Smart 3-Phase Energy Meter with Contactor Control.
Many appliances, homes, and buildings use more energy than they need, leading to energy waste and higher spending. Shelly 3EM is a smart 3-phase professional energy meter that will help monitor electricity usage in real-time and get notified in case an appliance or system consumes power above a pre-set threshold. Additionally, it allows for contactor control Smart energy metering will help you identify and eliminate any redundant energy consumption. 

Functionalities:

• Wi-Fi Operated: Connect Shelly 3EM to your Wi-Fi network. No HUB required!
• Power Monitoring: Shelly 3EM monitors monophase electrical systems with up to 3 points simultaneously. 
• Contactor control: Shelly 3EM has an integrated relay with a rated current of 10A per output for contactor control.
• 365 days of data storage: The measurements from Shelly 3EM are stored in a free cloud for 365 days.
• Custom schedules: Set custom schedules based on a daily agenda or working hours. 
• Smart scenes: Set custom scenes by combining Shelly 3EM with your other Shelly devices.

Full compatibility.
Shelly devices are compatible with Alexa, Google Home, Android and iOS. Together with the voice assistant, you can command Shelly devices using just your voice! 

Shelly Smart Control.
Shelly Smart Control is here! One app to control your spaces, energy consumption, and expenses. 

Use cases:
Preventative monitoring.
When an electrical appliance is damaged, it doesn't simply stop working. Usually, it increases the amount of energy used in an attempt to compensate for its operational capacity. Since there is no visible difference in its performance, it might take months before you can identify a problem, leading to inefficiency and wasted energy. Shelly 3EM power monitoring will immediately read the increase in energy consumption and will notify you, saving you additional expenses on repairs or replacement of equipment.

Solar panels monitoring and control.
Keep track of how much energy your solar panels and wind turbines are generating and save effortlessly. Shelly 3EM provides real-time information about the efficiency of the solar and wind energy system, as well as historical data on how much energy has been generated and consumed. This helps you control the energy flow, getting the most out of your solar panels and wind turbines. To take it a step further, connect a contactor to Shelly 3EM, so you can switch off automatically non-essential devices in your home, in order to save energy.

Smart and efficient car charger.
Shelly 3EM is developed to monitor one, two, or three phases and allows you to monitor the status and history and the current and past electrical power consumption of each separate channel for the day, week, month, or year. Shelly 3EM exports all data in CSV format in 10-minute intervals, making data analysis and cutting back costs easy. That way, you can monitor the exact energy your electric car consumes and calculate what part of your electricity bill it forms.

2-way energy consumption monitoring.
Monitor your home, office, or factory, and avoid additional expenses or drops in voltage that can damage your appliances and devices. Shelly 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate circuits of a mono-phase electrical system and control a contactor. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor.
