nvenergy.com/coolshare - the power company wants to give me a nice programmable thermostat so they can tell it when they need it to conserve power draw. Besides the fancy thermostat, I get to access it via their website.
But how does it communicate?
It doesn't seem to need an I'net connection nor a telephone connection so how does the central big bro' talk to the thermostat?
I can find very little on the technical aspects involved. Can anyone help me understand the what and how here? Caveats or concerns?
