There are two moisture values: the top soil moisture reported by the sensor, and the overall soil moisture estimated by Netro. We have a AI model to estimate the overall soil moisture.
The smart watering uses overall moisture level. We checked the smart watering is set to customize with a low of 25% and a high of 45%, which is the overall moisture level so it does not match with 6% moisture level which is the sensor moisture level.
You can go to Settings->Sensors->Select a sensor and tap the "Watering Adjustment" to input the value of "moisture to skip watering/ add watering". This skip watering feature use the top-soil moisture from Whisperer sensor, not the overall moisture level.
