For most of these events an internet connection isn't necessary at all.
My machine shows the time that is needed for the program when I start it. I know when it will be finished right from the beginning. There's no surprise, no message necessary. If I tend to forget the time, then I can set a reminder in my smartphone.
I can program the machine while I load it to start the washing later. Why load the machine but then program it from a distance? Makes no sense.
Detergent is filled in before each washing cycle. There's nothing to be depleted.
A maintenance or problem alert would be the only thing that could be worth a message function. But: My machine works without problems for 15 years now. So: what should it be messaging me? We can really live better without these useless electronics that only push up the price and the distraction.
