Shelly 3EM-63W Gen3 WiFi Three-Phase Energy Meter with Integrated Current-Transformers

Introducing the Shelly 3EM-63 Gen3, a compact and versatile energy meter designed for both three-phase systems and three independent single-phase circuits. Whether you’re a homeowner enhancing your smart home setup or a professional seeking precise energy monitoring, this device is your perfect companion.

The Shelly 3EM-63 Gen3 offers flexibility, operating standalone in a local Wi-Fi network or integrating with cloud home automation services via MQTT, HTTP, and WebSocket. It provides real-time data reporting, including accumulated energy and instantaneous voltage, current, active, and apparent power for each phase, boasting Class B Accuracy (IEC 62053-21). Data is stored in non-volatile memory for up to 7 days, allowing detailed energy usage reviews in 1-minute intervals. The embedded web interface simplifies remote monitoring and control, while precise 4-quadrant measurement ensures accurate energy monitoring across all phases. Future-ready for solar integration, it tracks solar energy production alongside grid usage to optimise renewable energy strategies. The compact design makes installation easy and efficient.

This three-phase smart energy meter features innovative contactless metering with integrated current transformers, monitoring electric appliance consumption and reporting data to mobile devices or home automation systems. Shelly provides the flexibility to operate devices standalone or integrated with cloud home automation services, tailoring energy monitoring to individual needs. Internal data storage ensures easy retrieval and analysis of energy usage.

More than just an energy meter, the Shelly 3EM-63 Gen3 is a smart energy solution that empowers effective energy management. It offers precise measurement, simple installation, and future-ready capabilities, making it ideal for improving energy efficiency and sustainability.

Power Consumption Monitoring: Monitor the power consumption of connected devices in real-time. This information can be valuable for understanding energy usage patterns and making informed decisions to reduce consumption.

High accuracy: 4-quadrant measurement with Accuracy Class B (IEC 62053-21).

Energy Efficiency Optimization: Identify electrical energy consumption patterns and optimize electricity usage.

Appliance Health Check: Keep track of the power usage of individual appliances to assess their health and performance over time. Sudden spikes or changes in power consumption may indicate issues with the appliance.

Cost Management: With the knowledge of power consumption, you can estimate the cost of running specific devices and manage your electricity expenses more effectively.

Space-Efficient: The device is designed to slip over the breaker outputs fit seamlessly into your existing electrical box.

Remote Monitoring: Shelly 3EM-63 Gen3 supports publishing data to Shelly Cloud or other cloud-based data collection and storage systems. This allows you to monitor power consumption even when you're away from home.

Local Monitoring: Like the rest of the Shelly Wi-Fi line of devices, Shelly 3EM-63 Gen3 allows for local-only monitoring and automations. Access stored energy consumption records directly from the device UI. Automate locally with rules based on instantaneous power consumption or energy consumed over a period of time.
