{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operational and stable, maintaining 100% voltage compliance despite frequent overload events.\n\n**2. Key Metrics Summary**\n*   **Current Load:** 529.7W (3.27A) at 236.4V.\n*   **Performance:** Average power draw is 572.81W with a low average Power Factor (PF) of 0.72.\n*   **Consumption:** Total energy recorded is 87.01 kWh, with a cumulative cost impact of approximately 9,571 PKR over the observation period.\n*   **Reliability:** 100% EN50160 voltage compliance (0 sags\/swells).\n\n**3. Notable Observations**\n*   **Overload Frequency:** The device recorded 281 \"OVERLOAD\" states. Given the max power spike of 2562.4W (significantly higher than the 529.7W current draw), this suggests frequent high-inrush current during compressor start-ups or potentially undersized equipment for the load.\n*   **Power Factor:** The PF (avg 0.72) is sub-optimal. The low efficiency indicates inductive load stress, which may lead to higher utility billing if the restaurant is subject to PF penalties. \n*   **Uptime:** The system is consistently active, with only 7 recorded \"OFF\" events over the 7-day period.","cached_at":"2026-07-15T11:21:09+05:00","expires_at":1784096769}
