Device grayed out for new automation

I am trying to set up a custom automation to alert me when my washing machine has finished but when I try to create the automation the device option is grayed out so I cannot select it. I checked to be sure that the device is connected, and it is because I can see it when it is awake and washing laundry, but I don’t see how to make it available to add a notification. Maybe I have the washing machine set up wrong?
