Homematic trigger BidCoS-RF

Hello everybody,

I want to trigger to homematic virtual switch “BidCoS-RF” in Hassio.
My code is shown below.

automation:
  - id: '1560169742623'
    alias: BidCos_Test
    trigger:
    - event_data:
        channel: '50'
        name: BidCoS-RF
        param: PRESS_SHORT
      event_type: homematic.keypress
      platform: event
    condition: []
    action:
    - data:
        message: 'BidCoS detected - ############'
      service: system_log.write

In the syslog output you can see that the signal is detected but why the trigger not work correctly?

2019-06-10 12:53:47 DEBUG (Thread-2) [homeassistant.components.homematic] Event PRESS_SHORT for HM-RCV-50 BidCoS-RF channel 50

Thx for your help.
