>>Do you have WiFi at home? Most people do. In the case of this IoT dishwasher I suspect it's WiFi only, no wired option available.

No wireless here... or intermittent wireless for an hour or 2 per day, e.g. to download OS updates or big apps. Instead I commissioned 5km of network cable during a big renovation. But this Miele dishwasher has a long network cable, with instructions that it's only to be connected by an approved technician. I wonder whether this researcher plugged it in himself without the protective settings Miele intends.

>>You might get the impression I'm not a big fan of WiFi for LANs ;)

Nor am I. Multiple wired POE ports in every room.

>>- 3rd-party mediated service (similar to LogMeIn) allows a user to control their device from anywhere worldwide

I can do that now for my home automation...even if the internet is down it can listen on the POTS phone line for a particular sequence and intercept it for secure old-fashioned modem comms. But I've never used that. Instead I dial into VPN and use the native app, inside the firewall.

>>Something like that would be a halo/gee whiz feature useful for marketing purposes. Some of it might even be useful if properly implemented. But privacy and security seem to be the last issues addressed, if they're addressed at all.

As noted, I wonder whether Miele had an opportunity to set this up properly, or whether the researcher plugged it in himself and confirmed that security wasn't yet implemented.
