Phil,

A while back I found this hack for arne.c

It worked for me.

**************************************************************************

Here is a dirty hack. arne.c around 292 line ...

  sprintf(buffer,

"%2.1f %2.1f %2.1f %2.1f %2.1f %2.1f %d %d %3.3f %3.3f %3.3f %3.3f %2.1f
0.0 0.0 %4.4f 0.0 0.0 0.0\r\n",

    ...
    (wd->rain >= 0.0F) ? 0.01F * (float)
                                 (wd->rain_count - wd->rain_offset[7]) :
    wd->RH[0],  /* Humidity in % */
    wd->barom[0]/33.864 /* Barometer in inHg */
                         );

Just filling humidity and barometer is enough.
