Hey

I´m using a small VIS to toogle some KNX and Zigbee lights (Zigbee light is also switchable via KNX switch).  
I´m using the nodes of this package: [https://flows.nodered.org/node/node-red-contrib-knx-easy](https://flows.nodered.org/node/node-red-contrib-knx-easy)

The first ~ 30 seconds everything works fine:

- Lights are witched
- Status changes on KNX switch
- I can see that the node writes groupadresses to KNX

But after a few seconds, it doesn´t work any more.  
The status of the node still shows "connected", but it doesn´t write any groupadress to the KNX (At least, I can´t see them in the Monitoring view of my ETS)

When I remove my KNX Ip Interface from the network and connect it again, it works again for 30 - 60 seconds.

Does anyone of you have an idea?  
Thanks a lot 🙂
