Genuinely curious, what benefit does having wifi in your microwave get you? You still have to put in and take out the food, and it's not like microwaves take all that long to cook food either. I also use maybe 2 buttons on my microwave (+30sec and cancel/stop), but maybe you can save particular power/time combos? Idk

I did like having a 'smart' washer/dryer in my previous apartment, as it would send me notifications about when the cycle was done and reminders if I let it sit for too long.
