An internet connected oven, toaster, and fridge are treading awfully close to Cory Doctorow's novella UNAUTHORIZED BREAD. It's where there are IoT connected appliances in rent-subsidized apartments and the vendor gets a kick back from food purchased at stores with deals with those manufacturers. Put unauthorized food in the fridge, it turns off. Try to toast bread you baked from scratch after you bypassed the DRM scanning of your oven, it won't work. And of course it's a 5 year prison sentence and $100000 fine for bypassing DRM.
I helped my 80yo neighbor navigate her new oven, printing out the manual which did NOT come with the oven. I highlighted the key press sequences for a variety of tasks like setting the clock, setting a delay time, setting the oven temperature, broiling, and turning on burners. I also had to explain the difference between broiling, baking, and convection features. She had no interest in the air fryer feature and made the sign of the cross when I asked if she wanted to pair the oven with her iPhone.
