Hello everybody,
since I could not get my HestiaPi to run as I intended to do (see https://community.hestiapi.com/t/hestapi-stuck-at-0-screen-no-15-of-first-boot-one-tutorial, I am willing to sell them.
I live in germany, so it would be the best option, if you are also from germany 
Let me know, if you are interested.
