You could buy whatever and simply no connect it to anything?
I understand. Some company should made "dumb-smart" appliances with programmability and other smart stuff but without the hassle of "smart" things, no conections, no firmware update, no security issues.
In my old place I had a programmable voltage protector for the first water heater (back when I could actually afford not being my own plumber) and it was sweet and perfect. I could program any day or hour to be on/off and also could manually turn it on for any length of time I wanted up to 24 hours (it remembered the last time set) or indefinitely on or off and it accomplished all that with only 5 buttons and a pretty simple, calculator style, no backlight screen.
It was programmed to turn on the water heater for two hours right before dawn and then two hours starting at sunset. It was all it was required and I can't see how internet connection would have improved it in any way. In fact if any improvement would have been required it could have been a backlight and that was about it.
It was a good device, not as clumsy or random as a wifi coverage; an elegant appliance for a more civilized age.
Then I remember my brother in law smart tv, lots of loading time, crappy software blunded in, slow as hell and no memory to install beyond a couple of things truly necessary/useful. Surely newer smart tvs are better and improved in all those aspects, but I just don't see the point, specially with the seemingly arbitrary obsolescence forced by the software updates (ie no more youtube, news or netflix for you, sorry buy a new one). It think is better a dumb tv with a laptop or a micro pc installed on the back.
