You may or may not be amazed to find that the programmable thermostat and remote management options are ridiculously weak. We literally had thermostats from Bayweb on order, when we saw an article about Nest thermostats. There is little that I can write that hasn't already been said by the authorities: NYTimes, David Pogue, Macworld.
We will no longer be arriving to a freezing cold house (we keep it at 50 when not there). We can adjust them temperature from our phones in the car, or simply before we leave the office. (update: we have radiant heat, it takes a full day to get up to temperature from 50 degrees.)
It works, as it should, right out of the box, no instructions needed. It took about 10 minutes to install (thwarted only by the depth of the sheet rock before I hit a solid joist in the marriage wall).
These photos leave a bit to be desired, it was 630am and my 16 month-old helper was buzzing around my feet.
After turning the power back on, I connected to our wireless internet connection and the unit self-updated.
It then backed itself up.
It asks for your zip code.
Then setup was complete.
