How to convert 55 bit RF packets or send it out via MQTT?

[letshin]

I have an ecowitt 53 weather station that works through RF. The data packet has 55 bits such as below:

Ecowitt Wireless Outdoor Thermometer WH53/WH0280/WH0281A.

55-bit one-row data packet format (inclusive ranges, 0-indexed):

|  0-6  | 7-bit header, ignored for checksum, always 1111111
|  7-14 | Model code, 0x53
| 15-22 | Sensor ID, randomly reinitialized on boot
| 23-24 | Always 00
| 25-26 | 2-bit sensor channel, selectable on back of sensor {00=1, 01=2, 10=3}
| 27-28 | Always 00
| 29-38 | 10-bit temperature in tenths of degrees C, starting from -40C. e.g. 0=-40C
| 39-46 | Trailer, always 1111 1111
| 47-54 | CRC-8 checksum poly 0x31 init 0x00 skipping first 7 bits

Enabling debug: raw I can get the raw code below and can also convert it on Excel.

Is it possible to:

1. Send all this data using the MQTT protocol so I can convert it elsewhere eg on Node-Red or Python. I tried the below

    on_rc_switch:
      - lambda: !lambda |-
          char code[60];
          sprintf(code, "%llu", x.code);
          id(Kincony_Hub).publish("kincony/rf", code); 
``` but this appears to only send converted codes and not the raw format.
2. Is it possible to do the conversion through a lambda line?

Thanks

  on_raw :
    then:

            bool isGap = std::abs(i) < 1580;
            bool level = (i >= 0);
            if (level && (isOne || isZero)) {
              if (ones == 7) {
                bytes[bits / 8] <<= 1;
