Technology Highlights

• The invention projects an arrival time of the mobile device user to correspond a recovery time period with an environmental attribute means in non-operating and operating operative modes, for control of at least one environmental attribute that is non-consumable (e.g. indoor temperature) or consumable (e.g. heated water) between a setback level and a setpoint level, and scheduling housekeeping of service provisions.
• The invention's operative modes of devices related to the monitored space are changed in accordance with detected or expected presence of intended users.
• The invention is involved in the provision of non-consumable or consumable environmental attributes, human resource allocation and house watching a monitored space.
• The invention obtained each tracked user's time of departing, and time of arriving at the hotel with the user's proximity log, yields the estimated number of total users at the hotel during any time of the day and projects the settings of the temperature and the reserve volume in the hotel water heater system of environmental attribute means.
• The invention provides a solution to a common problem of the comfort level often being the setback temperature either too far away from the setpoint temperature to provide satisfactory comfort when someone returns to the unoccupied monitored space, or too close to the setpoint temperature to achieve adequate energy savings.
