The project uses an ESP32-WROOM-32D to monitor my home energy using the current clamps from a Aeon labs Home Energy Meter, model DSB09104-zwus. The outputs of the current clamps and voltage reference are level shifted and buffered with op amps and sent to the ESP32 A/D. The code is Arduino using FreeRTOS and has no issues sampling the two currents and voltage reference at 1KHz, completing the calculations and sending them to Home Assistant using MQTT. See my github page at for more detail if interested.
