Shelly Pro 3EM 120A v2

Shelly PRO 3EM 120A 3-Phase Electricity Meter with WiFi/Bluetooth/MatterThe Shelly Pro 3EM 120A is a professional, three-phase electricity meter designed for DIN-rail mounting. The device reports accumulated energy with 1% accuracy, as well as instantaneous voltage, current, and power for each phase in real time. It stores data from the last 60 days at one-minute intervals for each phase, enabling detailed analysis. It can operate standalone on a local LAN and/or Wi-Fi network, or be managed via a home automation cloud service using MQTT, HTTP, and WebSocket protocols. Furthermore, thanks to its scripting feature, it allows for the creation of advanced scenarios and offers extended monitoring options. The device is also compatible with the Matter standard, making it even easier to integrate into selected smart home systems.
