Xively (formerly Cosm and before that Pachube (pronounced Patch bay)) is an on-line database service allowing developers to connect sensor-derived data (e.g. energy and environment data from objects, devices & buildings) to the Web and to build their own applications based on that data. It was created in 2007 by architect Usman Haque. Following the nuclear accidents in Japan in 2011, Xively was used by volunteers to interlink Geiger counters across the country to monitor the fallout. In July 2011, Xively announced that they had been acquired by LogMeIn.
Xively manages millions of datapoints per day from thousands of individuals, organisations & companies around the world. Data can be pushed from the sensor or device end, with the data feeds then made available in multiple formats at no charge.
The service allows people to embed real-time graphs & widgets in websites; analyse and process historical data pulled from any public Xively feed; send real-time alerts from any datastream to control scripts, devices & environments.
