Hello Archibald,

sadly your solution didn´t work but I found one elsewhere. I really appreciate your help and of course of the others that tried to help too. I enjoy this forum and it´s friendly users very much!!!!! :D :D :D :D :D
Here´s the final code for all people that may be interested ...

Hello Archibald,

Yes - you´re right. One has to use "server.send"!! With server.send_P I got errormessages. Using "server.send" and omitting "PROGMEM[]" did the trick. I don´t have to save memory so I shouldn´t have used it to begin with.
There´s one last question:
If you look at the code you ...

Finally it works - I had to get rid of the PROGMEM[] stuff - here´s the code and thanks a 1000 times for your help!!!!!

Dear Archibald,
Were you seeing "This should show the temperature" in your computer's browser before you made the last edit ?

Yes - because I was the one who made that statement - it was meant to be an example but all it did was making a mess :( Sorry!!
This time it compiles - but I can´t see a ...

First of all thanks to everybody for your answers!!
@Archibald
I tried your solution but I get an errormessage "assignment of read-only variable 'index_html'" Here´s the code so far!!!

Hello everybody,
I ´ve built a simple WIFi - thermometer with an esp8266 and a DS18B20 sensor. The software produces a simple webpage that can be viewed with a computer, cell phone and so on. I like that much better than using just the "server.send(200, "text/plain"" command but there´s one catch ...

Mystery is solved - this is what the display "really" shows - I reduced the text-size of "temperature" and found out!!
"tft.print(temperature,1);" does the trick - case closed! Thanks and good bye!!!

UPDATE!!!!!

When I declare "int temperature" instead of "float temperature" the phenomenon does not appear - see picture!!!

Thanks again for all you did for me - and of course I´ve changed "hpa" to "hPa" :D :D :D
BTW: I do print the integer and float values to the display - the old "substring-code" is commented out!
//tft.print(weatherdata.substring(0,4));// air pressure

all the best!!!!!!!

Hello Archibald,

I implemented your code and it works - of course. My webserver now sends "1017,23.8,28".
But there is one strange phenomenon :o Display.JPG
The value "humidity" has a strange "frame" now that wasn´t there before.
BTW: Excuse me for all those questions and misunderstandings - I´m ...
