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

[iPakif]

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!
