Sometimes you can't remember wether the dishes in the dishwasher are dirty or not. Tell Alexa, and she will remember for you!
Open up the skill with "open my dishwasher" to tell Alexa whether or not your dishes are dirty. Open it up a second time to know whether or not your dishes are dirty.
You can tell Alexa the state of your dishes anytime by saying "Alexa, tell my dishwasher my dishes are clean."
