The soil moisture reading displays on home page even without a sensor assigned. We just checked your account and we found the smart watering is every nine days in April, this this due to the rain. The default watering frequency is every 5 days and you can check it in Settings->Garden->Smart Zone->Estimated frequency and duration. However, the actual watering frequency and duration may vary due to weather. If you want to adjust the frequency and duration, you can change watering mode in Settings->Garden->Smart Zone->Mode.
