I noticed after switching Wunderground reporting from my GW1000 to Cumulus that "rain rate" is being reported differently. The GW1000 reports the actual rain rate, but Cumulus reports accumulated rain over the past 60 minutes as the "rate". After doing some googling, it seems like Wunderground's upload specifications call for reporting rain rate as Cumulus report it. But I much prefer the rain rate to match the value reported by the GW1000.
Would anybody else be interested in an added option in the Wunderground settings to control which version of the rain rate is uploaded?
