 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.

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.
