State changed event fires when state hasn't changed

I have the following automation:

jamesking420/home-assistant/blob/0dfe711e88fa49716b1a96ede84b385f0bf41487/nursery_state_changed.yaml

- initial_state: 'on'
  alias: Turn Off Nursery Booleans
  trigger:
    platform: event
    event_type: state_changed
    event_data:
      entity_id: light.nurserycolourhue
  action:
    - service: input_boolean.turn_off
      data:
        entity_id: input_boolean.nursery_blue, input_boolean.nursery_high_red, input_boolean.nursery_low_red, input_boolean.nursery_white

I was hoping this would only fire when i change the brightness, colour, etc of the lights., but in fact it seems to fire every 10 (or so) seconds, regardless of if I’ve made a change to the light. The only way I can understand this is that it happens because the state of the entity is republished by deconz, which I use for controlling my zigbee lights. Is there a better way to run an automation only when a light actually does change ? Or is there another suggestion of what I could do here?

Thank you,

James
