A nest would be a royal pain in the ass for you. even if you set it, it sometimes will try to be 'smart'
I was wondering what all those optional sensors you can place all around the house would be like. But I do like the wifi aspect where you can adjust it while away and that it will sense when no one is there and adjust the temp by itself. While the Duke email only mentioned the Nest when you go to the Duke Store website where they have all kinds of energy saving gizmos for sale they offer other thermostats besides the Nest. Ecobee, Emerson, and other Nests. Lots to think about.
