For Fixed schedules, a connected rain sensor serves to make the Iro skip any waterings that would have occurred while the rain sensor remains active (while it is still drying out), right?
For Flex schedules, I assume the rain sensor does essentially the same thing: prevents the Iro from watering while it is active.
However, I also assume that the rain that triggered the sensor is not accounted for in the Flex schedule. I guess the watering is delayed rather than skipped, in this case. Even though the waterings are delayed, the evapotranspiration data has not, so the Iro doesn’t know to recalculate. (I guess this assumes that the weather station data would have been off and your property received rain when none was observed at the selected weather station).
Is all that correct?
Is there any way to use a rain sensor as a poor man’s weather station and assume some amount of rain (configurable by the user, to match the setting on the sensor) in the Flex calculations?
If not, is there any benefit to a rain sensor when running only Flex schedules?
