Read your home electricity meter’s pulse LED with an ESP32 and ESPHome, then send real-time power and total kWh to Home Assistant. This guide covers optical sensor setup, pulse_meter configuration, conversion from imp/kWh to watts and kWh, Energy dashboard integration,…
Turn a basic pulse-output water meter into a fully local Home Assistant sensor using an ESP32 and ESPHome. This guide shows wiring, pulse_meter setup, live flow rate, total consumption, Energy dashboard integration, daily and monthly usage tracking, and simple leak-detection…
This example shows how to read touch coordinates from an STMPE610 resistive touch controller using I²C or SPI. The sketch detects touch events, reads X/Y/Z pressure data, and prints everything to Serial for debugging and calibration. The STMPE610 is a…
This example shows how to control 8 LEDs using the PCF8574 I²C GPIO expander with an ESP32. The sketch cycles through each LED by sinking current through the expander pins, demonstrating how the PCF8574 works and why wiring matters. The…
This example shows how to use the Adafruit nRF8001 Bluetooth Low Energy breakout in callback mode. The sketch starts advertising, reports connection events over Serial, receives incoming BLE UART data, prints it, and immediately echoes the same data back to…
