Set up Favoriot

Create the device that will represent each monitored tire and collect the credentials the firmware needs.

1. Sign up or log in at platform.favoriot.com
2. Go to Device Management > Devices > Add Device, name it tireMonitor01, set Device Type to General, then save and copy the Device Developer ID
3. Navigate to Settings > Account and copy your API Key

Connect the sensors

Wire the temperature and pressure sensors to the NodeMCU.

Upload the Arduino code

Reads both sensors every ten seconds and streams the values to Favoriot over HTTPS.

#include <ESP8266WiFi.h>
#include <DHT.h>
#include <ESP8266HTTPClient.h>

#define DHTPIN D4
#define DHTTYPE DHT22
DHT dht(DHTPIN, DHTTYPE);

const char* ssid = "YOUR_WIFI_SSID";
const char* password = "YOUR_WIFI_PASSWORD";
const String apiKey = "YOUR_FAVORIOT_API_KEY";
const String deviceDeveloperId = "tireMonitor01";

void setup() {
  Serial.begin(115200);
  delay(100);
  dht.begin();

  WiFi.begin(ssid, password);
  Serial.print("Connecting to WiFi...");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("\nConnected to WiFi!");
}

void loop() {
  float temperature = dht.readTemperature();
  int pressureRaw = analogRead(A0);
  float pressure = map(pressureRaw, 0, 1023, 0, 100); // Simulate PSI

  if (WiFi.status() == WL_CONNECTED) {
    HTTPClient http;
    http.begin("http://apiv2.favoriot.com/v2/streams");
    http.addHeader("Content-Type", "application/json");
    http.addHeader("apikey", apiKey);

    String payload = "{";
    payload += "\"device_developer_id\":\"" + deviceDeveloperId + "\",";
    payload += "\"data\":{";
    payload += "\"temperature\":" + String(temperature, 2) + ",";
    payload += "\"pressure\":" + String(pressure, 2);
    payload += "}}";

    int httpCode = http.POST(payload);
    Serial.print("Favoriot HTTP response code: ");
    Serial.println(httpCode);
    http.end();
  } else {
    Serial.println("WiFi not connected!");
  }

  delay(10000); // 10-second interval
}

Set up the Favoriot dashboard

Turn the incoming stream into something a driver or fleet manager can actually read at a glance.

Create these from Dashboard > Add Widget: select the device, choose the data fields, and set the ranges that define normal for your tires.

Alert notification via Telegram

Close the loop so an out-of-range reading reaches a person, not just a database.

1. Create a Telegram bot: search @BotFather in Telegram, run /newbot, give it a name and username, and note the bot token
2. Get your chat ID: start a chat with your new bot, then visit https://api.telegram.org/bot<your_bot_token>/getUpdates to find it
3. Set up the webhook in Favoriot under Rules Engine > Add Rule

From this point on, whenever tire conditions turn unsafe, the driver gets a Telegram notification, in the moment it matters rather than after the fact.
