Finally finished my home energy monitor project this afternoon. This uses the infrared port of my Elster R1S hydro meter, read by a repurposed Blueline Innovations PowerCost Monitor sensor. The R1S meter outputs a 100ms wide IR pulse for every 1mWh or energy consumed. Home Assistant uses the ESPHome pulse meter platform to convert these pulses into both power (pulse rate) and energy (pulse counts) readings. The ESP32 fit nicely into a repurposed Raspberry Pi case. #homeassistant #esphome
