Hi @mariuszjozala , Thank you for reporting back. Glad that it works now! In my eyes, the good documentation (and availability of LTS options) is one of the really big plus points of the NanoPi/FriendlyARM products. I did save a local copy of their wiki, just in case it ever disappeared, because these references are really helpful. Best regards pragtich

@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

I found this old thread and since I have a Vallox machine it's interesting. RS485 is new to me but MySensors isn't. Can I have a node like this described by Heinz parallel with the "mickey mouse"-display? Using the display's connector? Or is it one or the other? I'd feel better having both (manual display&buttons and connection to MySensors=>Domoticz, in my case).

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
