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 (At time of this writing it is located under flukso/mote/v1/openwrt/package/flukso/src in git). 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'
After restarting the flukso daemon, you should have a ”/tmp/sensor” directory:
root@flukso:/tmp/sensor# ls 21dbb8a1b3b27e51d9b8384d6daf6a20 acff964b2308069847f02222bb3a6fd1
The last 60 seconds of measurements are stored there in JSON format:
root@flukso:/tmp/sensor# cat acff964b2308069847f02222bb3a6fd1 [[1279099535,0],[1279099536,0],[1279099537,0],[1279099538,0],[1279099539,0],[1279099540,0],[1279099541,0],[1279099542,0], [1279099543,0],[1279099544,0],[1279099545,0],[1279099546,0],[1279099547,0],[1279099548,0],[1279099549,0],[1279099550,0], [1279099551,0],[1279099552,0],[1279099553,0],[1279099554,0],[1279099555,0],[1279099556,0],[1279099557,0],[1279099558,0], [1279099559,0],[1279099560,0],[1279099561,0],[1279099562,0],[1279099563,0],[1279099564,0],[1279099565,0],[1279099566,0], [1279099567,0],[1279099568,0],[1279099569,0],[1279099570,0],[1279099571,0],[1279099572,0],[1279099573,0],[1279099574,0], [1279099575,0],[1279099576,0],[1279099577,0],[1279099578,0],[1279099579,0],[1279099580,0],[1279099581,0],[1279099582,0], [1279099583,0],[1279099584,0],[1279099585,0],[1279099586,0],[1279099587,0],[1279099588,0],[1279099589,0],[1279099590,0], [1279099591,0],[1279099592,0],[1279099593,0],[1279099594,0]]
In order to export these values create a symlink for the webserver:
# ln -s /tmp/sensor /www
Then the sensor readings can be queried from another machine like this:
$ curl http://192.168.2.102/sensor/acff964b2308069847f02222bb3a6fd1
If you work for the ITWM HPC department, you can use a machine specially prepared to allow Flukso updates. It is located at the corridor, close to the printer cpsG1a. Take the following steps.
1. Start the machine and choose the first Linux image. 2. At the login page, enter the mySmartGrid administrator's password for the user “flukso”. 3. Connect the Flukso device to the power cable and network cable available on the desk. They both are properly labeled as “Flukso Power” and “Flukso network”. 4. Watch the Flukso device blue leds, and wait until the right-most one starts blinking. 5. Double click the shortcut named “Update” available at the Linux Desktop. A terminal window will open. Please, wait its execution to complete. 6. When the terminal window is closed, disconnect the cables. The Flukso device is up-to-date.
