currentcost Arduino nuelectronics ethershield Pachube

Arduino code to parse CurrentCost XML data and upload to Pachube using Ethershield from Nuelectronics. Averages of power and temperature data from XML feed (approx 5 second intervals) are calculated between uploads. A 1 minute interval seems to works best, Pachube averages the uploads recieved to 15 minute resolution. Nuelectonics Ethershield shield for Arduino has sample code for running as a HTTP server or HTTP client. This uses a HTTP PUT with connection close to upload data to Pachube. See keyvariables for basic configuration details. See pachube for data feed of original implementation.
