Understanding IR codes for Samsung TV

Question

Can somebody help me to understand how could I use RAW IR data in an project using ESP8266-HTTP-IR-Blaster library ?

I've created a NodeMCU board with an IR sender and receiver according to https://github.com/mdhiggins/ESP8266-HTTP-IR-Blaster

Everything is working fine as long as I'm using the captured codes for ex.: http://NodeMCU-IP/msg?code=E0E040BF:SAMSUNG:32 This is the Code for the Power button (E0E040BF)

As I'm using it in a home automation system, it would very beneficial for me if I had a dedicated ON and OFF sequence, which I found here: http://www.remotecentral.com/cgi-bin/mboard/rc-discrete/thread.cgi?5780 , but unable to translate, modify, or send it via RAW data.

Using Node-red, tried many ways, also implemented a MQTT client to the original project, but did not accept these codes anyhow I try. Does not sends it.

Also tried as a JSON, didn't help.

[
    {
    "type":"raw",
    "data":"[0000, 006D, 0000, 0022, 00AC, 00AC, 0015, 0040, 0015, 0040, 0015, 0040, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0040, 0015, 0040, 0015, 0040, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0015, 0040, 0015, 0040, 0015, 0015, 0015, 0015, 0015, 0040, 0015, 0040, 0015, 0040, 0015, 0040, 0015, 0015, 0015, 0015, 0015, 0040, 0015, 0040, 0015, 0015, 0015, 0689]",
    "khz":38
    }
]

Any idea what could I try next?
