MicroPython Energy Monitoring
summary
Australia uses about 900 PJ (≈250 TWh) yearly and household bills hide timing so a DIY meter helps. Uses an ESP8266/ESP32 running MicroPython/CircuitPython on Adafruit Huzzah and Lopy-style boards, an ADC plus a voltage transformer and a clamp-on CT to sample voltage×current and publish via MQTT/HTTP. Built a persistent room-temperature logger running a year; meter prototype reads mains pulses and per-second power but hit library and pin-mapping issues; cheap clamp is ~5% error whereas metering shunts or premium clamps reach ~0.5%.
