I see this as two different things. Personally I have an automation setup so that if it’s dark out and I get home, lights turn on for me to go into the house both inside and outside the house. The outside ones turn off after 5 minutes and the inside, most after 10 minutes. That’s easy to do and can be in place for everyone.
As for door locks, that will never happen and I can see why and kind of agree. i wouldn’t want my car to be unlocking the house doors… that’s a security issue for some… I know it’s a button but, I see them worrying about It. And I defiantly wouldn’t want that happening till they allow for a way to choose on CarPlay which garage door to open… that’s first imho…
