This project is configured for an ESP32Dev board and a capacitive water sensor.
The water sensor is mostly in deep sleep. He awakes once every 10 min and stays awake until Prometheus queries its state.
Use PlatformIO to build and deploy
src/wlan.h set your local credentials here.
The IP is published via the Serial port, or check your DHCP server 🤯
The esp32 is configured to publish a webUI on port 80.
Here you can discover the current state and the Prometheus metrics data.
