{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status:** The refrigerator is operating within stable parameters with excellent power quality, consuming approximately 89.53 kWh over the past week at an average load of 530.06W.\n\n**2. Key Metrics Summary:**\n*   **Power Usage:** Average 530.06W (Range: 480.4W \u2013 655.9W).\n*   **Voltage:** Stable at 232.31V average (Range: 215.5V \u2013 242.4V).\n*   **Efficiency:** Average Power Factor (PF) of 0.705.\n*   **Compliance:** 100% EN50160 compliance with zero sags or swells.\n*   **Operational Cost:** Weekly consumption cost is approximately 9,848 PKR (based on 110 PKR\/kWh).\n\n**3. Notable Observations:**\n*   **Power Factor:** The PF (avg 0.70) is relatively low, indicating potential inefficiencies in the motor\/compressor system. Improving this could reduce reactive power losses.\n*   **Stability:** The device shows high electrical reliability with zero voltage disturbances. \n*   **Anomalies:** The system recorded 2 \"OVERLOAD\" instances; while negligible compared to 9,558 active readings, these should be monitored if they increase in frequency to prevent compressor strain.","cached_at":"2026-09-14T17:34:40+05:00","expires_at":1789389580}
