Details

Shelly EM is Shelly's single phase power meter for recommended for both home and corporate use. Shelly ЕМ can monitor energy consumption in real time in 2 points simultaneously (up to 120A each). With Shelly EM you can also measure how much energy your solar system produces and the power consumption at the same time.

365 day built-in energy history.
We developed Shelly ЕМ to allow you to monitor the status and history, as well as the current and past electrical power consumption for the day, week, month or year.

Small size full of functionalities: Intelligently designed to fit in most standard electrical boxes and switches. Shelly EM is smaller than  cookies stacked together.

It can automatically turn off the whole circuit if consumption or energy (pre-paid energy option) reaches the set limit and has integrated relay output made for contactor control.

Detailed info about electricity consumption: With Shelly EM, you can view the quality of your energy network regarding active power, reactive power, voltage, and power factor. Monitor your facility or home to avoid additional expenses or drastic drops in energy that may damage your appliances and machines.
