WHY SHELLY EM?

SMART ELECTRICITY METER WITH CONTACTOR CONTROL

Shelly EM is a Wi-Fi powered electricity meter with contactor control. It allows you to simultaneously monitor the consumption of any household appliances, circuits, and office equipment (lighting, power lines, security systems, heating, cooling, etc.) in 2 circuits on the same phase or individually. Shelly EM is perfect for measuring solar power production and monitoring household consumption as well as controlling higher load devices.

Endless application possibilities

POWER CONSUMPTION ANALYSIS FOR COST OPTIMIZATION

All connected electrical devices that we do not use at night, or accidentally left-on lights, consume unnecessary energy. Smart energy measurement helps you identify and eliminate redundant energy consumption from any connected device in your home or facility.

HEAVY-DUTY CONTROL WITH CONTACTORS

In addition to precise power measurement, Shelly EM enables contactor control of high-performance devices such as powerful water heaters, whirlpools, heat pumps, and energy-intensive kitchen appliances. This way, you can both monitor and control the consumption of such devices in your home or facility and maximize your savings.

MONITORING AND CONTROL OF SOLAR PANELS

Track how much energy your solar panels and wind turbines generate and save effortlessly. Shelly EM provides real-time information on the efficiency of your solar and wind energy system as well as historical data on how much energy was produced and consumed. This helps you control energy flow and get the most out of your solar modules and wind turbines. To take it a step further, connect a contactor to Shelly EM so you can automatically turn off devices in your home that you don’t necessarily need to save energy.

TOTAL POWER MONITORING

With Shelly EM, you know how much energy your home consumes! Shelly EM is the perfect solution for single-phase homes and can significantly improve your energy-saving efforts by constantly monitoring the total power in your fuse box and giving you immediate control over your electricity usage. Connect a contactor to Shelly EM and save energy by automatically turning off all devices you don’t necessarily need.

PREVENTIVE MONITORING

When an electrical device is damaged, it doesn’t just stop working. Usually, it increases energy consumption to compensate for its operating capacity. Since there is no visible performance difference, it can take months before you notice a problem, leading to inefficiency and energy waste. However, Shelly EM immediately reports the increase in energy consumption, saving you additional repair or replacement costs.
