{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status:** The refrigerator is operating efficiently within normal parameters, with a total consumption of 502.16 kWh over the 45-day monitoring period.\n\n**2. Key Metrics:**\n*   **Current Load:** 569W (Voltage: 227.3V, PF: 0.75).\n*   **Historical Average Power:** 551.48W.\n*   **Voltage Quality:** 98.66% compliance with EN50160 standards.\n*   **Operational Health:** 95.7% uptime (41,793 active readings vs. 637 off).\n*   **Cost Estimate:** Total energy cost is approximately 55,237 PKR (at 110 PKR\/kWh).\n\n**3. Notable Observations:**\n*   **Overload Events:** The device logged 1,206 overload events, which is disproportionately high compared to \"OFF\" states. This suggests the unit may be struggling during startup cycles or experiencing frequent compressor stress.\n*   **Voltage Stability:** The system is stable, showing no swells, though 585 voltage sags were recorded. \n*   **Efficiency:** The average power factor (0.7196) is relatively low, indicating potential reactive power losses that could be optimized to improve motor efficiency.\n*   **Recommendation:** Investigate the cause of the high number of \"OVERLOAD\" readings to prevent premature compressor failure.","cached_at":"2026-08-22T15:46:49+05:00","expires_at":1787395909}
