Yeah, it's frankly ridiculous that "smart" devices need internet access. Why shouldn't my smart oven behave exactly like my Brother printer? There's no reason my oven needs access to the internet, it can do everything it needs to do on my local network. My phone should be able to connect directly to it via a scan of the local network subnet or using any number of service announcement technologies that already exist.

And it makes these devices worse. I should be able to control my oven using a simple REST api and home assistant. The fact that in order to interact with my oven with a home assistant I first have to reach out to my manufacture servers is just insane. It's an oven. It only has so many sensors and nobs to twist.

About the only grace I give these manufacturers is the fact that google and apple both make it an annoying pain to maintain applications in their app store. A manufacturer can't simply drop "oven app" once and expect it to be available on the store forever. But that too should be solved with the same regulation that says "Ovens, refrigerators, washing machines, thermostats, and doorbells must not connect to the internet". We can teach the world about VPNs if they want remotely access their devices.
