I’ve just been playing around with Yahoo Pipes for the first time in ages to see if it might be useful in mangling data feeds from Pachube. (Would have been useful to have tried this out before homecamp but never mind!) Early signs looked good- falling off a log looks difficult in comparison to getting Pachube data into a Yahoo Pipe. Having said that, finding data feeds to start working with is not so easy. If I want to start doing something with power data, I have to manually find the relevant feeds on the Pachube site with a tag search. It would be great to be able to get a feed of data feeds; that would be useful for keeping up with new data feeds that get added to Pachube as well as being a useful input to a Yahoo Pipe.
So the simple example pipe for part 1 does just this kind of aggregation except that, because it’s a hack, it only includes a specified set of feeds. The default user input list is just the feed IDs I manually copied from that tag search for ‘power’:
It should work using my API key if you don’t have one, but you’ll need your own if you clone the feed to do something more interesting.
Coming up in part 2: doing something useful with the data.
