CrustCraft
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
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
Use NPM to install all packages used for the website
npm i
Developing the filesystem
For developing the FS you can use the following command:
npm run dev
Building and flashing the filesystem
Create the ESP‑FS image
npm run build
This command writes all of your web assets (HTML, JS, CSS) into a data/ directory
Upload the image to the ESP32
In the PlatformIO toolbar, hit "Build Filesystem Image" to pack the data/ dir into a flashable filesystem image.
Afterwards, click "Upload Filesystem Image" to send the image to the chip.
OTA Updates
The firmware can also be updated over the air. Once the device is connected to your local network, navigate to its IP address (e.g., http://192.168.1.50/update). On that page you’ll find an upload form for the firmware binary, and another for the filesystem image. Simply select the new files and click Upload; the ESP32 will flash them via Wi‑Fi.

ToDo
Display
- Add capacative LCD screen to be used in addition to the WebSocket connection for direct control on the oven
- Maybe add sensor to indicate if the lid has been opened
