This tutorial will explore how to use ESP32 with the Favoriot platform. Favoriot is a cloud-based Internet of Things (IoT) platform that allows users to connect and manage their IoT devices, collect and analyze data, and trigger actions based on data events. ESP32 is a powerful, low-cost Wi-Fi and Bluetooth-enabled microcontroller widely used for IoT applications.

By combining the capabilities of ESP32 with the Favoriot platform, we can create powerful IoT applications that collect, analyze, and act upon real-time data from connected devices. In this tutorial, we will demonstrate how to send data from an ESP32 board to the Favoriot platform using HTTP POST requests and the Arduino IDE.

We will also discuss how to customize the JSON payload to include different types of data and how to interpret the response codes from the API requests. By the end of this tutorial, you will understand how to use ESP32 with the Favoriot platform to build your own IoT applications.

Look at the example code below:

[/et_pb_text][et_pb_text _builder_version=”4.20.4″ _module_preset=”default” background_color=”#e5e5e5″ global_colors_info=”{}”]

#include <WiFi.h>
#include <HTTPClient.h>

const char* ssid = “your_SSID”;
const char* password = “your_PASSWORD”;

void setup() {
Serial.begin(9600);
delay(1000);

// Connect to WiFi network
Serial.print(“Connecting to “);
Serial.println(ssid);
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println(“Connecting to WiFi…”);
}

Serial.println(“Connected to WiFi”);

// Send data to Favoriot platform
sendDataToFavoriot();
}

void loop() {}

void sendDataToFavoriot() {
// Create an instance of HTTPClient
HTTPClient http;

// Set the API endpoint URL of Favoriot
String url = “https://apiv2.favoriot.com/v2/streams&#8221;;

// Set the headers of the HTTP request
http.addHeader(“Content-Type”, “application/json”);
http.addHeader(“apikey”, “YOUR_API_KEY”);

// Create a JSON payload to send
String jsonPayload = “{\”device_developer_id\”:\”ESP32_Device\”,\”data\”:{\”temperature\”:25.4,\”humidity\”:65}}”;

// Send the HTTP POST request
int httpResponseCode = http.POST(url, jsonPayload);

if (httpResponseCode > 0) {
Serial.print(“HTTP Response code: “);
Serial.println(httpResponseCode);
Serial.println(http.getString());
} else {
Serial.print(“Error code: “);
Serial.println(httpResponseCode);
}

// Free resources
http.end();
}

In this code, replace the ssid and password variables with your WiFi credentials, and replace YOUR_API_KEY with your Favoriot API key. The sendDataToFavoriot function creates an HTTP POST request to send data to Favoriot platform. The JSON payload in the example contains a device ID, temperature and humidity data, but you can customize it according to your use case.

Note that this is just an example code and there may be additional steps required to set up your ESP32 board and install the necessary libraries in the Arduino IDE.
