the thermostat at least one processor compares the outside temperature at at least one location and at least one point in time to information reported to the remote processor from the thermostat the processor uses the relationship between the inside temperature and the outside temperature over time to derive a first estimation for the rate of change in inside temperature assuming that the operating status of the climate control system is u201c on u201d the processor also uses the relationship between the inside temperature and the outside temperature over time to derive a second estimation for the rate of change in inside temperature assuming that the operating status of the climate control system is u201c off u201d the compares at least one of the first estimation and the second estimation to the actual inside temperature recorded inside the structure to determine whether the actual rate of change in inside temperature is closer to the first estimation or the second estimation application_number US 201414285384 A description fig1 shows an example of an overall environment 100 in which an embodiment of the invention may be used the environment 100 includes an interactive communication network 102 with computers 104 connected thereto also connected to network 102 are one or more server computers 106 which store information and make the information available to computers 104 the network 102 allows communication between and among the computers 104 and 106 presently preferred network 102 comprises a collection of interconnected public and or private networks that are linked to together by a set of standard protocols to form a distributed network while network 102 is intended to refer to what is now commonly referred to as the internet it is.
