Estou com Problema com a minha ESP8266 (ESP01s) com o DHT22

Estou com problemas ao ativar um relé, eu estou utilizando esse sensor para quando a temperatura estiver maior que 30 ele ative o relé, além disso também estou utilizando a biblioteca adafruit para mostrar a temperatura e acionar o relé. Contudo mesmo aparecendo os dados do sensor no adafruit eu não consigo acionar usando a comparação do "if". Preciso de ajuda urgente!

Programação:
#include "config.h"
#ifdef ARDUINO_ARCH_ESP32

#else

#include "DHT.h"

// digital pin 5
int returnu = 0;
int returno = 0;
#define DHTPIN 2
#define LED_PIN2 0
#define DHTTYPE DHT22
DHT dht(DHTPIN, DHTTYPE, 15);
// button state

// set up the 'digital' feed
AdafruitIO_Feed *digital1 = io.feed("temperatura");
AdafruitIO_Feed *digital2 = io.feed("umidade");
AdafruitIO_Feed *digital3 = io.feed("ventilador");
AdafruitIO_Feed *digital4 = io.feed("teste1");
AdafruitIO_Feed *digital5 = io.feed("teste2");

Start with the posted sketch, especially loop(), the DHT dht.readTemperature() call, the tempe > 30 condition, and digitalWrite() on LED_PIN2. Reproduce it on the ESP8266 with the DHT22 and relay while watching the serial output; the finished behavior should consistently activate the relay above 30°C and deactivate it otherwise.
