Let's dig into that direction then ...
Where can I configure the mysensors plugin to have or the look the IP adress of the jeedom system it is installed into ?
Shouldn't that be allready made directly in the source code of the mysensors plugin ?
Not sure that this is the reason of the bug ...
Anyone with other ideas ?

You're right, my bad, I paste bad logs in which I hadn't the sensor disconnected.
Now if I disconnect all of it (the gateway and the sensor), then I reconnect the gateway and the the sensor, I still have the issue (I confirm having the right presentation lines in the sketch).

Again, any ideas anyone ?

Hi

I used latest libraries and code examples.
I can see my temperature sensor sending information on it's serial port.
I can see my ethernet gateway getting these temperature information.
I can reach my ethernet gateway through it's IP adress with basic nc command line and I see my temerature messages arriving through this path
I installed the mysensors application on my jeedom controller and activated the debug option.
It seems it's getting some info, but it doesn't create a node or an object, i haven't got nor the gateway nor the temperature sensor.
Any ideas / advice ?

FYI, here are the logs on jeedom :
