Pizza Oven IoT

Merenel took part in the programming of both the web app and the chip for an ambitious and successful project that connected a great deal of pizza ovens to the cloud.

For a pizzeria manager, having an IoT oven connected to the Internet has several advantages:

• being able to take advantage of a tax credit equal to 20% of the investment for capital goods of industry 4.0
• see the status of the oven remotely in real time from any device
• enter the parameters of the cooking programs remotely
• analyze the engine rpm counters, valve opening, etc. and receive emails reporting wear of components
• receive email notifications about current alarms and any blockages
• have a larger screen to navigate and change settings more easily (plate rotation speed, extraction time, etc.)

In short, the 4.0 pizza chef will be much more up-to-date and will have complete management via PC, smartphone or tablet of: extraction times, cooking times and oven stand-by, and many other parameters (see the images below of the interfaces created by Merenel)

There are also numerous advantages for the manufacturer of a 4.0 oven who simply by opening the portal in the browser can:

• modify in-depth settings, such as the setting of the burner flame levels
• check if there are any alarms related to anomalies reported by the customer and provide targeted remote assistance
• release an improved firmware update
• check the customer’s license
• receive email notifications when the grease cartridge needs to be replaced or in-depth maintenance needs to be carried out on the gears

The oven has its own WiFi network that the user must connect to in order to enter the pizzeria’s WiFi credentials. Once the oven has memorized the WiFi credentials, it will immediately start communicating with the cloud.

The IT architecture includes:

• Server installed on ESP32 chip with Arduino firmware
• Dashboard created with Bootstrap from which you can see the data in real time and send remote settings (see the image gallery below)
• Data files of the counters and alarms in .csv format that can always be downloaded
• Script that sends automatic emails when predictive maintenance thresholds are reached
• MQTT broker with php script and Boostrap dashboard to send settings via the Internet from anywhere in the world
