Hi guys,

I face the problem that openhab looses the connection to the KNX bus when I restart my internet + dns router. But only for specific items.

The openhab webinterface is accessible after the restart, also I can switch on/off lights via openhab homekit addon on my phone. But weirdly some messages are not processed correctly from the KNX bus.

I.e. my temperatures , lux measurement items all stay put. Here is what I mean:

Do you have any ideas? As said, beside that flat lines for all my temperature, light items, turning on/off/dimming is working fine :thinking:

Many thanks for taking your time!
