eBus Integration - Fehler

[Markus]

Meine Wärmepumpe hat eine eBus Schnittstelle, mit Hilfe eines eBus-Ethernet Kopplers [1] sollten Daten ausgelesen werden können. Home Assistant bietet auch eine eBus Integration an [2], leider bekomme ich aber folgenden Fehler:

Logger: homeassistant.setup
Source: components/ebusd/init.py:70
First occurred: 11:33:26 (1 occurrences)
Last logged: 11:33:26

Error during setup of component ebusd
Traceback (most recent call last):
File "/usr/local/lib/python3.10/site-packages/ebusdpy/ebusdpy.py", line 14, in init
sock.connect(address)
ConnectionRefusedError: [Errno 111] Connection refused

During handling of the above exception, another exception occurred:

Der Koppler ist via ping erreichbar.
