Dear Helmut,

thanks for Your tipp.
And Yes the path is missing.

Could You please give me tipp how to phrase it correctly in the .py file?
I tried a few things, googled it, read a few things bu didn´t get it to work.
Here is  a screenshot of my latest (dump) try and a print of the $GRASS_ADDON_PATH

Best Regards
Stefan
