Why Shelly 3EM
The professional 3-phase energy meter.
Shelly 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate points of a mono-phase electrical system and measure each of them separately.
Shelly 3EM comes with a programming/debug header that can be used for flashing alternative firmware to the device. It has ESP8266 inside, with 4MB flash. A USB-to-UART adapter is needed as well as a reliable 3.3V power supply with at least 350 mA drive capability.
