I’m trying to get the vitotronic binding with optolink on different raspi working. I use an original link cabel from vissmann and got vcontrold workin with it on /dev/ttyUSB0. But in order to work with OH2, I want to switch to the optolink solution. I´ve tryed to get it work like discribed here https://github.com/steand/optolink/wiki/Build-Install-Run . But when starting optolink there is an errror like this:
Native lib Version = RXTX-2.2pre2
Java lib Version = RXTX-2.1-7
WARNING: RXTX Version mismatch
Jar version = RXTX-2.1-7
native lib Version = RXTX-2.2pre2
17:51:58.761 [main] ERROR de.myandres.optolink.Main main - Something is wrong not init
I don’t know, how to solv this. I have no experiences in programming. When I try to install (apt-get install librxtx-java) there is the message: it’s already rhe newest version. I guess, there is the java version to upgrade, but don’t know how.
Please help!
I’ve solved the problem with different RXTX-libary versions by copy the same version into the java-path. But this leads not to the solution. It still seems, openlink could not connect to /dev/ttyUSB0:
gnu.io.NoSuchPortException: null
at gnu.io.CommPortIdentifier.getPortIdentifier(CommPortIdentifier.java:218) ~[optolink-jar-with-dependencies.jar:na]
at de.myandres.optolink.OptolinkInterface.<init>(OptolinkInterface.java:44) ~[optolink-jar-with-dependencies.jar:na]

Exception in thread "main" java.lang.NullPointerException
at de.myandres.optolink.Main.main(Main.java:46)
This leads me a step forward. Now the comunication between optolink and OH2 seems to work. When searching for new things in vitotronic-binding there will be found the bridge. But when I will activate it, i’ll get an error message like: Error 500 - Request failed. Any idea?
