It only would be a big problem if household devices like washing machines are built in a way that makes a connection to the internet mandatory in order to function properly. Imagine you can’t do your laundry because of an internet outage.
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, making it a internet-of-things-device. I can’t think of any.
We have a washing machine that cannot be connected to the internet. After starting the program, we set up a timer on our smartphone, 15 minutes longer than the time the washing machine display is predicting. Works like a charm.
