 +  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 
 +  But for humidity You will need DHT11 or DHT22 sensor and code will need some modifications, see the other sketch.

 +  Blinking with ESP internal LED according status: 
 +  LED constantly blinking = connecting to WiFi 
 +  LED on for 5 seconds = boot, setup, WiFi connect OK 
 +  LED blink 2x per second = temp error (wrong pin, bad sensor, read -127.00°C) 
 +  LED blink 3x per second = connect to host failed 
 +  LED blink 4x per second = client connection timeout 
 +  LED blink 1x per [sleep] = send data ok
