Shelly Pro 3EM 120A is a professional three-phase electricity meter that can be installed on a DIN rail. The device reports stored 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, allowing for accurate analysis. It can work independently of a local LAN and/or Wi-Fi or be controlled via a cloud-based home automation service using MQTT, HTTP and WebSocket protocols. In addition, it offers advanced scripting capabilities and advanced monitoring capabilities.
