At this year's use phase has been found that the Soil Moisture Sensor always 'dry' displays in slightly moist soil and any sensitivity adjustment (corresponding with LNKS-stop. 0). This means that is also irrigated with automatic watering when the soil is still moist enough. 'Resolve' to let this behavior only if you had convinced of the soil moisture and sufficient and has poured in the immediate vicinity of the Soil Moisture Sensor half a jug of water in the soil, so that this again was wet and then 'wet' indicating and so that the automatic irrigation prevented.
Conclusion: The Soil Moisture Sensor is not sensitive enough for the unobserved operation, because it can be applied to a still sufficient residual moisture in the soil is not set and this only as trocken'erkennt 'and then turn on the irrigation. This not only increases the sales of Gardena but also the water supply. But does not suit me!
PS .: It may be possible to compensate for the lack, if the sensor is placed in a location that is hard to dry out according to experience. But that's not the whole point.
