How to discover the event ID using RFXcom and Kaku

Hi there.
I’m quit new to Home Assistant. Bought my self a RFXcom.
I’m running Home Assistant on a Raspbarry Pi.
I can’t figure out how to discover which button on my remote are triggering Home Assistant.
I have a Kaku remote with 4 separate keys and a group key, a doorbell and a Itho Daalderdorp (for the ventilation of the home).

In Home Assistant I use the integration RFCtrx which found 7 devices ans 21 entities (switch, sensor and a binary_sensor).

But If I go trough the log files I don’t see any reaction on the moments I aspected. Also don’t see the correct states.

How do I get the event ID?

After checking my RFXcom with the rfxmngr I’ve added some extra protocols.
Now I have 10 devices with 30 entities.
But still now sign of my pressed buttons in my log files.
My config.yaml looks like:

# RFXtrx

rfxtrx:
  device: /dev/ttyUSB0
  debug: true

switch:
  platform: rfxtrx
  automatic_add: true
  
binary_sensor:
  platform: rfxtrx
  automatic_add: true

logger:
  default: error
  logs:
     RFXtrx: debug
     homeassistant.components.rfxtrx: debug

Answer to my own question.
The main problem was the location of the RFXcom.
Since my doorbell is receiving at almost the same location I tought that the device would as well.

Moved it to an other place and it worked.
Also changed the config to:

# RFXtrx

rfxtrx:
  device: /dev/ttyUSB0
  debug: true

logger:
  default: error
  logs:
     RFXtrx: debug
