Rehau Nea Smart integration

Hello everyone,
I finally got everything wired and installed.
Waveshare RS 485 according to instructions etc.
My Nea Smart 2.0 also lights up on Sysbus. Waveshare also lights up blue and flashes. But I can’t find any devices… :frowning:

My questions:
Wave share:
Destination IP = IP of Homeassistant (Raspberry)?
Port = 502 always?
Gateway = My Fritzbox IP?
DNS = required? If yes, which IP address? Doesn’t matter?

Addon settings:
Liseting IP = Which IP do I enter here exactly?
ports = 502 ?

According to the addon it works. I have the following messages in the log:
s6-rc: info: service s6rc-oneshot-runner: starting
s6-rc: info: service s6rc-oneshot-runner successfully started

The funny thing is that when Running on * Running on http://127.0.0.1:5000
Running on http://172.30.33.1:5000 no IP of it is neither at Waveshare nor in my network.

what am I doing wrong here?
Can someone help me please?

add on (screenshot seems to work??)
But where I can find now the devices? I cant find anything

Modus goes from Normal to Standby - Temperature reset!

The temperatures in Homeassistant and also at Rehau itself are regularly set back to 7 degrees. What could be the reason? I’m desperate. I set the temperature (whether via the thermostat or home assistant) to 20 degrees and after a certain time it is back to 7 degrees
