Already built mine last year. Running same equipment above at feed:
https://cosm.com/feeds/70075
Here is my Arduino code:
// acefaser's beer code
#include <OneWire.h>
#include <DallasTemperature.h>
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { YOUR BITE MAC };
byte ip[] = { YOUR IP };
char server[] = "api.cosm.com"; // name address for Cosm API
EthernetClient client;
char strURL[150]; //define strURL
int t1,t2,t3; // variables for temps
// Data wire is plugged into pin 3 on the Arduino
#define ONE_WIRE_BUS 3
// cosm acct info
#define APIKEY "enter your key here" // replace your Cosm api key here
#define FEEDID 70075 // replace your feed ID
#define USERAGENT "Temp" // user agent is the project name
// 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:
