I think that I am changing my opinion on "smart" appliances.
Now that I am thinking more about electricity demand shifting, and moving usage to hours when I am asleep, being able to conveniently turn something on without me being in front of it would be welcome.
On-device controls are not intuitive, and are all (in terms of the appliances that I have) delay based, rather than absolute time based.
I'd prefer local communication, with no need for a third party server, for sure.
(Smart plugs and finger bots can only go so far.)
