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.
