2vz

Synopsis

Various tools to read and send data to a volkszaehler.org middleware

The tools

  • vzspool is used as a spooling relay by the other 2vz tools. Right now it's just a perl script, but I'l re-implement it in C (like the others)
  • d0vz reads D0 meters
  • ev2vzs uses Linux' input event subsystem to get S0 impules with a proper time resolution
  • thz2vzs reads operational data from (some) Stiebel Eltron and Tecalor heat pumps (THZ/LWZ 304 and 404)

Installation

  • create an unprivileged user "vz"

    # useradd -d /var/spool/vz -r vz

  • create the log and spool directories

    # mkdir -p /var/log/vz /var/spool/vz

    # chown vz: /var/log/vz /var/spool/vz

  • customize configuration

    # mkdir /etc/vz

    # cp vzspool/vzspool.conf /etc/vz

    # vi /etc/vz/vzspool.conf

  • build and install the tools you want

    # cp vzspool/vzspool /usr/local/bin

    # cd d0

    # make

    # (t.b.c.)

  • setup startup. I provided service files for systemd (I use Fedora and that's just how you do it there), but SysV init scripts should not be too hard to create, though.

    # cp vzspool/vzspool.service /etc/systemd/system/

  • start the services you want

    # systemctl start vzspool # systemctl start d0vz # ...

  • check logfile

    # less /var/log/vz/vz.log

  • (optional) set up logrote. The log may grow quite fast (esp. with S0 input), so daily rotation is reasonable

    # cp vz.logrotate /etc/logrotate.d/vz
