Does anybody here use the Popp keypad?

Configuration Z-Wave
1

I have the thing included, and it sends scene changes to Z-Wave, depending on which key I’m using. But I can’t for the life of me find out how to do an aoutomation triggered by that scene change. Does anybody have any code they can share? This is what I’ve tried, and it doesn’t work:

- alias: Popp-koder
  action:
    data:
      payload: scene_id
      topic: eg/Popp
    service: mqtt.publish
  condition: []
  id: '110223457'
  trigger:
    platform: event
    event_type: zwave.scene_activated
    event_data:
      entity_id: zwave.popp
      scene_id: 1
