That said, if the washing machines that are in my building could send an email or SMS when they've finished or when they're hung up, that would be nice.
Of course, there would be some complexity: they'd have to know the email of the current user, they'd have to have some network connectivity (the building wifi doesn't reach them underground), etc.
