Xively update issue


I have done a little project with Electric Imp
for the BBQ and got issue to get Xively to update with the temperature
when indeed it works just fine in the IDE (logs of the temperature are refreshing correctly)
Could you please have a look and let me know if anything wrong there?

This is coming from the project on Github https://github.com/joel-wehr/Tutorial_Electric_Imp_MAX31855

Please let me know if anything obvious that i miss or something wrong with xively side of things.
