Hi There,
I’ve seen this problem some times but could never analyze in depth. I got these problem just now because my internet provider is working with some problems.
What happened is: When my internet connection has problems (let’s say it is down) OpenHabs EventBus doesn’t Receive Events from KNX Binding. At the bottom you find a part of the openhab.log with some errors.
My only idea is, that there is a connection with the InfluxDB Persistence which won’t be available on internet errors.
When I restart openhab (which is the only way to get KNX back running) it will receive KNX Events for a few minutes until it stops working again. In times without Internet connection errors OpenHab is able to run for multiple months without any problem.
Is there anyone out there having an idea what happened here?
