DALI with serial out

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

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

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



[{"id":"9acbc05221705fcb","type":"inject","z":"4aa2ed2fd1b11362","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[1, 48, 49, 48, 48, 49, 48, 70, 70, 48, 48, 69, 70, 23]","payloadType":"bin","x":195,"y":540,"wires":[["a9b5b08ef19a4c0d"]]},{"id":"a9b5b08ef19a4c0d","type":"debug","z":"4aa2ed2fd1b11362","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":435,"y":540,"wires":[]}]

Thanks a lot. It works.

Hi out of interest what what device are you using for USB to DALI ?

Hi, this one:

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
