Name any household device (washing machine, dishwasher, dryer, toaster, water kettle, iron, coffee maker, (microwave) oven, …) that has been improved in functionality by connecting it to the internet

I once heard of a toaster that could download patterns (character faces and so forth) then burn them onto your toast. Totally novelty but kinda cool if you could have Batman toast with breakfast. I don’t know if it actually exists as a product or was just a proof of concept though.
