I am very grateful to this website.

The only unresolved issue is that when the browser auto-updates, the temperature and humidity numbers appear as gibberish. However, manual updates display correctly.

Can anyone provide any suggestions?

I am a newbie but I noticed in the code there are these lines in setup() function.

server.on(“/temperature”, HTTP_GET, [](AsyncWebServerRequest *request){
request->send_P(200, “text/plain”, String(t).c_str());
});
server.on(“/humidity”, HTTP_GET, [](AsyncWebServerRequest *request){
request->send_P(200, “text/plain”, String(h).c_str());
});

Should these two “send_P” calls be replaced with “send”? I was under impression that send_P is for PROGMEM variables.

Do i need to replace it or leave it as it is? If change required, how do i get what to replace with. Thanks once again.
