hi boris,
i´ve set up a rpi2 with the meteohub system to migrate from miy alix system. unfortunatly my davis vantage 2 has a rs232 interface. so i pluged in a rs232-usb converter. meteohub recognizes this as /dev/ttyUSB0 but there´s even another /dev/ttyMH113
i configured the vp2 with both possibilities but there seems no communication. here´s the log

i think that the converter doesn´t work, now i´ll try a 5V-3-3V-RS232-Serial-Port-to-TTL-Digital-Converter-Module-Max3232. could this work?
thanks in advance,
greeting

Question, did you use a usb hub?
See post viewtopic.php?f=56&t=10181&hilit=Usb+serial+converter

The different usb ports:
Usb0 is a logical software port address which can change after reboot.
The mh numbered ports are meteohubs way of addressing a physical port, which never change.

Therefor always select the mh numbered ports and mark the port the usb cable is connected into.

Success, wim

thx wim for your help.
no i didn´t use a hub. i plugged in the normal usb2rs232 converter. in the meantime i´ve attached and tried it with a 3232 IC via GPIO (see the latest thread). there, the communication between RPI 2 and VP2 seems to start, but then i get a timeout.
there even are some reported bugs, that were described here (wlan not functional, loosing gui), but i try to fix it step by step.

When plugging in the converter you should do "dmesg" if the module is recognized
as a USB-serial converter and then check "/dev/" directory to check if a serial device shows up.
