This is a combination of several questions and a few observations.

Miele offers their RemoteVision function on many -- not all -- models of their appliances.
They describe RemoteVision as a “monitoring service” available upon purchase and activation of the wireless (WiFi) module.

This is obviously the basis for IOT with Miele appliances, IOT is defined as:

A proposed development of the Internet in which everyday objects have network connectivity, allowing them to send and receive data. "If one thing can prevent the Internet of things from transforming the way we live and work, it will be a breakdown in security"

Remote Vision is discussed and mentioned very little on here. Yet it has a lot of potential.
One example I stumbled on, there’s a Miele SmartPhone app from which you can monitor and do limited control of your appliances. It looks very cool. Here’s a link to the Android version:

I’d presume there’s an apple version also.

Here’s a press release announcing the app: http://www.miele.de/en/m/miele-at-mobile-app-everything-under-control-2441.htm

Has anyone ever seen or used this app? Unfortunately I see the message “This app is incompatible with your device.”

This app and it's features are almost secret, I only found it by accident. You’d think Miele would play this up as a very cool feature.

Yet the opposite is happening, even in some product manuals there is no mention of RemoteVision. You have to go to a support section of the MieleUSA website, and once there you get a somewhat disconnected (disconnected from Miele’s mainstream appliances) description of RemoteVision. But there’s still no mention of the SmartPhone app.

Why would they let such a cool feature go unpublicized?
