Hi together,
I could need a little help with the following problem: I am using a Homematic USB Stick (HM-CFG-USB-2) and got hmland and homegear working. Everything seems great, the devices are paired with Homegear and all are found and usable in openHAB, which I like very much. That’s the good news. 
What I just don’t get is, why is the state in OpenHAB not updated? I mean, if I manually switch something on or off (physically, not in openHAB), this is not shown in OpenHAB. (Also not after waiting for a few minutes, when refreshing the page, re-opening the browser, …) It’ll only be updated after a complete restart of OpenHAB on the server.
I’ve checked the homegear logs: The switch event is correctly registered there and as I interpret it, homegear then connects to openHAB on Port 9126 and sends the corresponding message, which is replied with an answer (please see log below). Strange enough I don’t see anything corresponding in the openHAB logs, even if I set the level to debug. 
I can’t make head or tail of it. 
The same seems to be the case when using e. g. the network binding: If a device goes offline, this is not recognized. (But a haven’t investigated this one in detail yet, so this might be misleading…)
Can you give me any hint?
(Disclaimer: Please forgive me, if this is a n00b or answered-a-thousand-times-already question! I have really been searching a lot before posting here… 
)
Many thanks in advance!!
