Had 0.4 inches of rain yesterday, immediately after which my scheduled “Smart Watering” irrigation started! I do not have a rain sensor, so rely on integration with the weather report rain prediction.

The system does delay (not irrigate) when rain prediction is greater than 50% but rainstorms are spotty, quick, and not reliably predicted in my tropical south Florida climate even if they are very heavy. What is needed is for the rain delay to kick in if there has just been heavy rainfall in the area, not only if rain is predicted.
