My Button works fine, even with multiple triggers. I followed the adjustment as described here https://home-assistant.io/docs/z-wave/device-specific/
Afterwards, I could use the different triggers within the automation:
trigger:
platform: event
event_type: zwave.scene_activated
event_data:
entity_id: zwave.fibaro_button_black
scene_id: 1
scene_data: 7680 # 1-click 7680, 2-click 7860, 3-click 7920, 4-click 7980, 5-click 8040, long-click 7800, release-7400
I hope this helps
