You know, This kind of shit happens so frequently anymore that if you're dumb enough to buy things that, for absolutely no reason, requires an internet connection and/or an app.. Then you deserve what you get.
"Its not my fault that I bought a stupid device for $$$Texas more than a normal product and created the market for it, its their fault for making it available for me to choose to buy!"
It's sometimes hard to find, I needed a new stove, all the ones I could afford and that had what we needed had a fucking internet connection. I fucking hate it.
Find a scratch and dent place near you. Thats pretty much where I get all my appliances. Often the cosmetic issues are not even noticable, and if they are, they are often in a place that you wont see since they'll be hidden by cabinets or what have you.
I'm quite remote, there aren't very many options where I am, otherwise that would have been a great option. But whatever it was, it would have had to be compatible with propane which makes it a bit trickier.
I'm not being sarcastic or attacking or anything, but I find that hard to believe. I spent 2 minutes before posting this looking at ranges and ovens (I dont know if you're talking about a complete stove unit (burners on top of an oven in a self contained stand alone package) or the oven unit that mounts into a wall, so I looked at both in that time) and I found tons that were cheap (well, cheap as far as these devices ago at least) and none of them had smart connectivity.
It wasnt until I was getting into the high cost items that were $5000+ that smart stuff started appearing.
Almost all ranges are propane compatible but will require the effort of installing the (included) propane conversion kit. The exception is Frigidaire, where the kit has to be purchased separately.
FYI, most of Whirlpool's range lineup (including Amana, Maytag and the non-"Pro" KitchenAid models), all of Frigidaire's range lineup, most of GE's base line range lineup (not Profile or Café) do not have Wi-Fi capability. It's mostly Samsung and LG pathologically putting connectivity into everything they make.
What features did you need that you couldn't avoid connectivity? I just queried my own product database and came up with 202 models that are LP compatible without purchase of a kit and do not have Wi-Fi capability. 261 if you're willing to countenance Frigidaire. And even among most of those that do have connectivity (KitchenAid's "Pro" models being an irritating exception) you don't need to connect to Wi-Fi or use the app for any functionality of the appliance; it's just an extra.
