How to...

1. Install Arduino IDE https://www.arduino.cc/en/Guide/HomePage and libraries for ESP8266 https://github.com/esp8266/Arduino
2. Add libraries: OneWire, ESP8266, ETHRENET, DHT, PubSubClient. Instructions https://www.arduino.cc/en/Guide/Libraries
3. In case you using ESP8266, open WebServer_mqtt_ESP8266_full.ino sketch, else you using arduino and eth shield, open WebServer_mqtt_ds_devinfo.ino
4. Edit sketch with your own data: for arduino:
   • char mqtt_server[] = ""; // server mqtt address
   • char mqtt_user[] = ""; // user name for mqtt server
   • char mqtt_pass[] = ""; // user password for ESP8266:
   • the same like for adrduino
   • const char *ssid = ""; // your WiFi AP name
   • const char *pass = ""; // WiFi password
5. Upload current sketch
