I am trying to read an environment variable (with a real value) into a Code-device. The value comes from a two-wire temperature
sensor already hanging on a (the) raspberry. I tried : parseFloat( os.system.getenv ( "var-name" ) ), but I get an error message:

Reference error , (os/system/getenv) ... not defined.

I know, I am not an experienced Java programmer (and I don't want to be one), but some examples of javascript code (for the Code-device) would be very welcome (in this forum or the Zway manual).

Integrating already present sensors and actuators in this z-wave world is, in my opinion, a must. There should be a Howto (integrate other sensors) somewhere.

Also the HTTP device is hardly documented. Some examples would be welcome.

Thanks for any help!!

Environment variables live in the context of bash. You can not use them to do your task.

Better push them via /JS/Run API in the JS engine or read them via system("some shell command") from JS code
