How to read a variable from a custom_component (wiegand)

Hi all!
I got stucked with my first custom integration.
I want to integrate a rfid reader.

I have use the code from gdoerr
The code has been successfully read with my rfid reader and printed in the ESPhome logger

Now I have two choices.
1. I can publish the code to my “controlAccess” topic which has a script to check the access permission of the code. But my problem is I need 3 variables to complete the logic proccess:
payload= {
‘id’: ‘door’,
‘code’: wiegand_code,
‘timeStamp’: now()
}
and I dont know if would be possible to build in my esphome.yalm this structure and publish the json directly from the device in to the topic.

2. I could call a script which process the code and build the complete payload.
My problem is that the the script is not tiggered with this config and I dont know why.
My ESPhome yaml is:

custom_component:
  - lambda: |-
       auto wiegand = new WiegandReader(21, 23, "python_scripts.door_mqtt_publish.py");
       return {wiegand};

in config/python_scripts/door_publish_mqtt.py I have a simple code just to test it

logger.info("PYTHON SCRIPT CALLED")
name = data.get('code')
logger.info("HELLOOOOOOOOO %s", name)
hass.bus.fire(name, {"test": "from a Python script!"}
)

and I think that services is not mandatory, anaway:
config/python_scripts/services.yaml

door_mqtt_publish:
  description: publish a rfid code
  field:
    code:
      description: code format
      example: 9451293

In the ESP home logger I can see that the code is read perfectly but I can not trigger the python script to send the payload with the code on it. After read a code nothing appears in the HA logger.
