In my current configuration I unfortunately can't get the rain sensor to work.
Construction as follows:
OpenSprinkler 3.2 - AC
Firmware 2.1.9 (7)
A2D adapters:
Sensor 1 - rain sensor (RSD-BXE) (GND+SN1) - potentiometer middle position - does not switch at all regardless of the position of the potentiometer
Sensor 2 - soil moisture (SMT-50 GND +SN2 + VIN) - pot adjusted and soil moisture - works fine
