Yes, that works!
You saved me a lot of time, thanks.
I am a beginner in HA and i just installed my miele integration but it does not recognize any devices and I don’t know where to begin to fix this issue 
Welcome @razclud
This is a good link to bookmark: The Home Assistant Cookbook - Index
It has a section on troubleshooting at the bottom.
If something doesn’t work, don’t get stuck on it for too long. Just move on and revisit the issue after a few weeks/months. This will help you learn in small increments.
