Hi @landru, Emil here, filling in for Kevin.
You nailed it!
I pulled your weather stations and there appears to be some reporting issues with the PWS. For reference the two reporting stations are:
PWS (Personal Weather Station) + Reports
NWS (National Weather Station)
As you can see, the temperate reported by the PWS never changes.
I'd recommend we use the NWS until v2.0 of the app released, in which you will be able to choose the exact weather station you would like our cloud API to use when determining rain delay, water budgeting, and tracking weather (evapotranspiration) for flex schedules. We will display a map with national and personal weather stations including all the data you need to make the right choice on which station is right for you (distance, etc.). For more information, please see this announcement
Hope this helps.
