A compact energy meter designed to monitor either a three-phase system or three independent single-phase circuits. It integrates seamlessly into smart home or commercial systems, providing accurate real-time data for optimizing energy efficiency.

Key Features:

• 4-quadrant measurement.
• Multiple connection types: three-phase or single-phase installations.
• Measurement via built-in current transformers.
• Phase sequence error detection (optional).
• No load limit.
• Visual pulse indicator of energy usage.
• Real-time clock with storage for correct time offsets.
• Data records: up to 7 days of data for later retrieval.
• Accuracy Class B (IEC 62053-21).
• Photovoltaic ready.

Short Description:

The Shelly 3EM-63 Gen3 is a compact energy meter that monitors three-phase systems or independent single-phase circuits. It can operate autonomously on a local Wi-Fi network or via MQTT, HTTP, and WebSocket services. It supports TLS for all incoming connections.

The device reports accumulated energy and instantaneous voltage, current, active and apparent power per phase in real-time, stores the data in non-volatile memory, and can be retrieved for a period of up to 7 days at 1-minute intervals. It features a real-time clock for accurate time if the connection to the SNTP server is lost.

The device can be monitored and configured remotely by the user and has a built-in web interface for control and settings.
