Shelly EM is a Wi-Fi-operated Energy Meter with Contactor Control. It allows you to simultaneously monitor the consumption of any home appliances, electric circuits, and office equipment (lights, power lines, security systems, heating, cooling, etc. ) in 2 circuits on the same phase or individually.
Shelly EM is perfect for measuring solar energy production & consumption at the same time, monitoring household consumption, and controlling heavier-load appliances.
It can automatically turn off the whole circuit if consumption or energy (pre-paid energy option) reaches the set limit and has an integrated relay output made for contactor control.
Two independent measuring channels up to 120A each
One contactor control (or load up to 2A)
365 days of internal memory in case Wi-Fi is not available
Voltage measurement and configurable alarm reporting.
Precise power meter with 1% accuracy, 50A and 120A current transformers are available (sold separately)
User-friendly charts
Detailed report downloadable in CSV
