Wondering how to write this event, turn fan off if door has been open 20 mins

Configuration

Looking at maybe switching from HomeSeer but not clear how I’d do this event:

  • If guest bathroom door closes, turn the fan on
  • If the guest bathroom door opens and stays open for 20 minutes, turn the fan off
  • If the door closes again during those 20 minutes then cancel that and leave the fan on

You can do that pretty easily with AppDaemon. Just take a look at the tutorials. IIRC the first tutorial matches your situation quite well.

It’s 2 automation.
One to turn the fan on:

automation:
  - alias: Turn ON bathroom fan
    hide_entity: True
    initial_state: 'on'
    trigger:
      platform: state
      entity_id: device.door_sensor
      from: 'open'
      to: 'close'
    action:
      service: switch.turn_on
      entity_id:
        - switch.fan

And one to turn it off:

automation:
  - alias: Turn OFF bathroom fan
    hide_entity: True
    initial_state: 'on'
    trigger:
      platform: state
      entity_id: device.door_sensor
      from: 'close'
      to: 'open'
      for:
        minutes: 20
    action:
      service: switch.turn_off
      entity_id:
        - switch.fan

It will only turn off if the door has been opened 20 minutes ago and is still open.
