One small issue is that negative temperatures are shown as positive value.

Im currently having a temp of -4 deg C and the webserver shows 4 deg C.

Also: how can I modify to only have temp showing. I have done it on what you see but when I try to remove all with ths SSR's The web page won't load.

EDIT:

Could I just simply use signbit to add in a "-" ?

Kind of the same way as tou use the SSR bytes for on and off??

Your  problem is here
Code: [Select]
byte sensor1[8] = { 0x28, 0x61, 0x24, 0xC5, 0x03, 0x00, 0x00, 0x51};  // User Defined Temperature Sensor Address 1

Use the temperature example from the Onewire Library to find your DS18X20's address , then copy and replace the existing address with a new one.
