Shelly PRO 3EM 120A WiFi Dual-Channel Electric Energy Meter

The Shelly Pro 3EM 120A is a professional three-phase electric energy meter that can be installed on a DIN rail. The device reports accumulated energy with 1% accuracy as well as real-time voltage, current, and power for each phase. It stores data for the last 60 days with a resolution of one minute for each phase, enabling precise analysis. It can operate independently on a local LAN and/or Wi-Fi network or be controlled via a home automation cloud service using MQTT, HTTP, and WebSocket protocols. Furthermore, it offers advanced scripting capabilities and extended monitoring options.
