{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operational and compliant with voltage standards, though it shows signs of frequent electrical stress.\n\n**2. Key Metrics Summary**\n*   **Current Power:** 555.9W (Avg: 564.6W)\n*   **Total Energy Consumed:** 172.73 kWh (approx. 18,995 PKR cost)\n*   **Efficiency:** Average Power Factor (PF) of 0.71 indicates moderate reactive power loss.\n*   **Voltage:** Stable at 228.5V (within 215.7V\u2013249V range); 100% EN50160 compliance.\n\n**3. Notable Observations**\n*   **Overload Concerns:** The device recorded 397 \"OVERLOAD\" states, suggesting the compressor or motor may be drawing excessive current during start-up or due to mechanical strain.\n*   **Operational Consistency:** The refrigerator is almost constantly active (13,528 active readings vs. only 17 off), which is expected for a restaurant environment, but the high number of overload events warrants a mechanical inspection to prevent premature failure.\n*   **Power Factor:** A PF of 0.71 is suboptimal; consider capacitor maintenance if the unit has power factor correction hardware.","cached_at":"2026-07-22T15:24:30+05:00","expires_at":1784716170}
