  32         <p>Recently I had a look at a
  33 <a href="https://www.hargassner.at/">Hargassner</a>
  34 <a href="https://www.hargassner.at/en/products/wood-chip-boiler.html">wood
  35 chip boiler</a>, and what kind of free software can be used to monitor
  36 and control it.  The boiler can be connected to some cloud service via
  37 what the producer call an Internet Gateway, which seem to be a
  38 computer connecting to the boiler and passing the information gathered
  39 to the cloud.  I discovered the boiler controller got an IP address on
  40 the local network and listen on TCP port 23 to provide status
  41 information as a text line of numbers.  It also provide a HTTP server
  42 listening on port 80, but I have not yet figured out what it can do
  43 beside return an error code.</p>
  44
  45 <p>If I am to believe various free software implementations talking to
  46 such boiler, the interpretation of the line of numbers differ between
  47 type of boiler and software version on the boiler.  By comparing the
  48 list of numbers on the front panel of the boiler with the numbers
  49 returned via TCP, I have been able to figure out several of the
  50 numbers, but there are a lot left to understand.  I've located several
  51 temperature measurements and hours running values, as well as oxygen
  52 measurements and counters.</p>
  53
  54 I decided to write a simple parser in Python for the values I figured
  55 out so far, and a simple MQTT injector publishing both the interpreted
  56 and the unknown values on a MQTT bus to make collecting and graphing
  57 simpler.  The end result is available from the
  58 <a href="https://gitlab.com/petterreinholdtsen/hargassner2mqtt">hargassner2mqtt
  59 project page</a> on gitlab.  I very much welcome patches extending the
  60 parser to understand more values, boiler types and software versions.
  61 I do not really expect very few free software developers got their
  62 hands on such unit to experiment, but it would be fun if others too find
  63 this project useful.</p>

  88         <p>After many months of hard work by the good people involved in
  89 <a href="https://en.wikipedia.org/wiki/LinuxCNC">LinuxCNC</a>, the
  90 system was accepted Sunday
  91 <a href="https://tracker.debian.org/pkg/linuxcnc">into Debian</a>.
  92 Once it was available from Debian, I was surprised to discover from
  93 <a href="https://qa.debian.org/popcon.php?package=linuxcnc">its
  94 popularity-contest numbers</a> that people have been reporting its use
  95 since 2012.  <a href="http://linuxcnc.org/">Its project site</a> might
  96 be a good place to check out, but sadly is not working when visiting
  97 via Tor.</p>
  98
  99 <p>But what is LinuxCNC, you are probably wondering?  Perhaps a
 100 Wikipedia quote is in place?</p>
 101
 102 <blockquote>
 103 "LinuxCNC is a software system for numerical control of
 104 machines such as milling machines, lathes, plasma cutters, routers,
 105 cutting machines, robots and hexapods. It can control up to 9 axes or
 106 joints of a CNC machine using G-code (RS-274NGC) as input. It has
 107 several GUIs suited to specific kinds of usage (touch screen,
 108 interactive development)."
 109 </blockquote>
 110
 111 <p>It can even control 3D printers.  And even though the Wikipedia
 112 page indicate that it can only work with hard real time kernel
 113 features, it can also work with the user space soft real time features
 114 provided by the Debian kernel.
 115 <a href="https://github.com/linuxcnc/linuxcnc">The source code</a> is
 116 available from Github.  The last few months I've been involved in the
 117 translation setup for the program and documentation.  Translators are
 118 most welcome to
 119 <a href="https://hosted.weblate.org/engage/linuxcnc/">join the
 120 effort</a> using Weblate.</p>
