I can see where it would be useful in a family situation...would be nice to have the level of access that my phone has as "owner" available to all without them necessarily being able to make changes inadvertently to the setup. Having some sort of always-on access in each room would be nice...during the evening I will often leave phone and watch charging in the kitchen and want access upstairs to do lights or something. The need to have phone or watch on and use that is pretty much my wife's biggest complaint with HomeKit and why she basically doesn't use it. I think I would like a Siri access point in each room with high-quality microphones to accurately capture HomeKit commands...I would really like this to be for the most part basic though...I don't need or want speakers and cameras, etc...make it affordable enough to allow me o get several for different rooms.
