Product description: Shelly 3EM - 3-phase energy meter
Shelly 3EM is used to measure energy for each of the three phases, but it can also be connected to single- and two-phase installations, as well as to the solar power supply. The module has been adapted for installation in the electrical switchboard using a standard DIN rail. It communicates with the WiFi network, allowing for a remote viewing of the current energy consumption using the appropriate application.
The device cooperates with Shelly Cloud application, which works in Shelly Cloud and other APIs such as: MQTT, HomeSeer, OpenHAB, Home Assistant, iBroker, REST, Hubitat, HOOBS, SYCON, Domoticz, nymea.
Shelly 3EM main features
- Wireless communication - Shelly 3EM can be connected to any WiFi network or act as an access point.
- Remote Controlled - The ability to remotely view your current power consumption using applications and Shelly Cloud, MQTT or other APIs.
- Wide compatibility - Shelly 3EM is compatible with Android and iOS.
- Security - the device will automatically switch off when the power consumption threshold is exceeded.
- Schedule - in the application you can set a daily schedule for the device to work.
- Protection against power theft - a real-time view allows you to see the current consumption for each phase.
- Single-phase systems - Shelly 3EM can also monitor single-phase electrical installations with up to 3 points simultaneously.

Year-round measurement history
Shelly 3EM meter allows you to get the measurement history from 365 days in a CSV file. The device exports a file with the history from the day, week, month or year in a 5-minute time interval. This information allows you to analyze your electricity bills. All data is also saved in the cloud at increasing intervals.
History of energy consumption measurements.
Shelly 3EM energy meter connection
Before installing the unit, make sure that the circuit is unplugged. Three sensors are included to measure the current in the circuit. Below is a diagram of how to connect the meter for 1 / 2 / 3 phases.
