BoilerSaver (ESP32)

This example is a larger real-world project based on the ConfigurationsManager library. It combines runtime controls, sensor input, optional MQTT integration, and Web UI configuration.

What it demonstrates

  • Complex settings structure with grouped pages/cards
  • Runtime actions and live values (/runtime.json, /runtime_meta.json)
  • Optional MQTT defaults via src/secret/secrets.h
  • Integration of external components (e.g. OneWire/DallasTemperature, OLED)

How to run

From the repo root:

pio run -d examples/BoilerSaver -e usb
pio run -d examples/BoilerSaver -e usb -t upload

First start / AP mode

If no SSID is configured yet, the device starts in AP mode. Open the printed AP URL from Serial (usually http://192.168.4.1) and configure WiFi via the Web UI.

Optional secrets defaults

You can copy src/secret/secrets.example.h to src/secret/secrets.h and set default WiFi/MQTT credentials.
