Shelly Pro 3EM - three-phase energy meter WiFi Bluetooth

Shelly Pro 3EM is a new generation 2-way three-phase energy meter. It reports in real time the accumulated energy as well as the instantaneous voltage or power factor for each phase. The meter offers an extraordinary measurement accuracy of up to 1% and stores data for up to 60 days . The module is enriched with advanced scripting functions that allow you to set non-standard scenes and guarantee wide monitoring possibilities. It can work with photovoltaics, and after appropriate programming, your devices will automatically reduce their energy consumption. The counter is compatible with other Shelly devices. It is mounted on a DIN rail and is equipped with WiFi, LAN and Bluetooth connectivity.
