There are plenty of Alexa-enabled devices on the market. Even dryers are now capable of connecting to this service. Take the Kenmore Smart Gas Dryer for instance. It connects to your smartphone, allowing you to start or stop it even when you are not around. You also get notifications with the cycle is complete.
You will need a gas supply line and 110V grounded outlet for this. The dryer helps reduce odor while drying your clothing items. You can create new wash cycles on your smartphone.
