When we upgraded our appliances, the "smart" or "wifi-enabled" ones were specifically avoided like the plague. "Dumb" appliances - especially fridges, for some reason - are becoming hard to come by, but they do exist. Electrolux, KitchenAid, even LG all make some no-frills models that can save both money and frustration. Hopefully those companies continue serving the "luddite techie" market.
