I got new appliances a couple weeks ago and they’re all “smart”. Turns out a smart microwave just sends you a phone notification when it’s done. By default.
As someone with multiple people living in the house, I can confidently say this is the dumbest “smart” feature ever. Promptly disabled.
My stove won’t preheat, I guess because it’s a safety issue. Apparently you can set a remote start capability ahead of time that gets reset if you open the over door. But I’ve never tried it, since that seems like a lot.
