Hi Rowland,

I fully agree with you about the stupidity of smart things. They make 
life miserable (looking for a new dishwasher from one premium brand, 
there were no models without WiFi)...

It makes no sense in upgrading the hardware in the controllers, and you 
cannot run Windows 11 on a PC with a Celeron 180 MHz, and 64MB of RAM. 
And those controllers really cost serious money.

The network is sandboxed, I would never dream of opening Pandora's box. 
And guess what? No USB. Floppies, or custom "portable" HDDs.

Thanks for the information, most useful.
