  24       <div class="date">12th March 2022</div>
  25       <div class="body"><p>Recently I had a look at a
  26 <a href="https://www.hargassner.at/">Hargassner</a>
  27 <a href="https://www.hargassner.at/en/products/wood-chip-boiler.html">wood
  28 chip boiler</a>, and what kind of free software can be used to monitor
  29 and control it.  The boiler can be connected to some cloud service via
  30 what the producer call an Internet Gateway, which seem to be a
  31 computer connecting to the boiler and passing the information gathered
  32 to the cloud.  I discovered the boiler controller got an IP address on
  33 the local network and listen on TCP port 23 to provide status
  34 information as a text line of numbers.  It also provide a HTTP server
  35 listening on port 80, but I have not yet figured out what it can do
  36 beside return an error code.</p>
  37
  38 <p>If I am to believe various free software implementations talking to
  39 such boiler, the interpretation of the line of numbers differ between
  40 type of boiler and software version on the boiler.  By comparing the
  41 list of numbers on the front panel of the boiler with the numbers
  42 returned via TCP, I have been able to figure out several of the
  43 numbers, but there are a lot left to understand.  I've located several
  44 temperature measurements and hours running values, as well as oxygen
  45 measurements and counters.</p>
  46
  47 I decided to write a simple parser in Python for the values I figured
  48 out so far, and a simple MQTT injector publishing both the interpreted
  49 and the unknown values on a MQTT bus to make collecting and graphing
  50 simpler.  The end result is available from the
  51 <a href="https://gitlab.com/petterreinholdtsen/hargassner2mqtt">hargassner2mqtt
  52 project page</a> on gitlab.  I very much welcome patches extending the
  53 parser to understand more values, boiler types and software versions.
  54 I do not really expect very few free software developers got their
  55 hands on such unit to experiment, but it would be fun if others too find
  56 this project useful.</p>
