Energy logger data extraction

Introduction

elogger will read binary files recorded by VOLTCRAFT ENERGY LOGGER
3500 or 4000 and outputs the physical data in ASCII text format for
easy plotting or postprocessing. The current implementation is limited
to the binary DATA file type of the Energy Logger.

This project is targeted to GNU/Linux or other Unix users who do not
want to use the proprietary Windows-based data visualization program
as offered by the vendor but prefer free (libre) software where
possible. In case of the Energy Logger 4000, it is possible!

Specification

The underlying specification can be found at
Conrad. Here
you will also find the details about the DATA and INFORMATION
file types which the Energy Logger provides.

Usage

If you are an end user

Go to the Releases
page and download the latest tarball release (file ending
.tar.gz). You need to extract the tarball, build and install the
program. To do so, run these commands in the directory where you
downloaded or saved the release (replace <major>, <minor> and
<revision> with the corresponding version numbers of the downloaded
release):

tar xzf elogger-<major>.<minor>.<revision>.tar.gz
cd elogger-<major>.<minor>.<revision>
./configure
make
sudo make install

make install requires root privileges if you wish to install it
under the default installation path /usr/local. See ./configure --help for alternative configurations.

Program invocation goes by simply calling:

elogger <binfile>

in the directory where the binary files transfered from the Energy
Logger are stored. The output will be given on stdout. You can
save it to a file using shell redirection:

elogger <binfile> > output.txt

If you are a developer or maintainer

This project uses the GNU Autotools build system. Make sure you have
autoconf >= 2.69 and automake >= 1.16.1 installed on your
development system.

Either clone this repository with

git clone git@github.com:smartmic/elogger.git

or download the source code from the release page. Change into the
repository and run

autoreconf -i

to install the required scripts, then build the project as usual with

./configure
make

Contributions are highly welcome!

Status

This is a very early version and needs some more functionality and
documentation. Testing was done with an Energy Logger 4000.

Alternatives

There are a number of other open-source project out which will
basically do the same. Check them out if they suit your needs better.
