## Smart Zone Calculator

Integration that will calculate watering zone runtime given:

- Calculated ETO requirement sensor (mm)

- Rain over period sensor (mm)

- Watering throughput of the zone (mm/h)

- Zone scale factor (%)

- Max zone run time (mins)

Calculations as follows:

```

delta = rain over period - calculated ETO requirement

if delta < 0 then

    # Watering required

    runtime = abs(delta) / throughput * 3600 * scale factor (seconds)

    if (reqd * 60) > max zone run time

        runtime = max zone run time * 60

else

    runtime = 0

```
