Hello,  
I am trying to set up DALI lights with UniPi PLC and NodeRed  
I have USB RS232 to DALI interface. It works flawlessly with python.  
I should send ASCI format of message on serial port.  
Example - switch off all message : 0x01 0x00 0x10 0xFF 0x00 0xef  
and asci representation as list (in python I am sending this list on serial port]  
[1, 48, 49, 48, 48, 49, 48, 70, 70, 48, 48, 69, 70, 23]

How I should do it with node red.  
Combination of inject and serial out did not work for me  
With thanks  
Karel

You should be able to send a buffer like that to serialport

Thanks for reply, how I should do it, please? 🙂  
I am quite new in node red (few hours)  
In inject I should set payload type to buffer?

Thanks that look's like a very useful device I mainly go KNX DALI but on occasions have been asked for something like this. Cheers
