Would you mind DM’ing me your username or email address for the account? Alternatively screenshots are always great so we can see exactly what you’re seeing.
Our Rachio controller is reliant on the weather data being received from our third-party provider, Aeris, a global weather data source. In turn Aeris receives the information directly reported from the weather station.
If you’re finding that the weather forecast does not align with what your region is actually experiencing, I recommend revisiting your selection of weather stations and looking into nearby Personal Weather Stations (PWS). There may be a weather station closer to you with more accurate data.
If the data itself is incorrect, we’d need to open an investigation with Aeris.
Regarding your 2nd question, I am going to withhold and wait for the requested information above so I can directly analyze your account. The forecast data should be applied to all zones, however your individual zones may have different moisture balances and needs based off how you’ve configured them.
