{"response":"**1. Overall Energy Status**\nThe main refrigerator is operating with a high duty cycle, consuming 335.2 kWh over the 30-day period at an average power of 554.45W.\n\n**2. Key Metrics Summary**\n*   **Operational Health:** 96.3% uptime (26,025 active readings vs. 616 off).\n*   **Efficiency:** Average Power Factor (PF) is 0.725; current load is 573.9W.\n*   **Voltage Quality:** 97.88% EN50160 compliance; 585 voltage sags detected.\n*   **Cost Estimate:** Based on 335.2 kWh, the approximate monthly expenditure is 36,872 PKR.\n\n**3. Notable Observations**\n*   **Overload Frequency:** The device recorded 980 \"OVERLOAD\" states. With a maximum power spike of 2562.4W, the compressor may be experiencing frequent high-torque startup currents or potential mechanical strain.\n*   **Power Factor:** A PF of 0.73 is relatively low, suggesting the motor may require maintenance or the installation of a capacitor bank to improve electrical efficiency.\n*   **Stability:** While voltage compliance is generally good (97.88%), the 585 recorded sags indicate grid instability that could impact the long-term reliability of the refrigerator\u2019s control board. Monitoring for premature compressor wear is advised.","cached_at":"2026-08-07T12:28:20+05:00","expires_at":1786088000}
