RWE Binding

Add-ons Bindings
,
1

I had OH2 working on a windows laptop with the RWE binding.
Now I’m trying to install it on a RaspberryPi and it seems like I’m not getting a connection.
I’m working with the repository version, snapshot release.

What’s I’ve done so far:

  • I didn’t install the 2.0 software on the RWE Smarthome.
  • I’ve added rwesmarthome.items to the items folder
  • I’ve added rwesmarthome.cfg to the services folder
  • I’ve added EXTRA_JAVA_OPTS="-Djdk.tls.client.protocols=TLSv1" to /etc/default/openhab2
  • I’ve read through this post openHab2 RWE Binding
  • sudo apt-get update and upgrade

Here’s a dump form the (I think) relevant part of the log-file.
Can anybody help me into the right direction?

The SSLHandshakeException usually means that the TLSv1 option is not set. Which java version do you use? Mine one an odroid is the following:

$ dpkg -l oracle-java8-installer

I’m not a Linux-expert…but I think I have the latest java8 installed.

pi@raspberrypi-1:~ $ dpkg -l oracle-java8-installer
dpkg-query: no packages found matching oracle-java8-installer

But when I try to intsall it states that I already have the newest version.

pi@raspberrypi-1:~ $ sudo apt-get install oracle-java8-jdk
Reading package lists... Done
Building dependency tree
Reading state information... Done
oracle-java8-jdk is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.

and checking java version gives:

java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode)

How can I verify that the TLSv1 setting is done correctly?
The file /etc/default/openhab2 has only one line:

EXTRA_JAVA_OPTS="-Djdk.tls.client.protocols=TLSv1"

To be sure, you might try to add it directly into the karaf start script. You can find it in /usr/share/openhab2/runtime/karaf/bin/karaf. At the end of the script you find this block:

$KARAF_EXEC "$JAVA" $JAVA_OPTS \
            -Djava.endorsed.dirs="${JAVA_ENDORSED_DIRS}" \
            -Djava.ext.dirs="${JAVA_EXT_DIRS}" \
            -Dkaraf.instances="${KARAF_HOME}/instances" \
            -Dkaraf.home="$KARAF_HOME" \
            -Dkaraf.base="$KARAF_BASE" \
            -Dkaraf.data="$KARAF_DATA" \
            -Dkaraf.etc="$KARAF_ETC" \
            -Dkaraf.restart.jvm.supported=true \
            -Djava.io.tmpdir="$KARAF_DATA/tmp" \
            -Djava.util.logging.config.file="$KARAF_BASE/etc/java.util.logging.properties" \
            $KARAF_OPTS $OPTS \
            -classpath "$CLASSPATH" \
            $MAIN "$@"

Just add it before $JAVA_OPTS like this:

$KARAF_EXEC "$JAVA" -Djdk.tls.client.protocols=TLSv1 $JAVA_OPTS \
            -Djava.endorsed.dirs="${JAVA_ENDORSED_DIRS}" \

Better comment it out of /etc/default/openhab2 before running openHAB.

Yes, that seems to do it.
Thx!

PS, for anybody else with the same problem.
I’ve changed the /etc/default/openhab back to:

EXTRA_JAVA_OPTS=""

I had this working perfectly until the last Karaf 4.1.3 upgrade changed the syntax of the karaf script. Any idea where I have to add this line now?

I tried to add it twice like:

 if [ "${ROOT_INSTANCE_RUNNING}" = "false" ] || [ "${CHECK_ROOT_INSTANCE_RUNNING}" = "false" ] ; then
            if [ "${VERSION}" -gt "80" ]; then
                ${KARAF_EXEC} "${JAVA}" **-Djdk.tls.client.protocols=TLSv1** ${JAVA_OPTS} \

but I got stuck. Openhab2 does not start anymore.

The asterisks shouldnt be there. Maybe you just added them here in the forum. Without them it should work. I have no old Installation left and cannot check it.

Yes, I only added them in the post to highlight where I did the changes - not in the script. At least, good to know that it should work this way. I’ll keep trying. Thanks.
