Shelly EM is a Wi-Fi controlled energy meter with contactor control. It allows you to simultaneously monitor the consumption of household appliances, electrical circuits, and office equipment (lighting, electrical wiring, security systems, heating, cooling, etc.) in two circuits on the same phase or separately. Shelly EM is perfect for measuring solar energy production, monitoring household consumption, and controlling higher power devices.
