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?

I built a trip wire for the post box that I'm connecting. It's however based on a mercury tilt sensor so I'm really not sure whether I think it's a great idea putting it to use (at least not with a sturdy case...). However, I can share my code:
#define DIGITAL_INPUT_SENSOR 2 // The digital input you attached your motion sensor. (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
MyMessage msgTripped(CHILD_ID_TRIPPED, V_TRIPPED);
void setup()
{
gw.sendSketchInfo("Postal", "1.0");
gw.present(CHILD_ID_TRIPPED, S_MOTION);
pinMode(DIGITAL_INPUT_SENSOR, INPUT); // sets the motion sensor digital pin as input
}
void loop()
{
boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == LOW;
if(tripped) {
gw.send(msgTripped.set("1")); // Send tripped value to gw
}
gw.sleep(INTERRUPT,FALLING, SLEEP_TIME);
}

On the same way, i dont understand how and where are stored the values inside the gateway if not used on each reception, are they stored somewhere to be able to answer them when serial request arrive?
You could bypass this on some kind of events obviously !
Actually my perl gateway is acting as the server Vera is for the arduino gateway. So from there I can trigger external URL, store data in a sqlite3 database... and so on !
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.
