I almost purchased a Nest thermostat. It was what I thought I wanted, but I was always curious why a single-point thermostat would be significantly better than a plain WiFi thermostat. I couldn't come up with a good answer, so I purchased a $99 Honeywell WiFi thermostat. It worked perfectly.
Now that I've focused on de-Google-fying my life, I'm glad I didn't get the Nest. I don't need Google knowing when I'm home and when I'm not. Paranoia? No, just trying to keep my private life private.
With my new home, I got an EcoBee3 thermostat because of its ability to use multiple sensors around the house and intelligently adjust the temperature. That it's HomeKit capable is just icing on the cake. And my information isn't being sent to the Google collective.
