• is a part of the volkszaehler.org smart meter
• is a tool to read and log measurements of a wide variety of smart meters and sensors to the volkszaehler.org middleware
• can run as a daemon or via cron
• includes a tiny onboard http daemon to serve realtime readings
• is written in C++ and should run on most embedded devices which conform to the POSIX standard

Feel free to implement support your own hardware ;)

To install, follow the detailed installation instructions at http://wiki.volkszaehler.org/software/controller/vzlogger/installation_cpp-version

If you're impatient you can quickstart using (Debian Wheezy):

sudo apt-get install build-essential git-core cmake pkg-config subversion libcurl3-dev \
  libgnutls-dev libsasl2-dev uuid-dev uuid-runtime libtool dh-autoreconf libunistring-dev

For Debian Jessie, be sure to add:

sudo apt-get install libgcrypt20-dev

For Debian Stretch, use:

sudo apt-get install git cmake autoconf libtool uuid-dev libcurl4-openssl-dev libssl-dev \
  libgnutls28-dev libgcrypt20-dev libmicrohttpd-dev libsasl2-dev libunistring-dev

For Debian Buster, use:

sudo apt-get install git cmake autoconf libtool uuid-dev libcurl4-openssl-dev libssl-dev \
  libgnutls28-dev libgcrypt20-dev libmicrohttpd-dev libsasl2-dev libunistring-dev build-essential

Ubuntu 18.04 LTS (bionic) needs an additional:

sudo apt-get install libunistring-dev

(this might be needed on others now as well as we link unconditionally against libunistring)

If you want to use MQTT support:

sudo apt-get install libmosquitto-dev

Then run the installation:

wget --no-check-certificate https://raw.github.com/volkszaehler/vzlogger/master/install.sh
sudo bash install.sh

You can also build a docker image:

 docker build -t vzlogger .

Note, that this will use the newest vzlogger from volkszaehler github (not your local clone). You can start it:

 docker run --restart=always -v /home/pi/projects/vzlogger-docker:/cfg \
 --device=/dev/serial/by-id/usb-FTDI_FT230X_Basic_UART_D30A9U5N-if00-port0 \
 --name vzlogger -d vzlogger

where /home/pi/projects/vzlogger-docker is the path to the directory containing the vzlogger.conf file and /dev/serial/by-id/usb-FTDI_FT230X_Basic_UART_D30A8U6N-if00-port0 is your device. You can pass several devices if you have them.
