A new release is available for

openhab4 and openhab5

Add-on changes

  • Implement State data type mapping
  • Removed Item conversion, as the Add-on works now with “real” items on python side
  • Fix dependency watcher in case of using compiled pyc files
  • Fix ScriptEngine reinitialisation (in Transformation Services) after Add-on updates
    • Hopefully no “Context execution was cancelled” Exceptions after Add-on updates anymore
    • An Add-on update should work now without any exception (the old one can still raise an exception on shutdown) or openhab restart
  • Additional simplification of PythonScriptEngine & GraalPythonScriptEngine (~20% less code) => easier to understand for other people
  • Refactored VFS
  • Update helper lib to version 1.0.5

Helper lib 1.0.5 changes

  • Removed “Python => Java” type conversion for sendCommand and postUpdate. Is now handled inside the Add-on in a more generic way.
  • Replace error message TypeError: invalid instantiation of foreign object with a more helpful description like One of your function parameters does not match the required value type.
  • Initial integration tests started
