Yeah, my parents purchased a Miele.
M&D initially wanted to use the Miele app to control the washing machine.
I explained that having an IoT device connected to the same network on which they performed their internet banking was a *bad* idea. (Would Miele ever bother to patch flaws in the firmware?)
Plus, they'd be telling Miele where they lived, how often, and how, they used the machine as well as probably telling Miele their WiFi password.
I *think* that Miele's power and water consumption algorithms use the same mathematical formulae as Douglas Adams' 'bistromaths'.
