Hello everyone, I just can’t get any further. 
I have a test Hassio Server, Docker on Centos7 where everything works fine.
Now I have on my HP Mini PC, which is set up exactly the same (Centos7, Hassio on Docker), the installations commands are identical (I’ve looked into it carefully.), problems with the HASP display, this does nothing to me.
When I call the trigger it creates nothing like on my test Hassio Server as described here in the First Time setup.
It also doesn’t create the right name but just “Dummy” in the States.
I don’t have any errors in the logs, I can’t explain why it doesn’t work. I’ve been tinkering with it for more than six days now.
Does anyone have an idea what it is? I’m happy about any input I can think of.
What I have already tried out:
- Snapshot imported from Test server > didn’t fix the problem
- Set up a plain Server (Centos) > did not fix the problem
- Set up a plain Server (Ubuntu) > did not fix the problem
- Mosquitto broker addon, or just “mqtt” in the config.yaml without the Mosquitto add on (as it works on the test server).
- Searches every known log file for hours.
and much more… 
let me know if you need any information.
Thank you very much
