{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status:**\nThe refrigerator is operating consistently with an average load of 550.65W, though it exhibits significant power fluctuations and intermittent overload states.\n\n**2. Key Metrics Summary:**\n*   **Total Energy Consumed:** ~395.34 kWh (approx. 43,487 PKR cost).\n*   **Operational Power:** Avg 550.65W (Range: 1.6W \u2013 2562.4W).\n*   **Power Factor:** 0.74 (Current) \/ 0.72 (Avg), indicating moderate efficiency.\n*   **Voltage Quality:** 233.3V (Current) with 98.23% EN50160 compliance.\n*   **Uptime:** 31,517 Active readings vs. 622 OFF states.\n\n**3. Notable Observations:**\n*   **Overload Frequency:** The unit recorded 995 \"OVERLOAD\" events. Given the 2562.4W peak, these spikes are significantly higher than the average draw, suggesting potential compressor strain or starting-current surges that warrant technical inspection.\n*   **Voltage Stability:** While overall compliance is high, 585 voltage sags were recorded. These fluctuations may be contributing to the inefficient Power Factor (0.72), which is below the ideal unity threshold.\n*   **Efficiency:** The low PF suggests reactive power waste; consider installing a capacitor bank or checking for motor degradation to reduce operational costs.","cached_at":"2026-08-12T12:48:39+05:00","expires_at":1786521219}
