I live in Katy Texas and have been using the Netro water controller in smart mode for over 2 years with no problems.  We received at least 1.5in of rain on the April 25, so I was dismayed to find my sprinkler system watering my yard on the morning of the 26th.  The rain graph in the app is showing 0.03in for the 25th and is clearly wrong.  I have tried changing to all the different weather providers, but the total rain accumulation doesn't change.  The frontal system that caused the rain passed over the entire area, so this is not a situation of local shower only affecting a localized area.
