Generating a file only once per day is better suited to a simple cron task 
rather than weewx I suspect - and the cron task could also take care of any 
conversions and formatin issues for your data file.  It IS possible with 
weewx, but weewx is really more suited to regular reporting cycles rather 
than once per day.  

The conversion could be done by 
leafwetness = 255 - (17 * leafwetness)
