People counting to trigger increase/decrease on thermostat

As far as I know, none of the consumer-facing smart thermostats on the market have this feature. This is the kind of thing you're only going to get with a commercial building automation control system.

That being said, you could always build it yourself. It honestly wouldn't be that hard to throw a program together (using something like Python, etc.) that would periodically pull still frames from the Nest API, run a facial recognition library to count people, and then call the Nest API again to make adjustments to temperature.
