{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operational and stable, consuming 322.87 kWh over the 29-day monitoring period with a healthy 97.79% EN50160 voltage compliance.\n\n**2. Key Metrics Summary**\n*   **Current Load:** 648.9W (3.62A) at 0.77 PF.\n*   **Aggregate Power:** Avg 554.11W (Range: 1.6W \u2013 2562.4W).\n*   **Efficiency:** Average Power Factor (PF) of 0.73 indicates moderate inductive load losses.\n*   **Voltage:** Stable average of 228.1V (Nominal 230V).\n*   **Total Cost Estimate:** ~35,516 PKR (based on 322.87 kWh @ 110 PKR\/kWh).\n\n**3. Notable Observations**\n*   **Overload Frequency:** The device recorded 979 \"OVERLOAD\" states. Given the 2562.4W maximum peak, verify if these spikes are normal compressor startup surges or indicative of mechanical strain.\n*   **Voltage Quality:** While compliance is high (97.79%), the system logged 585 voltage sags. Ensure the refrigerator\u2019s internal control board is protected against these fluctuations.\n*   **Uptime:** The device remained active for 97.4% of the monitored period (24,878 active vs. 615 off readings), which is consistent with standard high-use commercial kitchen requirements.","cached_at":"2026-08-06T13:05:36+05:00","expires_at":1786003836}
