Many appliances, homes, and buildings consume more energy than they need, leading to energy waste and higher costs. Shelly 3EM is a smart, professional three-phase energy meter that helps you monitor energy consumption in real time and receive alerts when a device or system consumes more energy than a preset limit. You can also control protection.

365-day data storage and proactive monitoring – Shelly EM measurements are stored in the free cloud for 365 days. When an electrical device is damaged, it not only stops working, but its energy consumption also typically increases. Shelly 3EM Power Monitoring immediately detects an increase in power consumption and notifies you, so you don't have to spend extra money on repairs or replacements.

Solar panel monitoring and smart, efficient car charging – Monitor how much energy your solar panels and wind turbines are generating and saving. Shelly 3EM is designed for single-, two-, or three-phase monitoring and allows you to track your vehicle's status and history, as well as its current and historical energy consumption.

With the SHELLY SMART CONTROL app, you can remotely control your Shelly devices and receive notifications about all automated events in your home. You can easily configure devices and manage their settings individually, or create personalized scenarios by combining Shelly devices to trigger specific actions within your home automation system.
