| + | |||
| + | 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. | ||

| - | 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.

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 | ||
