What seems interesting to me about many of these (all the HVAC, home automation stuff) is that a device with a voice interface sort of seems like a local maximum in terms of usability. You're spending lots of time getting info from Alexa and then telling her what to change to keep the environment ambient.
I would expect that in the future, home automation does all the regulation for you without any interaction. You set up a bunch of configuration in advance, and maybe train the device a little bit initially on things like your temperature preferences (because we think we want a certain temp, but actually usually find it slightly too warm or whatever). Then you almost never have to make changes, let alone expend your executive function on deciding what instructions to give the devices.
