Nezapomeňte na začátku kódu nastavit své správné proměnné (SSID vlastní wifi, heslo k wifi síti, správnou adresu serveru a GUID vyplněné v administraci na tmep.cz).

tmep.ino
// Simple sketch for sending data to the TMEP.cz
// by mikrom (http://www.mikrom.cz)
// http://wiki.tmep.cz/doku.php?id=zarizeni:esp8266
// If you send only temperature url will be: http://ahoj.tmep.cz/?mojemereni=25.6 (domain is "ahoj" and guid is "mojemereni"
// If you send also humidity url will be: http://ahoj.tmep.cz/?mojemereni=25.6&humV=60
// Another nice example with bulding HTTP GET request is here: https://github.com/SensorsIot/ESP8266-Longterm-Sensor-Hourly/blob/master/Sparkfun.ino
 
// Include WiFi stuff

  // Wait for DELAY, default 1 minute
  delay(DELAY);
