This python module allows you to contact your Guntamatic BMK heater and get operational status information It includes an example binary 'heater.py' which can be installed as the guntamatic binary to instantly get data in your cli. The Guntamatic class can be used by IOT frameworks to be called regularly and plot data and the like.

The exact outputs might depend on your model and firmware.

release history

  • 1.0.1: don't generate an empty sensor as last line, skip empty lines
  • 1.0.2: update homepage
  • 1.0.3: clean up repo
  • 1.1.0: Add a parse_data function that does translations and skips diagnostic values. We now only return relevant values that have a hardcoded description.
  • 1.2.0: Raise an exception in parse_data if no Serial was present
  • 1.3.0: Always return all default sensors, even if they have None as value
  • 1.4.0: Translate to snake_case; Home Assistant prefers this, they are easier to split if you need to migrate.

  • 1.6.0: Add more sensors to get_data, rename domestic home water to domestic hot water
  • 1.7.0: Added support for devices in german, french, italian and spanish with mapping to fixed english output, removed supurflious print

roadmap

Currently this library only uses daqdata.cgi and dacdesc.cgi There is also a status.cgi json interface, and probably a lot more is possible when you have an api key (https://github.com/openhab/openhab-addons/tree/main/bundles/org.openhab.binding.guntamatic ) To be added in the future.

par.cgi returns a full list of internal parameters

?key=$KEY parameter should give you more options according to rumors You can get the key for your boiler from guntamatic tech Support.

ext/daqdesc.cgi?key= should give this in json format according to rummors. https://github.com/wolfgangr/guntaPERL
