Sensors added but no value seems received / interpreted

[Enbata]

Hi everybdy,
I am new to both mysensors and Vera but I managed to add my serial gateway to the veralite and my two sensors (connected to the same arduino) are detected and successfully added. But I don't receive any data on the vera.
When i monitor the sensor serial port, everything seems to be OK:
send: 1-1-0-0 s=0,c=1,t=1,pt=7,l=5,st=ok:44.0
H: 44.00
send: 1-1-0-0 s=1,c=1,t=0,pt=7,l=5,st=ok:13.0
T: 13.00

But in Veralite UI, I just see my temperature and humidity sensor with no value (the temperature one only displays "Temperature" and no value, humidity one displays nothing).
Anybody has an idea to:

• monitor Vera serial port directly from ssh on vera ?
• what's happenning on my Veralite ?
  My firmware of vera is: 1.6.641
  In addition, first time I used the device created by the mysensors plugin, I could launch include mode but now i can't since all buttons have disappeared.
  Thanks for your answers

Making a SSH connection to Veralite i managed to see the LuaPNP.log and found that a xml file had been corrupted and was not found anymore. Now everything works fine !
