The Shelly 3em (mpn: 1012) is a smart, 3-phase electricity meter that allows you to monitor your consumption in real time. It notifies you when a device or system exceeds a predetermined value. With 3 independent measuring channels, each of which can measure up to 120a, you can keep an eye on everything. Furthermore, the electricity meter can calculate the energy flow in both directions - produced as well as consumed energy for each of the 3 phases. It also shows you the quality of your power grid by providing values for active power, reactive power, voltage and power factor. You will even be notified early on if your devices are broken or not working efficiently.

Contactor control - intelligent control for greater efficiency
This function acts like a smart switch that not only measures how much electricity you are using, but can also automatically switch large electrical devices in your home or business on and off. This allows you to save electricity and increase safety in your home or business at the same time. The electricity meter enables comprehensive home automation by allowing you to communicate with all your household appliances, work utensils or lighting via smart home systems.
Bidirectional consumption monitoring
You can monitor your energy consumption and production, avoid brownouts and prevent additional costs. The electricity meter measures the energy for each of the 3 phases and calculates both the energy consumed and the energy generated. In addition, it can monitor three separate circuits of a single-phase system and control a contactor. The Shelly 3em shows you the quality of your power grid in real time. Including active power, reactive power, voltage and power factor.
Solar panels and your system at a glance
With the electricity meter, you can easily track how much energy your solar panels are generating. It provides you with real-time information about your system, as well as historical data on the energy generated and consumed. This allows you to keep an eye on the energy flow at all times and maximize the performance of your PV system.
Preventive monitoring
A damaged electrical appliance often increases its energy consumption in order to continue functioning. This results in inefficient operation and wasted energy. Without visible signs, it can take months to notice the problem. The Shelly detects this early and notifies you as soon as possible. This can save you money on repairs or replacements.
Controlled viewing of data
With the 3em, you can track the current and past power consumption of each individual channel for the day, week, month or year. It exports all data in CSV format in ten-minute intervals, which simplifies your data analysis and cost reduction. For example, you can monitor and calculate the exact consumption of your electric car.
Full harmony and consistency
Shelly devices are compatible with Alexa, Google Home, Android and ios. So you can control everything simply by voice command. Download the Shelly Smart Control app from the App Store or Google Play.
