Openhab receives knx information but it cannot send to KNX bus

Setup, Configuration and Use Beginners

  • Platform information:
    • Hardware: qnap TS-251+
    • Router: FritzBox 7490
    • KNX IP Interface 730 Weinzierl
    • openHAB version: 2.2

I used a raspberry before. It was working but crashing quiet often. openhab on qnap seems to be stable but knx is not working. openhab receives the status of all knx components but it cannot send commands. I used the Basic UI. Also the NTP time cannot be send to the knx bus. So I guess it is no UI problem. I reduced now the items but cannot find the problem. I have not found this problem at Google. Usually the problem is that the command is sent to often.
Telegram is sending temperature information when it was decreasing below a specific value or if somebody is ringing the doorbell I get push notifications.
Does anybody has an idea regarding this?

  • configurations:

    type=ROUTER
    localIp=192.168.178.43

  • log when using Basic UI Switch:

Hello Tobias,

I have the same Weinzierl interface. Try using “TUNNEL” instead of “ROUTER”.
Using it in router mode caused issues on my installation.

Maybe this helps,
Thomas

Weinzierl 730 is only an IP/knx interface, not an IP/knx router.

Exactly, that´s why it´s not working.

Thank you. Stupid mistake.
