Openhabe 2 Homematic / can't find things

[desiw (Desiree Heckmann)]

Hi,

I installed openhabian on a raspberry 3 and installed the binding for Homemtic. The bridge is online.
If I go to the inbox then nothing can be found. Philipps binding is no problem.

Can anybody help me please.

Kind regards

Désirée

[Windrad (Ingo)]

Even the bridge is not found?
It can be searched manually within the items (i think). Must be edited then (IP)
After that, the allready paired devices should appear.

[ThomDietrich]

Hey, did you use the search function? There are numerous threads helping connect the homematic binding.

Connecting Homematic CCU2 with openHAB2

Hey, I’m totally new in openHAB and sorry if this question has been asked before. Anyway here is my goal: I want to connect my CCU2 with openHAB and want to add actions to openHAB, so openHAB is the main control software and the CCU2 is more like an “antenna” that connects to my different Homatic devices. After I set this up I want to connect it with the Amazon Alexa service to control common things with voice like “Alexa, turn down my heating to 20 degrees”. So but for the first it’s just con…

You missed to mention the device you want to connect to, I guess you already own a CCU2!? The linked thread describes how to set up the bridge. Good luck!

[desiw (Desiree Heckmann)]

The bridge is online and can be found.

[desiw (Desiree Heckmann)]

I have a CCU2 and I know how to search for things. My actors can’t be found when I am using the inbox.
Last December it was working. Today I installed openhab 2 new.

[ThomDietrich]

Ah, “bridge is online”, I’ve overlooked that.
Hmm that’s not normal. Did you do the usual (reboot, reconnect)? Please check the openhab.log file for suspicious homematic related logging lines. For any further help I’ll mention @gerrieg and @MHerbst

[gerrieg (Gerhard Riegler)]

It seems that the CCU sends empty datapoint names, fixed with

Homematic: Fixed NPE if datapoint name is null

[ThomDietrich]

Is this new behavior with the recently released CCU firmware?

@desiw If the fix posted by @gerrieg will solve your problem, you’ll need to wait a few hours till it’s merged and then use the latest snapshot version of the binding. @gerrieg I seem to remember you’ve described how to do so just recently?

[desiw (Desiree Heckmann)]

I installed the latest firmware on the ccu2. In Paperui I just installed the homematic binding. after I configured the binding and made a search in the inbox.

[gerrieg (Gerhard Riegler)]

Maybe it has something todo with 2.27.7, but i use this firmware too and everything works. Would be interesting to have a startup trace to see what the CCU sends.

@desiw
If it does not work with the snapshot after the PR has been merged, please post a full startup trace log, see Docs

You can update via apt with the Snapshot Release Repository or you can download the snapshot from CloudBees

[MHerbst (Martin Herbst)]

@ThomDietrich Maybe it is not necessary until it is merged, the new automatic PR build already created a jar file: https://openhab.jfrog.io/openhab/libs-pullrequest-local/org/openhab/binding/org.openhab.binding.homematic/2.1.0-SNAPSHOT/

[desiw (Desiree Heckmann)]

I installed the latest snapshot of the binding (2.1), but unfortunately no things could be found.

[gerrieg (Gerhard Riegler)]

The old jar file is still loaded, it’s impossible to have a NullPointerException in the new snapshot in line 26

[desiw (Desiree Heckmann)]

ok, I will install the 2.1 jar again. I installed Openhab 2 this morning new.

[desiw (Desiree Heckmann)]

Now it worked. All devices were discovered. thank you very much for your quick support.

Hi @gerrieg, @MHerbst,

I am just using the homematic binding and run a piVCCU on a raspberry pi 3.
I found the gateway by discovery and after adding it, the homematic bridge is shown in INITIALIZING.
Not sure where the problem is, maybe you can please help?

Thx

Thing 'homematic:bridge:FKE5056963' has been added.
'homematic:bridge:FKE5056963' changed from UNINITIALIZED to INITIALIZING

Hi @MARZIMA

for a test, I have installed the latest 2.4 snapshot on my Windows machine and this problem does not occur. The missing class is part of the Java SDK and contained in rt.jar (Java 8). Maybe your Java installation resp. an SD card is damaged.

Martin

[MARZIMA (Mehmet Arziman)]

Many Thanks @MHerbst! I will try to re test it

[NoTechi (Frederik)]

I might have done something stupid
After I moved from windows to a docker everything was working fine. I was discovering and creating homematic things with paperui and created items in a text file. After some time I noticed I might have old discovered homematic things in paper ui and I wanted to clean it. So I deleted all homematic things in paperui to make a fresh discovery. After a reboot and even a reinstall of openhab and the homematic binding I am not able to discover homematic things anymore. I can add the bridge manually and it shows as online. But even after that doing a discovery no things show up. Any hint is really appretiated

NoTechi

Update: Also deleting cache and temp folders did not help

Update 2: Found it. I had to set the firewall within hometic to allow access. Kind strange since this was working fine before but however it is working again!
