All things that have worked just fine on cars for like at least a decade before the internet was ever invented. You are describing the exact functions of a key fob. They can even open the truck without the Internet!
That’s exactly what I use remote start for. Just leave your car set to 68 or whatever and then when you remote start it will come up or down to temp. Even on my cheapass Chevy that’s 10 years old I can remote start it (including the HVAC) and also hold the “unlock” to start the defroster. Now I can’t actually change the temp the system is set at without getting in the car, thats true, but that’s a real edge case for me when I can just leave it set at room temp pretty much year round. Even the seats and steering wheel will heat up if I left that on beforehand. But maybe you do have a real need to tweak the temp and A/C values on the daily where you live, rather than just have the car resume where you left it at, I wouldn’t know.

They make it go through an app and a cloud service on purpose these days so they have an excuse to upsell you on a subscription.
I’ve never seen a fob be able to set climate controls. Either way, I’d rather control my own cloud for the car through home assistant
