{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status:**\nThe refrigerator is operating within normal parameters with stable voltage quality and high operational reliability.\n\n**2. Key Metrics Summary:**\n*   **Current Power:** 501.2W (Avg: 529.77W)\n*   **Energy Consumption:** 101.36 kWh (Total period)\n*   **Cost Estimate:** ~11,150 PKR (based on 101.36 kWh @ 110 PKR\/kWh)\n*   **Voltage:** 229.9V (Avg: 232.48V)\n*   **Power Factor:** 0.70 (Avg: 0.704)\n*   **Compliance:** 100% EN50160 (0 sags\/swells)\n\n**3. Notable Observations:**\n*   **Performance:** The unit is highly stable, maintaining 100% voltage compliance over the 8-day observation period.\n*   **Efficiency:** The Power Factor (PF) is consistently low at 0.70. While typical for refrigeration compressors, this indicates reactive power losses that could be optimized with capacitor correction if energy costs rise further.\n*   **Anomalies:** There were 2 recorded \"OVERLOAD\" events. While statistically negligible (out of 10,828 readings), these should be monitored to ensure they do not correlate with compressor startup spikes or potential mechanical stress. \n*   **Operational Health:** The narrow power variance (480W\u2013656W) suggests consistent duty cycles.","cached_at":"2026-09-15T16:01:42+05:00","expires_at":1789470402}
