Product information

Description

Shelly Pro 3EM is a three-phase energy meter with Wi‑Fi connectivity designed for monitoring electrical consumption and managing loads in residential and commercial installations. The device measures voltages and currents on all three phases, calculates active and apparent power, and provides real‑time and historical usage data via a web interface and compatible automation platforms. Its compact DIN‑rail form factor and direct integration options enable installation inside distribution boards for centralized energy oversight and load balancing.

Advantages

The Shelly Pro 3EM offers simultaneous measurement of three-phase voltages and currents with high update frequency, enabling accurate power and energy readings. Built‑in Wi‑Fi connectivity allows remote monitoring and configuration without additional gateways. The device supports alerts and threshold-based notifications, integration with common home and building automation systems, and local data logging for historical analysis. Its design fits standard electrical panels and supports straightforward wiring for three-phase systems.

Suitable for

  • Residential multi‑phase houses and apartments with three-phase supply
  • Commercial premises requiring consumption monitoring and billing transparency
  • Small industrial installations and workshops for load management
  • Building automation systems seeking real‑time energy data integration

Key specifications

  • Measurement: three‑phase voltage and current monitoring
  • Power metrics: active and apparent power calculation and energy accumulation
  • Connectivity: Wi‑Fi for remote access and integration with automation platforms
  • Form factor: DIN‑rail mount suitable for electrical distribution boards
  • Data features: real‑time measurements, historical data logging, and threshold alerts
  • Installation: direct connection to three‑phase lines with standard wiring practices

How to use

Install the Shelly Pro 3EM inside a compatible distribution board on a DIN rail and connect the three phase conductors and neutral according to the wiring diagram supplied by the manufacturer. After powering the device, use the web interface or the Shelly configuration app to connect the meter to the local Wi‑Fi network, set measurement intervals, and configure thresholds or notifications. Integrate the meter with your home or building automation platform using supported APIs or protocols to view real‑time data and historical consumption. Verify current and voltage readings after installation and adjust settings for data retention and alerting as needed.

Usage recommendations

Perform installation and wiring only by a qualified electrician and follow local electrical codes. Place the meter in an environment within the specified temperature and humidity ranges, protect it from direct water exposure, and ensure secure Wi‑Fi connectivity for reliable remote monitoring and data synchronization.
