IKEA Tradfri shortcut button as trigger

Hi,
I had reset my home assistant (corrupt ssd and no complete backup) and I´ve used this to reconfigure my setup. Now I´ve a separate raspi with a deconz docker container. I´ve to learn all my zigbee devices to this new deconz instance but thats fine :). One thing I´ve trouble with it are my IKEA tradfri shortcut buttons. I can´t use the device as a trigger so I´m using deconz_event as a trigger but I´m confused about the logging entry:

From where comes the entry ... fired event 'Short press'? And could I use this a a trigger instead of the deconz_event?

Anybody knows it and would help me please?

Bye,
Michael
