I store all data from my sensors, thermostats, windows etc. to Xively. To monitor this data the generated graphs on the Xively site were not sufficient for me so i decided to take a walk with the Rickshaw Javascript library to create my own. I have build a website in a way everybody can use it to keep an eye on his data.
Thanks! Looks great! Would be great if there was also an option to download datapoints... hint hint XD
It's easy to use the Xively API to download datapoints.
