The Shelly Pro EM-50 is an advanced Wi-Fi energy monitor that transforms how you track and manage electrical consumption in your home, business, or industrial settings. Featuring a dual-channel, single-phase energy meter, it provides precise real-time measurement and reporting of total energy consumption, voltage, current, as well as active and apparent power.

Reliability and Safety

Equipped with the latest second-generation firmware technology and LAN/Wi-Fi connectivity, the Shelly Pro EM-50 offers operational flexibility and reliability. It can function independently within a LAN or Wi-Fi network and can be integrated with home automation cloud services using MQTT, HTTP, and WebSocket. All incoming connections are secured with TLS protocols ensuring data security.

Complete Energy Monitoring

This device monitors total energy consumption, voltage, current, active, and apparent power in real-time. Data is stored in non-volatile memory and can be accessed up to 60 days later, with recordings at one-minute intervals, allowing users to track and analyze energy usage for informed energy management decisions.

Easy Setup

The Shelly Pro EM-50 allows remote access and configuration, easily integrating with home automation systems within the same network infrastructure. It comes with a built-in web interface for convenient custom settings management. The user-friendly interface simplifies device configuration and monitoring.
