Agreed. I'm sure many of the differences are station dependent, and some stations may have a separate monthly & annual rain channel; however, as you noted, I don't see why monthly and annual rain aren't available for graphing with my old Davis Weather Monitor II since I have the rain gauge and both monthly and annual totals are displayed in the Year over Year stats, and with other tags.
Waiting now on comment from Stu. If he misses this thread, I'll send it to the support address or Stu directly.
Thanks for your help.
