Hi,  
so I have a KNX System and Installed the KNXJS node in Node-Red. The connection work and all my devices are controlable. But my problem is after closing the ETS and waiting around 10 min it says "Connected" but I cannot write and read to and from the bus.

Anyone who can help?  
Thanks in Advance
