-===== 6. References =====+===== 6. Optional Energy-Aware Operation ===== 
 + 
 +  * AOFS controllers **may** measure power consumption of pumps, valves, and other actuators while running.   
 +  * Controllers **may** estimate battery drain or energy availability for upcoming scheduled irrigation events.   
 +  * AOFS supports **event prioritization**: 
 +    * Each scheduled irrigation or actuator event can be assigned an **urgency or importance level** by operators.   
 +    * If insufficient energy is available: 
 +      * Low-priority events can be **delayed or skipped**.   
 +      * High-priority events are executed **as soon as sufficient energy is available**.   
 +      * Optional alerts notify operators of skipped or delayed events.   
 +  * AOFS can provide **proactive scheduling guidance** (optional): 
 +    * When the operator attempts to schedule an irrigation or actuator event, the system **may simulate expected energy usage and availability**.   
 +    * The controller can then **warn the operator**: "Based on current energy estimates, you will most likely not have enough power for this event."   
 +    * Operators may then adjust **priority, timing, or load** before committing the schedule.   
 +  * All energy measurements, prioritization decisions, and resulting operational logs **may be recorded** for later analysis: 
 +    * Enables visualization of energy usage and event execution history.   
 +    * Helps operators determine if additional batteries, solar panels, or load rescheduling are needed.   
 +  * Optional anomaly detection: 
 +    * Alerts operators if an actuator consumes more power than expected (e.g., clogged pipe, stuck valve). 
 + 
 +===== 7. Manual Fallback Mode ===== 
 + 
 +AOFS supports **manual fallback operation** for farms without fully automated actuators.   
 + 
 +  * **Purpose:**   
 +    * Ensure irrigation and critical farm operations can continue when automatic valves or pumps are unavailable.   
 +    * Maintain safety, compliance, and event logging even with manual operation.   
 + 
 +  * **Operation:**   
 +    * Field Controller generates **step-by-step instructions** for operators: 
 +      * Which pump to switch on/off.   
 +      * Which valve to set to open/closed or partial position.   
 +      * Timing recommendations based on **irrigation schedule, soil moisture, tank levels, and weather conditions**.   
 +    * Operators must **confirm completion of each step** in the controller interface.   
 + 
 +  * **Logging & Documentation:**   
 +    * All manual actions **must be logged**: 
 +      * Operator ID   
 +      * Action taken (pump/valve)   
 +      * Timestamp   
 +      * Relevant sensor readings at the time (tank level, flow, battery voltage, etc.)   
 +    * Logs are synchronized with Farm/HQ controllers whenever connectivity is available.   
 + 
 +  * **Benefits:**   
 +    * Allows farms to **comply with AOFS even with low-tech equipment**.   
 +    * Ensures operators follow optimized schedules and safety procedures.   
 +    * Enables full **auditing and analytics** later when automation is introduced.
