere la testa ;-)
Grazie!
