pt cod din attach ai nevoie de fisierele astea:

#include <ESP8266WiFi.h>
#include <PubSubClient.h>
#include <DallasTemperature.h>
#include <ArduinoJson.h>

gasesti ultimele versiuni cautand pe google esp8266 si numele. apoi le descarci de pe github si le import in soft ul Arduino IDE inainte sa dai push la cod. pffff tu ai mai lucrat cu Arduino inainte deci stii.... eu nu stiam.
