"Can't open CUL" on Synology Diskstation

goddib · September 2, 2018, 11:15pm

Hi everyone,

I have recently started the project of moving from fhem on a raspberry Pi to OpenHAB on my Synology Diskstation. Initial tests with an HTTP bind and switch worked fine so I moved on to integrate my intertechno compatible switches that I switch using a 433Mhz CUL stick.

Thanks to http://www.jadahl.com/ I was able to easily install the necessary drivers and after some trying I am now able to manually switch my switches from the command line. However, I have not been able to get openHAB to recognise my nanoCUL.

I read through what must have been dozens of threads and websites (mostly seeming outdated) and tried the following without any success so far:

chmod 666 /dev/ttyUSB0
add the following to openHAB/runtime/bin/setenv

EXTRA_JAVA_OPTS="
  -DlibNRJavaSerial.userlib=/volume1/@appstore/openHAB/userdata/tmp/libNRJavaSerial_openhab_0/libNRJavaSerial.so
  -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB0"

start openHAB from command line as root
add user openHAB to the http (and admin) group on the Diskstation

I can only guess that this is a permission or Java issue. However I’m not very experienced with Linux and as such am not sure what else to try. I have attached the openHAB.log below in case anyone around here has the patience to help me out. Any tips would be greatly appreciated.

Thanks in advance
Benjamin

If I remember correctly the group “dialout” was needed.

Hi Jürgen, thanks for your reply.

The Synology Diskstation doesn’t seem to have a group “dialout”. Of course I could set it up in the web gui - but in my understanding that wouldn’t do any good since it’s not integrated in the system permission structure.

How would I proceed after setting the group up and adding “openHAB” to the group? What other steps are necessary?

Thanks and regards
Benjamin

I’m sorry, but that question is beyond my Linux knowledge.
I always used a CUL on a raspberry using an openhabian image. Using that image solved all problems concerning the “Can’t open CUL error”.
