It would be interesting put rain and wind sensitivity functions in the individual irrigation zone.
For example, in my system, each area is exposed differently to the sun, to the wind and to the rain (e.g. zone 1 and 2 terrace, full sun, partial wind and full rain, zone 3 balcony, partial sun, partial wind and medium rain, zone 4 rear balcony full sun, full wind and poor rain).
