-===== 5. Human Input / External Event Logging =====+==== Grid Power Monitoring & Predictive Use ==== 
 + 
 +**Purpose:** Enable AOFS to safely use intermittent grid power and optimize energy costs. 
 + 
 +**Required Measurements (if grid is available):** 
 +  * Grid voltage, current, and frequency 
 +  * Short-term fluctuations and harmonics 
 +  * Availability signal (on/off) 
 + 
 +**Optional Measurements:** 
 +  * Historical grid availability patterns 
 +  * Probabilistic prediction of grid power for upcoming hours 
 + 
 +**Integration & Control Logic:** 
 +  * AOFS must only allow grid power usage if parameters are within safe thresholds 
 +  * Automatic relays and actuators must cut off grid supply immediately on overvoltage, under-voltage, or unsafe frequency 
 +  * Predictive patterns can inform decisions, e.g., delaying high-load pump operations until grid is likely available 
 +  * All local safety thresholds remain authoritative and override probabilistic logic 
 + 
 +===== 5. Water / Water Energy Monitoring ===== 
 + 
 +**Purpose:** Monitor and optimize water supply sources, including grid water, local wells, and storage tanks. 
 + 
 +**Required Measurements:** 
 +  * Tank LOW and FULL levels 
 +  * Flow rate in main and zoned pipelines 
 +  * Flow rate and pressure of grid water supply (if available) 
 +  * Availability signal for grid water (on/off) 
 + 
 +**Optional Measurements:** 
 +  * Historical grid water supply patterns 
 +  * Probability of grid water availability in next hours or days 
 +  * Water quality indicators (salinity, turbidity) 
 + 
 +**Integration & Control Logic:** 
 +  * AOFS may delay pumping from wells if probability of grid water availability is high 
 +  * Partial tank fill strategies: maintain mandatory minimum levels locally, avoid overfilling if grid water is likely 
 +  * Safety thresholds for tank levels must always be enforced, independent of probabilistic logic 
 +  * Logging of decisions, sensor readings, and probabilities is required for learning and optimization
