1. A thermostat system for monitoring and controlling temperature of an environment, the thermostat system comprising:
a controller configured to:
predict a temperature of the environment for a plurality of time steps as a function of temperature setpoints for a thermostat;
generate the temperature setpoints for the thermostat by performing an optimization subject to a constraint on the temperature using a utility rate; and
provide at least a first temperature setpoint of the temperature setpoints to the thermostat via a communications network;
wherein the thermostat is configured to drive the temperature of the environment toward the first temperature setpoint during a corresponding time step of the plurality of time steps by operating HVAC equipment to provide heating or cooling to the environment.
