This is an old revision of the document!
The sourcecode of the Flukso is available at Bart's github page: http://github.com/icarus75/flukso. Clone it to have your own local copy. The repository contains the three parts: Microcontroller firmware, Router board software (openwrt) and the code for the website.
For the local interface to work you have to update the Lua scripts installed in ”/usr/share/lua/flukso”. I suggest that you make a backup copy. Then you simply scp the updated files from the github repository to the Flukso. If you're using mySmartGrid, you have to adjust the logging location afterwards. Open flukso.lua and edit the xmlrpcaddress entry to look like this:
xmlrpcaddress = 'http://dev2-logger.mysmartgrid.de/xmlrpc'
