Shelly Pro 3EM Next-generation DIN-mountable 3-Phase Energy Meter

Shelly Pro 3EM is a DIN rail mountable three-phase energy meter. Enhanced with all the gen2 firmware flexibility and LAN connectivity, it provides professional integrators with additional options for end-customer solutions. Shelly Pro 3EM reports accumulated energy as well as instantaneous voltage, current, and power factor per phase in real time.

Shelly Pro 3EM is a Wi-Fi-operated DIN-mountable 3-Phase Energy Meter with Wi-Fi, Bluetooth, and LAN connectivity. With active energy measurement accuracy of 1%, Shelly Pro 3EM can be used to monitor the consumption of any home appliances, electric circuits, and office equipment individually. It features 60 days of on-device historical data with a 1-minute resolution for each phase. Additionally, its scripting functionalities allow for the execution of complex scenes and provide broader monitoring abilities.

Shelly Pro 3EM supports mTLS for MQTT, HTTP, and secure outbound WebSockets. Its industry-grade security allows for direct connections to your cloud infrastructure, reducing the cost of deploying complex networks and VPNs.
