Connect to ebusd over network

[stefanheijnen]

Description

I've got an RPi 4 with an Esera eBus Coupler USB. On the RPi (10.0.2.179) it's working as expected:

When I try to connect to it from my openHAB host, I get no signal.

ebusd -d 10.0.2.179:8888 --scanconfig -f -p 8888 --latency=10 --enablehex --latency=80 --acquiretimeout=20 --acquireretries=10 --receivetimeout=10 -c /home/openhab3/ebusd-configuration/latest/en

2022-11-21 20:15:59.615 [main notice] update check: OK, broadcast.csv: different version available, memory.csv: different version available

But ebusctl i gives:

update check: OK, broadcast.csv: different version available, memory.csv: different version available

Strange thing is, I can connect to it from within the the openHAB ebus addon:

It detects all my Vailliant devices:

Only issue is that the items get no data:

Actual behavior

It seems connected to the ebusd but it doesn't get a signal / data.

Expected behavior

I expect that ebusctl can connect to ebus over the network and gets a signal / detects my ebus components.

ebusd version

22.4

no idea about openhab, but the address+port you connect to seem to be wrong: when ebusd listens on port 8888 for ebusctl connection (or other TCP), then it can't connect to a hardware at the same IP and port (10.0.2.179:8888)
