it sounds like you have set up wd for a station type with no humidity or smilar…
re check your station type settings…
its all OK here for me, and no other reports of this problem at this stage
also check your settings for the 1 wire settings in the com port setup…i.e that you have ticked, my normal station has a humidity sensor, and then restart wd…
i.e wd is just hiding that data thinking you dont have 1 (a 1 wire station does not normaly, you see)
