Installing the fluksometer alternative visualizations is fairly easy. In the following I will provide a step-by-step description to change the FLM's default landing page (the pages you get when opening the FLM's local IP address in a browser window) to provide a bunch of alternative display variants as described in the flmlocal's ReadMe file.
You have your fluksometer up and running with the newest firmware version (currently 2.5.0 respectively 3.7.8) and know its local IP address; in this example I will use 192.168.0.114. When accessing this address in a browser, you will get following display.
I assume you have installed git, this splendid version control system, on your computer; if not, do so by either visiting git-scm.com or using whatever package installer runs on your computer (e.g. with sudo apt-get git on any Debian Linux Distribution).
Open a terminal window and clone the corresponding repository, that is, get the required files onto your computer. Use the command line
git clone http://github.com/gebhardm/flmlocal
The corresponding repository is now copied onto your computer into the directory flmlocal, added to the directory you are currently in.
As an alternative, download the corresponding zip-file from http://github.com/gebhardm/flmlocal and unpack it to a folder you know.
By default the master branch contains the last stable version of the newest Fluksometer hardware; this in my case is an FLM03E. If you use another hardware version, you have to switch branches. Perform a checkout for the FLM02:
git checkout flm02
There is also a branch for the FLM03; this you may use as alternative to the master branch for the FLM03; most likely they are identical. They may differ if I choose to test some new features. Note that a checkout works only, when you entered the repository's directory, you just cloned; so perform "at least" a cd flmlocal.
As the repository contains also a ReadMe file and this installation description, you have to switch directories and enter the one from where to copy the "correct" files onto your fluksometer. This is done, as depicted above, by a cd flmlocal/www. The www/ directory corresponds to the webserver directory already existing on the fluksometer. Into this we will copy some more content and overwrite two existing files (index.html and www/scripts/app.js) to add the visualization functionality.
An ls shows the files in this directory, just out of curiosity.
Now we will copy the content of the /www folder onto the fluksometer. As this is a remote file transfer, we have to use scp for this purpose (windows users here have to use WinSCP).
scp -r * root@192.168.0.114:/www/
This reads "securely copy recursively (-r) all files from this directory (*) with user root to the destination directory /www/ on location 192.168.0.114".
Note that in my case the secure access was performed for the first time, thus an RSA key is exchanged. You are prompted for a password; the default is root.
That was basically it; you may close now the terminal window and check your result.
When accessing the fluksometer local address again in a browser window (e.g. by refreshing the page from "beginning"), you will recognize the changes.
Two new menus now provide access to the added functionality.
Using the drop down menus you now may select the visualization to your convenience.
Note that the chart needs also the TMPO query daemon installed; this I will leave to the experts ;-)
