We just added a new “Demo” section where data measured by the Dog gateway running in our lab is published. The page (that can be forked on GitHub) exploits the Xively.js API to fetch measures posted by the gateway on Xively.
We are planning to further improve this on-line demo by providing access to a real installation via the Dog REST APIs thus enabling developers to test their own applications without having to install the gateway locally.
Actions on devices will be visible through video-streaming (we are still investigating which solution to adopt, any suggestion is welcomed).
