Cars are also relatively expensive. iot products seem more in the disposable and non-essential space. You can always just throw it away without much inconvenience, so why put a lot of effort into the purchase process? Heck people don't even seem to care much about cell phones and keeping them up to date (iPhone and Nexus aside). And cell phones are far more important than lights etc.
As for the last paragraph, perhaps certification instead of standards? The equivalent of UL (Underwriters Laboratory) would work, but it would need to suit the nature, prices and timelines of these products. At least consumers would then know to look for the logo.
While there could be conventions for REST endpoints, I'm sceptical they would be of any use. The devices by their nature are special purpose (rather than general) so there would be a lot more domain knowledge needed to make sense of them. Additionally making them robust against general clients versus only in-house ones is a lot more work. The general ones would attempt to do nonsensical or potentially even harmful settings, and so would require more engineering spend to protect against.
