Privacy matters to me, but of greater import is the safety of my aging mother. For her to be able to turn on and off lights, lock and unlock doors, should not require dependence on always on lights or internet, or 90's era smart home setup. Additionally, what I describe is not essentially the domain of expensive corporate environs, or at the very least it should not be.
In this instance, there is an echo plus device, which is capable of controlling "offline" any device for which it is a hub. In theory, if all the devices in my Mother's home were connected to that hub, my query is answered. The concern is for a less proprietary method and if no one sought such, let all be defined by corporations.
The conversation is not intended to be philosophical, but technical, and while inexpensive lighting is obvious, it is not inclusive of the smart home elements I seek to keep accessible in this instance.
I presume that Amazon will ultimately increase the compatibility elements regarding its hubs, the interim may or may not be such that a privately managed server could be profitable or simply of intellectual interest sufficient to make happen. Think in terms of the universal remote controls and the programming behind macros that greatly increased the capability of ir controllable devices...and thanks to people like powerpig, changes occur based on need and not just immediate market access.
Anyway, thanks all for the conversation and let's see what happens.
