Dishwasher automation with condition


Trying to make our not very smart dishwasher to tell me when it is finished. I know, there are plenty of automations out there that does that but I can’t find one that fits my needs.
Actually it’s not that complicated. I’m using a smart plug that measures the power and when the washer is done, it turns off and drops to 0 watts, so the automation is quite simple to send a message at 0 W. What I’m struggling with is that I want it to do this only if it has reached over a threshold of X watts for Y minutes. The reason is that my kids often turns the power on (why can’t the power button be locked?) and we have to power it off and I don’t want that to trigger a message.
So what i need is a condition that says that the power must first have reached over a certain level before the message is sent when it drops to 0.

Thanks in advance!

I did this work well

then I add this

- id: f933e5a0-352c-4146-80d6-64ca01bae140
  alias: Dishwasher_door_open
  initial_state: true
    - platform: state
      entity_id: binary_sensor.dishwasher_door
      to: 'off'
    condition: and
      - condition: state
        entity_id: sensor.dishwasher_status
        state: 'Clean'
    - service: notify.alexa_media
          type: announce
          - media_player.lounge
        message: 'Thanks for doing that job.'
    - service: input_select.select_option
        entity_id: input_select.dishwasher_status
        option: Dirty

Thus is a great solution, it works well, but it might need a little tweaking. If you run a cycle on the dishwasher while watching the power draw for each stage of the cycle you can plug the numbers into the automation.
