Start simple. Water if moisture dips below a percentage, open shade when lux exceeds a ceiling, and avoid rapid toggling using timed buffers. These foundations provide stability that machine learning can later refine without undoing months of dependable, confidence building behavior.
Weather services reveal cloud cover, wind bursts, and expected heat that drive evaporation and leaf stress. Use this horizon to pre water before heat waves, or extend shade minutes ahead of glare, maintaining comfort and moisture with minimal intervention throughout demanding days.
