As the title said, I’m curious how these feature and interface updates apply. Probably my only smart light bulb will receive an update to allow the daytime color temperature things ordered by HK. But which of my devices will need to be updated to fit this? Is it enough to have only one iPhone on your account updated to iOS 14? Do I need to update the iPad I use as a hub? Do I need to update ALL iOS / ipadOS devices on the appleID to which my home hub is connected?
I’m asking because I’m jailbreaking my iOS devices and most likely I won’t upgrade to iOS 14. But I have a few spare parts that can be upgraded if that’s what it takes to get the new features.
