Hi there,
I have installed openHAB2 on a RPi3 the other day and I want to read data from my Novelan Heatpump.
I installed the Novelan/Luxtronic binding via PaperUI but it cannot connect to the heatpump due to a network error:
Ping is working, also from RPI3, Novelan firmware version is v 1.60, also the NovelanApp works.
Configuration should be fine?
# IP address of the Novelan (Siemens) Heatpump to connect to (required)
ip=192.168.7.4
# port number of the Novelan (Siemens) Heatpump to connect to (optional, defaults to 8888)
#port=
# refresh interval in milliseconds (optional, defaults to 60000)
#refresh=
In the log I find:

Let me know if you need more info, I am a newbee and no programmer.
I am also running successfully Grafana and influxDB on the RPi3 for a couple of months now, this should not be an issue? I have restarted the openhab2.service several times but the error keeps coming back.
Would be great if someone has an idea what I am doing wrong or how I can get more info about that error?
so here is what i have done so far.
I conencted via telnet to the heatpump and checked with netstat if there is something I can make sense of, i could not
After that I forced the heatpump control unit to reboot and I rebooted the RPi3, no change, still the same network error.
I asked Novelan support for help and they recommended me to update my heatpump firmware to the latest version (v1.8.1). So I did. In case you try to do the same, safe yourself some time and format your USB-Stick with FAT16 before…
So, now the network connect error in the log is gone, on top of that I can now also access the the heatpump via browser, that was not possible before
However there are intersting new line items to be found, that I can make no sense of:
2018-04-08 12:59:29.197 [INFO ] [lanheatpump.internal.HeatPumpBinding] - found new value for reverse engineering !!!! No idea what the heatpump will do in state 4.
2018-04-08 12:59:29.201 [INFO ] [lanheatpump.internal.HeatPumpBinding] - found new value for reverse engineering !!!! No idea what the heatpump will do in state 15.
Anybody an idea how I can stop these entries? They seem to be not critical, but they are written every minute and I am afraid they will eat up my diskspace…
Now I can continue my journey to transfer the heatpump data into my influxdb and visualize with Grafana
