I am trying to receive the current state of a remote switch using OpenHAB. Currently, I can trigger the switch from OpenHAB (and the state is correctly set within OpenHAB). But if I use a Homematic Remote to trigger the switch the state of OpenHAB does not change.
This is my current setup:
The switch receives the trigger using a homematic direct connection:
The switch has the following item in OpenHAB: Switch ledsteckdose "LEDs Stahlträger" (gLighting) { homematic="address=LEQ1068281, channel=1, parameter=STATE" }
The web frontend shows the state of the switch: Group item=gLighting label="Beleuchtung" icon="firstfloor"
If I reload the datapoints manually, I receive the correct state from the CCU2. This is the item I use: Switch reload_datapoints "Reload Datapoints" (Admin) {homematic="action=RELOAD_DATAPOINTS"}
I therefore assume that my basic configuration is correct. Digging into the documentation I read about the “Variable/Datapoint sync”.
Back within OpenHAB the following two items should trigger a state sync: Switch VK_Reload_Variable (gHomeMatic) {homematic="address=BidCoS-RF, channel=1, parameter=PRESS_SHORT, action=RELOAD_VARIABLES"} Switch VK_Reload_Datapoint (gHomeMatic) {homematic="address=BidCoS-RF, channel=2, parameter=PRESS_SHORT, action=RELOAD_DATAPOINTS"}
BUT: I do not receive anything on the OpenHAB side of things. The events.log shows messages like 2015-09-10 10:48:01 - ledsteckdose received command OFF but nothing with respect to VK_Reload_Variable or VK_Reload_Datapoint.
For me it sounds like the connection between your openHAB binding and the CCU is just partially working. The binding is normally subscribing to the XMLRPC event interface of the CCU. Because of this you should automatically see every change of a Homematic device that has correct binding information.
In your case it seems to work just in one direction and you have to “pull” the changes via RELOAD_DATAPOINTS. But this is normally not the way it should be.
thanks for your analysis. I looked at my log files but did not find an entry related to XMLRPC. Is the “Homematic Communicator” or the “BinRpcClient” the right communication interface? O also found some lines from the “AbstractTypeConverter” that translate all my devices (including the virtual remote ones) correctly. The full startup log looks like this:

To track that issue down I would propose to disable / deactivate the virtual remote things in CCU2 and the triggered datapoint reloading in openHAB. As the docs say it is only needed if openHAB events shall be triggered by the change of an ccu2 system variable.
The first check would be to see if the state of “ledsteckdose” changes in openHAB when the HM-LC-Sw1-Pl-2 actor is triggered on the device itself. If this is not working there is a general communication problem between CCU2 and openHAB.
In my setup I have not the same actor like you but a similar device (wall mount light switch HM-LC-Sw1PBU-FM) and the behaviour is consistent even if the actor is triggered from the bound openHAB switch or from the device itself.
By the way - did you check your CCU firewall settings ? As far as I remember the access to the XMLRPC is partly restricted by default so be shure your openHAB node is within the allowed networks.
The CCU firewall must be configured to 'full access' for the Remote Homematic-Script API
Also interesting might be your openhab.cfg (the homematic relevant part at least).
I know that I have just the “homematic:host” set to the right IP Address and all other options are still default (by keeping the # in front of).
This set me on the right track: My CCU2 listens on 192.168.1.110, my RPi running OpenHAB on 192.168.1.111. I misconfigured the callback setting:
# Hostname / IP address for the callback server (optional, default is auto-discovery) # This is normally the IP / hostname of the local host (but not "localhost" or "127.0.0.1"). homematic:callback.host=192.168.1.110
Instead of .110 it should read .111 - now everything works as expected.
@rbausdorf: Thanks for your advice regarding using the device’s trigger to switch it - I didn’t think of it, but I will remember this for future debugging sessions.
