    "product": "Shelly 3EM-63T Gen3 is a smart energy meter for monitoring three-phase systems or three single-phase circuits. It features 4-quadrant measurement, real-time data with optical pulse indication, Accuracy Class B, photovoltaic system support, and easy integration into smart home or professional setups. Precise Measurements & Data Logging : Measures voltages from 220-240 V AC and currents up to 63 A per phase, with built-in data storage for up to 7 days at 1-minute intervals Home Energy Management - The device helps homeowners monitor and optimize energy use with real-time insights into appliance or circuit consumption. It identifies high-usage devices, supports efficient scheduling (e.g., for heating/cooling), and enables local automation to cut power during peak times-reducing costs without sacrificing convenience. Cost Optimization for Businesses - The device lets businesses monitor energy use across three circuits, enabling precise tracking of machines, departments, or processes. This helps identify inefficiencies, allocate costs accurately, and reduce overhead through data-driven operational improvements. Solar Energy Monitoring - Ideal for PV system users, the device tracks both energy production and consumption to ensure peak solar performance. It helps align usage with generation, enabling tasks like EV charging during peak sunlight to reduce grid reliance and maximize renewable energy benefits.",
