🎮 ZHA, deCONZ, Zigbee2MQTT - Ikea 5-button Remote Universal blueprint - all actions + double click events - control lights, media players and more with Hooks

Thank you for reporting. Could you please try to change these lines in the blueprint and see if it works?

- platform: event
  event_type: '{{ event_type }}'
  event_data:
    device_id: !input 'remote'
- platform: event
  event_type: zha_event
  event_data:
    device_id: !input 'remote'

Maybe the issue is that the template is not rendered at all, with the result of the trigger being invalid.
