Abstract
A thermostat includes a user interface that is configured to operate in at least two different modes including a first mode and a second mode. The user interface may require more power when operating in the first mode than in the second mode. The thermostat also includes a plurality of sensors, including at least one sensor configured to detect a presence of a user within a proximity of the thermostat. The thermostat additionally includes a first processing function that is configured to determine a proximity profile and to cause the user interface to be in the first mode one or more sensors provides responses that match the proximity profile. The proximity profile may be computed using a history of responses from the sensors that are likely to coincide with times where users intend to view the user interface.
