Need help with setting up some EnOcean devices

Allright then, my config looks like shown below now.
Now i am searching for the correct device IDs. Where exactly do i find them? I looked behind the switches and in the PCT14-Project the pre-owner of the house sent me. I tried different numbers but none of them look like the example in the HA EnOcean manual:

# Example configuration.yaml entry
binary_sensor:
  - platform: enocean
    id: [0x01,0x90,0x84,0x3C]

I tried different numbers i found but i always get this error:

Fri Jan 10 2020 18:37:40 GMT+0100 (Mitteleuropäische Normalzeit)

Invalid config for [binary_sensor.enocean]: expected int @ data['id'][0]. Got 'AB' expected int @ data['id'][1]. Got 'BA'. (See ?, line ?). Please check the docs at https://home-assistant.io/integrations/enocean/

Here is my config:


# Configure a default setup of Home Assistant (frontend, api, etc)
default_config:

# Uncomment this if you are using SSL/TLS, running in Docker container, etc.

#   base_url: example.duckdns.org:8123
