Not only does the Nest ignore my preferences, I think it actually lies about the current temperature.

Example:

Setting is 72, reading is 73. AC is not on, I guess the thermostat is trying to save energy. I lower setting to 71, reading instantly drops to 72! I don’t think it’s a coincidence, this has happened several times.

This can be explained by hysteresis [0], which all thermostats use to avoid cycling the A/C too fast.

But the second part where the reading drops instantly is strange. Sounds like some kind of software heuristic where they're trying to make the user feel more comfortable about the hysteresis interval. Or something.
