Multiple Ds18b20 web server

I’ve found this code googling around and it works well, my only problem is getting it to extract the temperatures values and display them on a web page
I’ve tried to pass a variable in the client println page insideTemperature, but all I get are errors
I’ve already inputted the correct sensor addresses

#include <SPI.h>
#include <Ethernet.h>
#include <OneWire.h>
#include <DallasTemperature.h>
 
// Data wire is plugged into pin 6on the Arduino
#define ONE_WIRE_BUS 6

// Setup a oneWire instance to communicate with any OneWire devices
OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature. 
DallasTemperature sensors(&oneWire);

// Assign the addresses of your 1-Wire temp sensors.
// See the tutorial on how to obtain these addresses:
// http://www.hacktronics.com/Tutorials/arduino-1-wire-address-finder.html

DeviceAddress insideThermometer = { 0x28, 0xFF, 0x9E, 0x9B, 0x67, 0x18, 0x01, 0x33 };//=28 97 CA 29 5 0 0 63
DeviceAddress outsideThermometer = { 0x28, 0xFF, 0xAA, 0xBE, 0x23, 0x16, 0x03, 0x96 };//28 85 F6 3F 5 0 0 C2
//DeviceAddress dogHouseThermometer = { 0x28, 0x59, 0xBE, 0xDF, 0x02, 0x00, 0x00, 0x9F };
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
byte ip[] = { 10,0,0,102 }; // ip in lan
byte gateway[] = { 10,0,0,1 }; // internet access via router
byte subnet[] = { 255, 255, 255, 0 }; //subnet mask
EthernetServer server(80); //server port

}

but all I get are errors

And we've got to guess what they are?

No thanks.

Don't you just hate it when that happens?

Hi, Here's a different approach, using the free online Cayenne system. I have been using this to monitor and control temperatures in my log cabin in rural Vermont when I travel. And sometimes from upstairs when I want to heat the workshop while still making coffee...

Looks like this:

You apparently don’t bother to send the text you want to display to the web browser. I am not surprised that the text you don’t send is not displayed. You also forgot the closing tags for the BODY and HTML tags. I suspect that most browsers will assume you intended to send them.

          client.println("<BODY>");

            client.println("<H1>Arduino ATMega 2560</H1>");
            client.println("<hr />");
            client.println("
");

            client.println();
            //Envoi des données
            client.println("
"); 
            client.println("
");
            client.print("<b><h1><FONT COLOR=red>This is for test</FONT></h1>");
            client.print("<i>");
            client.println("
");

// SHOULDN'T THE STUFF TO DISPLAY ON THE HTML PAGE BE SENT TO THE CLIENT HERE?!?
// SHOULDN'T THERE BE A "</BODY></HTML>" AT THE END OF THE HTML?!?

            //stopping client
            client.stop();

Thank you for the suggestion, I had used blynk in the past but found it difficult and restrictive, while cayenne did the job perfecly.
I had to fiddle a bit as my board was not recognized, but I ended up fooling it as If I had an arduino, then swapped the ethernet libraries as wifi.
