{"response":"**1. Overall Energy Status**\nThe refrigerator is operational with an average power draw of 552.98W, incurring an estimated cost of 69,484 PKR over the 57-day monitoring period.\n\n**2. Key Metrics Summary**\n*   **Total Consumption:** 631.67 kWh\n*   **Operational Efficiency:** Average PF of 0.72 (Range: 0.65\u20131.0)\n*   **Voltage Stability:** Avg 230.41V; 98.95% EN50160 compliance.\n*   **Duty Cycle:** Predominantly active (53,515 readings) with 649 \"OFF\" cycles.\n\n**3. Notable Observations**\n*   **Overload Frequency:** The device recorded 1,422 \"OVERLOAD\" events. Given the peak power reached 2562.4W (significantly higher than the current 492.2W), this suggests recurring compressor strain or startup surges that warrant a maintenance inspection.\n*   **Voltage Quality:** While compliance is strong, the 585 recorded voltage sags indicate instability in the local power supply, which may be contributing to the observed PF fluctuations and potential component stress.\n*   **Efficiency:** The low average Power Factor (0.72) suggests suboptimal motor performance; verifying the capacitor health is recommended to improve energy efficiency.","cached_at":"2026-09-03T16:14:31+05:00","expires_at":1788434371}
