for some reason it does not seem to work. this is what i have in the automation

alias: Pornire Boiler
description: ‘’
trigger:

  • platform: zone
    entity_id: device_tracker.sm_g935f
    zone: zone.home
    event: enter
  • platform: zone
    entity_id: device_tracker.sm_g935f
    zone: zone.home
    event: leave
    condition: []
    action:
  • service: ‘switch.turn_{{ ‘‘on’’ if trigger.event == ‘‘enter’’ else ‘‘off’’ }}’
    entity_id: switch.boiler
    mode: single

is there something wrong with the sytax?
