I was going to try Xively based on one of the threads on the Aeon power monitor device. I ran into a snag, they’re no longer allowing free developer accounts.
I was digging around and found GroveStreams.com - has anyone else tried it? The API is straightforward, and their UI/data manipulation tools are pretty slick, and they have a free dev account. I asked, and they’re interested in getting more hobbyist developers experimenting with their systems.
There are per-minute call quotas and so forth, but been working fine for my purposes.
Has anyone else tried them?
