=== If you are at ITWM HPC ===

If you work for the ITWM HPC department, you can use a machine specially prepared to allow Flukso updates. The machine is located at the corridor, close to the printer cpsG1a. Please, take the following steps.
  - Login as user "flukso", informing the mySmartGrid administrator's password.
  - Connect the device to the cables available on the desk, properly labeled as "Flukso Power" and "Flukso Network".
  - Wait until the device right-most blue led starts blinking.
  - Double click the shortcut named "Update Flukso" available at the Linux Desktop. A terminal window will open. Please, wait its execution to complete. Ignore any message requesting password.
  - When the terminal window is closed, disconnect the cables. The Flukso device is up-to-date now.
  - If you have more devices to be updated, simply repeat this procedure from step 2.
  - When you finish, please don't forget to logout.

=== Update your Flukso to the for mySmartGrid adjusted version ===

For this method you need a POSIX compliant shell, ssh and expect installed.

The sourcecode is available at Mathias' github page: [[http://github.com/gonium/msg-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. We're only interested in the openwrt part.

The update script is located at openwrt/package/luci/applications/mysmartgrid/luasrc/tools/flukso_update.sh in git.
To update your Flukso make sure that it has access to the internet. If you want the Flukso to use the internet connection of your computer, enable IP-forwarding and change the IP in the update script.:

<code>
IP="192.168.255.254" # The IP of your computer
</code>

Then set your password in openwrt/package/luci/applications/mysmartgrid/luasrc/tools/flukso_update.exp:

<code>
set pass "yourpassword"
</code>

Now run the script while your computer is connected to the Flukso.

=== Update your Flukso to run the development version ===

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.

=== Updating the Flukso ===

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:

<code>
xmlrpcaddress = 'http://dev2-logger.mysmartgrid.de/xmlrpc'
</code>

Open heartbeat.lua and change the xmlrpcaddress and server entry to:

<code>
server        = 'dev2-logger.mysmartgrid.de',
xmlrpcaddress = 'http://dev2-logger.mysmartgrid.de/xmlrpc',
</code>


After restarting the flukso daemon, you should have a "/tmp/sensor" directory:
<code>
root@flukso:/tmp/sensor# ls
21dbb8a1b3b27e51d9b8384d6daf6a20  acff964b2308069847f02222bb3a6fd1
</code>

The last 60 seconds of measurements are stored there in JSON format:
<code>

In order to export these values create a symlink for the webserver:

<code>
# ln -s /tmp/sensor /www
</code>

Then the sensor readings can be queried from another machine like this:

<code>
$ curl http://192.168.2.102/sensor/acff964b2308069847f02222bb3a6fd1
</code>
