Shelly Pro 3EM – Accurate 3-Phase Energy Meter with WiFi
The Shelly Pro 3EM is a compact energy meter for 3-phase networks, communicating via WiFi, Bluetooth, and Modbus. It measures energy, active power, apparent power, voltage, and current up to 63 A and is designed for DIN rail mounting.
Measures consumption per phase and provides precise data to optimize electricity costs
Versatile interfaces: WiFi for cloud connectivity, Bluetooth for local configuration, and Modbus for building automation integration
Compact DIN rail design – fits into any distribution board without wasting space
Unlike simple plug-in energy monitors, the Pro 3EM measures directly in the distribution board and captures all three phases simultaneously. The combination of WiFi, Bluetooth, and Modbus allows easy setup via the app as well as professional integration into existing smart home or building management systems.
Ideal for...
The Shelly Pro 3EM is aimed at homeowners, electricians, and facility managers who want to monitor the energy flow of an entire building or individual circuits in detail. It is especially suitable for applications that require per-phase measurement and remote monitoring.
How to use the Shelly Pro 3EM
Mount the device on a DIN rail in the distribution board. Connect the 230 V power supply and the current transformers to the phases to be measured. Configure the device via the Shelly app or web interface and connect it to your WiFi network. The recorded data can then be viewed in the app, via MQTT or Modbus.
