Thx for reply at first. You are right that to quote measurements as the safest way to compare and to avoid problems. I have to excuse, but my English is not the best. (learned 50 years ago)
I think the setup on Windows-Machine differs a bit from my openhabian-hassle free version.
I came to openHAB and Linux and that stuff a year ago or bit more using a RPi 3b. On this machine I’m now on 2.5.0.M4.
I never had problems with transformations of Units, either with or without Quotation Marks or with transforming it, as I learned a lot in this time from you and others (Rich, Udo, Scott, Jürgen, Bruce,etc.).
But yesterday I got my new RPi 4b and I made a complete new install of OH with the latest distro (which includes the workaround of the java problem) based on OH 2.4 stable.
At the end of the install-procedure I got the information that’s something wrong with the language settings. (I think it was a perl-script within the initial startup-procedure, which told me that something’s wrong with the environment variables LANG and LANGUAGE).
I tried to solve it with “openhabian-config” and setting it manually with the options of topic “30” | System Settings but it doesn’t work, and I saw that on my new system my test-rule produced the same error as @dsspindler described it.
When comparing my Environment-Setings from my “old RPI3b-Machine” and the new one , I found the environtment-variables LANG and LANGUAGE where different and so I changed it from
to
LANGUAGE=de_DE.UTF-8
LANG=de_DE.UTF-8
using the following commands on the shell:
export LANGUAGE=de_DE.UTF-8
export LANG=de_DE.UTF-8
I hope this can help others, to look on those variables when a similar problem comes up.
Cheers,
Peter

and understand what you mean.
