Hi PJR, now it is working with this code in the MyTransportRS485 without any changes on MySensors.h: #if defined(MY_RS485_SWSERIAL) SoftwareSerial& _dev = MY_RS485_SWSERIAL; #elif defined(__linux__) SerialPort _dev = SerialPort(MY_RS485_HWSERIAL); #elif defined(MY_RS485_HWSERIAL) HardwareSerial& _dev = MY_RS485_HWSERIAL; #else AltSoftSerial _dev; #endif As far as I can interpret the peace of code, the #include "hal/transport/MyTransportRS485.cpp" is active as soon as the MY_RS485 layer is defined. This is a great step, I can use all my nodes from now on! Thank you very much for your support! By Kduino

@kimot in theory you might be right, but in practice... it just works. The propability of collisions is extremely low and this is, as far as I know, the only problem you can worry about. After all, it was not my idea to use MySensors with RS485: https://www.mysensors.org/build/rs485

@YuryPol as far as I know, all licenses require some form of documentation. In all cases I know of, this is documented with the license or on the licenses official site.

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

Hello Berk, Is it possible for you to share your schematic for this project please? especially the power part?

This is great, thanks! One suggestion: add a switch mode regulator that can handle 12 or 24 volt DC input. This will allow small sensor devices to hang off a typical bus network having extra pairs for the central power supply.
