{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status:**\nThe refrigerator is operating within normal parameters, consuming an average of 553.06W with a total energy consumption of 560.02 kWh over the 51-day monitoring period.\n\n**2. Key Metrics Summary:**\n*   **Current Load:** 553.3W (224.4V, 3.28A).\n*   **Efficiency:** Average Power Factor (PF) of 0.72.\n*   **Operational Health:** 98.83% EN50160 voltage compliance.\n*   **Cost Estimate:** Total consumption to date is approximately 61,602 PKR (@ 110 PKR\/kWh).\n\n**3. Notable Observations:**\n*   **Overload Events:** The device registered 1,313 \"OVERLOAD\" readings. Given the max power spike of 2,562.4W, these incidents likely represent compressor start-up surges rather than persistent electrical faults.\n*   **Voltage Stability:** While overall compliance is excellent, 585 voltage sags were recorded. These fluctuations may impact the longevity of the compressor motor; monitoring for further degradation is advised.\n*   **Efficiency:** A PF of 0.72 suggests moderate inductive load efficiency; ensure the cooling coils are cleaned regularly to prevent the compressor from working harder than necessary.","cached_at":"2026-08-28T15:41:43+05:00","expires_at":1787914003}
