All of these solutions I've seen still have manual override. If my nest isn't connected to the internet, I can still go over to it and turn it and the heat will come on (or go off). If my smoke detectors can't talk to the internet, they'll still work like a regular smoke detector. And even control my Nest through it's own mesh network (If I want them to). I can't speak from experience, but I'd bet that my garage door remote will still operate the door even without a wifi network to sell my open/close times to the highest bidder. Regardless, I don't think Craftsman is interested in my garage door habits; they're interested in selling me a new garage door that I otherwise wouldn't think I'd need to upgrade. Smart home functionality is just one way to get that sale in. And it apparently works.
