One of our clients has made available his Python module to drive the Three-axis Hall Magnetometer THM1176. This code is provided as Open Source, with no support guarantees from either the author or Metrolab.
You can find the GIT repository here.
A heartfelt thanks to Cedric Hugon of Hyperfine Research for sharing. Of course, in the spirit of Open Source, we expect that any improvements you might make should also revert to the community!
