@nickrout Thanks ;-).
But i have tried the installation with Home Assistant OS. Copied the backup from my Raspberry PI 3 to the Odroid N2+ and now it works perfect for me. Really faster then before and i am looking forward to use home assistant now more and more Just tried the free month with Cloud / Alexa.
It’s a little bit confusing at the beginning with HA because of the installation types, many different opinions …
Thanks a lot for all your help and information! I am seeing a little bit clearer now.
