Hi all,
I’m currently trying to extend my openhab2 installation with ebus to take control of my Vaillant heating unit. However I’m getting an error in openhab2 from the ebus binding:
[ERROR] [nal.connection.AbstractEBusConnector] - An IO exception has occured! Try to reconnect eBus connector …
java.net.SocketTimeoutException: Read timed out

My setup looks as follows:
- Raspberry Pi 3B with openhab2 with ebus1 binding
- Raspberry Pi 2B with ebusd daemon, listening on port 8888/tcp
As my Pi2B is placed close to my heating unit (doing other things with owfs), I have attached it to the eBus via an USB-interface from esera. Communication to the eBus is doing fine and I have full sync and access to the eBus from the Pi2B.
As a second step, I’m now trying to connect from from my central PI3B with openhab2 with the eBus1 binding to the eBusd daemon via TCP.
I have configured openhab2 with the ebus.cfg with hostname and port of the PI2B (no serialPort!).
With netstat I see that openhab2 is connected by an IP connection to the eBusd, however I repeatedly get the error message above.
tcp 0 0 192.168.xxx.xxx:8888 192.168.xxx.yyy:33212 VERBUNDEN 15380/ebusd
Any idea what I’m doing wrong?
Is the ebus1 bindings hostname & port parameter intended to connect to an eBusd daemon?
Thanks for your help in advance! Any advise is greatly appreciated.
Regards
Karsten
