Systems and methods for controlling the ambient temperature within a region or zone of a building are disclosed. A system comprises a thermostat, one or more sensors placed throughout an environment, a computing cloud, and a remote mobile or desktop device running a software application (“app”). An end user may interact with an app running on the mobile device or desktop. The app may display the current conditions in a house and allow the user to select specific temperature sensors located throughout the house which the user wants to monitor and control. This selection of one or more temperature sensors is communicated to the computing cloud, and the computing cloud sends commands to the thermostat to monitor the user's selected temperature sensors for controlling the heating and cooling of the house.
