Yup. Got a September 1 Seasonal Shift message as I was hand-watering to save landscaping on the hottest day ever reported in NorCal. Good idea, poor implementation. Rachio can access plenty of data sources to prevent such errors. In this case, a "local shift" should be applied to the seasonal shift.
In any case, this first happened August 1, then again today. I'm disabling all automatic schedule adjustments til next year, perhaps they'll have an update by then.
