Thx for reply.
I don’t know if it’s undocumented, as I found information about it here and here and of course here.
As I’m trying to learn Python/Jython/jsr223 and trying to migrate my DSL-Rules to Python-Scripts, I looked here and there and found the above sources.
As said I’m running OH with NGRE/JSR223 on my testmachine, where also the original “owm-script” of Scott is running, which has a lot of such features, and which is the base for my learnings.
Maybe OH3 will understand the code???!!
