Shelly 3EM relay switch for indirect measurement of power consumption, Wi-Fi network. The 3EM relay switch can be used to measure power consumption from three channels, and the device is also able to calculate two-way consumption (produced/used). Three current transformers (max 120 A) are included. In indirect measurement, the accuracy may suffer if the size of the transformers deviates significantly from the electricity consumption.

With the Shelly 3EM relay switch, you can monitor the consumption of 3 separate devices or the main interface (3-phase). Works great via Shelly Cloud for various remote control and consumption monitoring.

Fairly easy to install, current transformers around the wires, but requires a visit from a professional electrician.

In the future, it will work with the Woltti service and you can use the system to optimize the use of electricity in accordance with, for example, the Spot price
