Hi Scott,
is everyone that is having the problem have the setting for WD set to include the unit of measure?
That was it! I watched it change from the snow icon to the rain then found the place in WD for the setting, unticked it and let it update. The icon changed over to snow after the update. For anyone setting up the testtags.txt, make sure the Include units in replaced tags is unticked. I am not sure if it defaults ticked but mine was and it seems to have fixed this problem. I will watch to make sure but feel confidant that it's fixed! Thanks Scott for all the help and for the great dashboard!
Steve
