a um tempo fiz esse codigo porem nao estou conseguindo tanto passar quanto recuperar dados do firebase se alguem puder me ajudar

#include <ESP8266Firebase.h>
#include <ESP8266WiFi.h>

#define _SSID “iPhone de Nicolas” // SSID da sua rede WiFi
#define _PASSWORD “NIK#2005” // Senha da sua rede WiFi
#define FIREBASE_HOST “https://agua-e6f2c-default-rtdb.firebaseio.com/” // Host do Firebase
#define FIREBASE_AUTH “H6ozqosjqNeTVJZJ3ks25ih73ZaRu0ongOCq6zQm” // Token de autenticação obtido após configurar a autenticação no Firebase

Firebase firebase(FIREBASE_AUTH);

void setup() {
Serial.begin(115200);
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, LOW);
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(1000);

// Conecta ao WiFi
Serial.println();
Serial.println();
Serial.print("Conectando a: ");
Serial.println(_SSID);
WiFi.begin(_SSID, _PASSWORD);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(“-”);
}

Serial.println(“”);
Serial.println(“WiFi Conectado”);

// Printa o endereço IP
Serial.print(“Endereço IP: “);
Serial.print(“http://”);
Serial.print(WiFi.localIP());
Serial.println(”/”);
digitalWrite(LED_BUILTIN, HIGH);

// Examples of setting String, integer and float values.
// firebase.setString(“Example/setString”, “It’s Working”);
//Serial.print(firebase.setInt(“/valor/carro”, 123));
//firebase.setFloat(“Example/setFloat”, 45.32);

// Examples of pushing String, integer and float values.
// firebase.pushString(“push”, “Hello”);
//firebase.pushInt(“push”, 789);
//firebase.pushFloat(“push”, 89.54);

// Example of getting a String.

// Example of getting an int.
//int data2 = firebase.getInt(“/Teste/valor”);
// Serial.print(“Received Int:\t\t”);
//Serial.println(data2);

// Example of getting a float.
// float data3 = firebase.getFloat(“Example/setFloat”);
// Serial.print(“Received Float:\t\t”);
// Serial.println(data3);

// Example of data deletion.
// firebase.deleteData(“Example”);
}

void loop() {
// Nothing
String data1 = firebase.getString(“aiai”);
Serial.print(“Received String:\t”);
Serial.println(data1);
delay(10000);
