Protection against invalid values #27
Description
Twice in three weeks I've seen total surface precipitation values that make no sense. One had a historical sum of 2862.941544 kg/m^2, the other had a whopping 178907691.31199998 kg/m^2. These values completely destroy precipitation vs. evaporation calculations, so will disable the sprinkler system even if it should be enabled.
We should have some validation for inbound data so invalid data can be discarded.
