Wimp Weather Power Issue?

I am building a weather station using the wimp weather tutorial and I’m a little confused by how this is being powered. I didn’t see a good explanation in the tutorial but it looks like it is supplied power through the electric imp from the Sunny Buddy and wired to the 5V pin?

I am currently supplying power through the barrel jack on the Uno which works with a wall plug / 9 volt battery but doesn’t work with the power from the Sunny Buddy, when connected this way it appears to gather no info from the weather shield and reports no data to send then goes to sleep.

I am pretty new at this so any help would be greatly appreciated.

Figured it out

This may be a little bit late. But can you describe what the problem was?
