I am struggling in the following point: I use JS transformation with HTTP binding but looks like SCRIPT transformation is not supported in State Transformation and Command Transformation.

What specifically are you attempting to do and what is happening to make you think it is not supported?

Some things to consider:

• Syntax to use SCRIPT in the MQTT and HTTP binding is SCRIPT:<lang>:<filename>.script where <lang> is the language being used (graaljs for JS Scripting and I think js for Nashorn, dsl for Rules DSL), and <filename>.script is the file in the transform folder where the script stored.

• In OH 4 JS of either variety must be installed separately.

• Permissions on the .script file need to be such that the openhab user can read it.

• I may have uncovered a regression where OH needs to be restarted to see new .script files. See Executing the SCRIPT-transformation failed: Could not get script for UID '<filename>.script' (an issue has been filed).
