button below 
This blueprint is designed for practical day/night operation:
- Night: exactly one watering at a fixed time
- Day: repeated watering with interval changes based on weather conditions
- Adaptive timing: all timing values are derived from one normal watering profile
- Safety gap: prevents watering too frequently
How weather affects watering interval:
- High sun states: sunny, clear, clear-night
- Low sun states: cloudy, fog, hail, lightning, lightning-rainy, pouring, rainy, snowy, snowy-rainy, windy, windy-variant, exceptional
- Medium sun: all other states (including partlycloudy)
Main inputs:
- Weather entity
- Last watering helper (input_datetime)
- Night watering time
- Normal watering duration
- Normal interval
- Multipliers for low sun, high sun, night duration, and safety gap
- Start/stop watering actions (for pump control)
Suggested defaults:
- Normal duration: 300 seconds (5 minutes)
- Normal interval: 120 minutes
- Low sun multiplier: 1.5
- High sun multiplier: 0.4
- Night duration multiplier: 0.5
- Safety gap multiplier: 0.17
