My house didn't play nicely with my Nest. I got a new Furnace and AC and had them install a Nest. It started acting weird. We replaced it with a low-tech Honeywell while trying to get it figured out. I then replaced the Nest thinking maybe it was faulty. I took a photo of the wire layout for the Honeywell and made sure I did the proper layout for the new Nest. It worked fine for a few days and then one day I came home to a 110 degree house! The Nest reported that things were 70-whatever. I then replaced it with a Wi-Fi Honeywell (not their Nest competitor) and that one has worked fine since. It was a very scary experience. I won't be trying a Nest again.

Identical experience here. Installed Honeywell RedLINK and finally my problems went away. Ditto Honeywell wireless security, also works great. There's SO MUCH crap out there, and the wave hasn't even started yet.
