I think I found the problem. I think it misbehaved because of an illegal character in the "HOSTNAME". Changed the hostname yesterday and It was still alive this morning even if I have not pinged it.
Thanks for your fast reply.
That sounds easy.
And you think that the communication between sensor nodes and Gateway are still possible via wired RS485?
I tried to find an example on this site for sending Information from Gateway to sensor nodes. (via SendMessage ?)
For example I like to Switch on/off an light that is connected to an relay board at my sensor node.
Communcation Flow:
OpenHab2 --> MQTT --> Gateway --> RS485 --> Sensor Node --> Relay Board
Currently I have an working RS485 Connection between my Arduino Uno's with the use from SoftwareSerial library.
During my testings I realized, that the message that I triy to send "Hello" will be sent to the other arduino char by char. Is that true?
Because I tried to raise up an pin on HIGH with "if(msg == "Hello")..." But it doesn't worked.
Will the sendMsg method from the MySensor library handle this out of the box?

@suhaila96 Hello I have not seen your question since I reviewed this topics, today.
What do you mean about "setup your circuit"? How did you connected you watermark sensor and to what?
