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? Regards, Simon

Thank you both for your answers. With so many parameters to play with, it was not easy to understand what was wrong.. But I think I finally got a way do get my hardware working Here are my findings : I thought I got RFM73 version of NRF24-like radios. They look like like here and here. After checking and connecting all VCC and GND together, switch radios and arduinos... I got them suddenly working with Mysensors development librairies, then back to silence without apparent reason... Indeed like @mark_venn suggested, I went back to stable librairies and try so set a static ID. Worked well... until it went back to silence again ! Then, following @mfalkvidd advice, I realised that flashing the eeprom_clear sketch solved my all my problems ! My summary : Ensure that your 3.3V power supply is strong enough. Ensure that your arduino, radios and sensors are sharing the same GND and VCC. Use development librairies from github Flash eeprom_clear before flashing your mysensor sketches Then gatewaySerial and relayActuator should be able to communicate "out of box", mean you'll monitor some lines like this on the gateway serial : 0;255;3;0;9;read: 0-0-0 s=255,c=3,t=15,pt=0,l=2,sg=0: Thanks again for your help, now I can start to play

You should not typ "\n"! It means that you should press enter on your keyboard. On Linux I saw that I have to send "\r\n" instead of "\n". "\r\n" (Carriage return, Line feed) is the Windows return, "\n" only the Linux return.

@hek Thanks for the comments. Sounds good. I'll report back when I have some progress.
