Fibaro Dimmer 2 + Telldus Znet

I need help to configure my setup with Fibaro Dimmer 2 and Telldus Znet. I try to configure so I can use “Switch 2” to turn off the lights in the house.
I have activated “Scene” for the Fibaro DImmer in Telldus Live but I don’t really sure how to configure in HA (if possible)?

I have started with following:

  • alias: ‘Turn off all lights’
    initial_state: ‘on’
    trigger:
    • platform: event
      event_type: zwave.scene_activated
      event_data:
      entity_id: light.device_21
      scene_id: 26
      action:
      service: homeassistant.turn_off
      entity_id:
      • group.kitchen
      • group.living_room
      • switch.hall
