Hello!

Firstly, sorry for such a big delay, I am really preoccupied last few months and haven't had an hour of free time. I've merged your commits, but haven't tested anything because I don't have NEC/Samsung remote. If some kind of problem comes up, I'll try to fix it, but I hope you'll be able to help me with NEC/Samsung part. Thank you for your contribution.

Best regards, Davor

Hi,

I have tested it and it works in my smarthome. so it must be OK )

[Xavier38330]

Can you give an example of NEC command and Samsung command ?

I failed to make it work, I always get the error "Command must be 4-byte hex number." or "Command must be 6-byte hex number.".

Thanks.

Hello!

Since I don't have NEC nor Samsung remote, @merlokk would be the right person to answer your question.

Best regards, Davor

It depends on device's model. It needs to grab it and then send command right for your device. as sample: my samsung

last 6 byte HEX data - data to send, before it - data in binary format

[merlokk]

there are too many byte's meaning. so you need to grab and reverse engineer code(

Sorry, I'm not sure I understand how to use it I have the following NEC sequence to send : 0xCFBB then 0x25. How should I write the BlackBean command ?

here encoding

D:\py\BlackBeanControl>samsung.py -n 4DB2FD023DC2

and this bin command needs to put into BlackBeanControl.ini

If you want - you just can implement sending command from parts of code in samsung.py and blackbeancontrol.py
