This project aims to replace the existing thermostat of a G3 Ferrari Pizza Oven with an ESP‑chip based control system, thereby improving precision, responsiveness, and overall temperature regulation.

Happy baking! 🍕🛠️

Prerequisites

Item	Description
ESP‑32 Dev Board	Any WiFi‑enabled chip with at least 4 GPIO pins will do
MAX6675 K‑Type Thermocouple	Only a K‑type thermocouple can withstand the temperatures required
5V Relay Module	Atleast 10A
Power Supply	5V / 2A AC-DC adapter
Connecting Wires	Silicone heat resistant wiring

Clone the Repository

git clone https://github.com/vincvdwal/crust-craft/
cd crust-craft

The repo contains the following layout:

Installing PlatformIO

VS Code Extension

Open VS Code.

Go to Extensions → Search for “PlatformIO IDE” → Install. Restart VS Code → PlatformIO panel appears on the left.

Project Configuration

Open the project:

Platform Command VS Code Double‑click crust-craft folder or open > File → Add Folder to Workspace.

Edit platformio.ini (shown below – you can adjust as needed):

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino

; Optional environment for ESP8266
[env:esp8266]
platform = espressif8266
board = nodemcuv2
framework = arduino

Building the Firmware

Click the “Build” icon (checkboard) in VS Code’s PlatformIO toolbar. The output will be displayed in the Build Log pane. Success → you’ll see: Build Done and an firmware.bin file under .pio/build.

Uploading to the ESP via VS Code

Press “Upload” (right‑hand arrow icon) in the PlatformIO bar → It will compile (again if necessary) and flash to the device.

Serial Monitor

Click the “Monitor” icon (plug + arrow) or Ctrl+Alt+M

Custom Configuration – Wi‑Fi Credentials

The firmware stores your Wi‑Fi SSID & password in secrets.h.

Copy the example or create a new file

cp src/secrets.example.h src/secrets.h

And replace the following with your Wi-Fi credentials

// Replace with your network credentials
const char *ssid = "WIFI_SSID";
const char *password = "WIFI_PWD";

Installing the filesystem
