The CircuitSetup Split Single-phase Energy Meter is an affordable, accurate, remote energy monitoring device for your entire home. It can monitor energy usage in real time, independent of your power utility’s meter, and can be easily hooked up to any wireless micro-controller (like an ESP8266, or ESP32) to transmit energy data into a program like EmonCMS. It can also be used to monitor solar systems to keep track of how much power you are generating from the sun. It uses safe current transformer clamps to sample current - no AC wiring is required. https://elecena.pl/product/16994405/circuit-setup-energy-meter-board 2020-06-27 https://elecena.pl/product/16994405/circuit-setup-energy-meter-board 2020-08-04
