Abstract

The invention relates to a method for switching on and off a night mode of a heating and/or air conditioning system, wherein an energy consumption of the heating and/or air conditioning system is reduced when the night mode is switched on and increased when the night mode is switched off. It is provided according to the invention that with a smartphone an activity of a user of the smartphone is detected, that with program code an activity state of the user is inferred when an activity is noticed and a state of rest of the user is inferred in the absence of activity, wherein the program code is stored in a non-volatile data memory, and that electronic control means switch on or off the night mode as a function of whether a state of rest or an activity state of the user has been noticed. The invention also relates to a corresponding control apparatus.

9. Method according to claim 1, wherein:

the durations of states of rest of the user are detected and stored as reference sleep durations and/or

clock times at which a change from a state of rest to an activity state is noticed are detected and stored as reference getting-up times,

to switch off the night mode before an activity state of the user is noticed the switching-off of the night mode is carried out as a function of a ratio of a current sleep duration to the reference sleep durations and/or a ratio of the current clock time to the reference getting-up times.

10. Method according to claim 1, wherein:

a duration of at least one state of rest of the user is detected and stored as a reference sleep duration and/or

when a change to a state of rest and when a change to an activity state are noticed are stored as a reference going-to-sleep time and as a reference getting-up time,

a squelch time, within which a change between the activity state and the state of rest is categorised as implausible, is determined from a clock time of the last change between an activity state and a state of rest and also from the reference sleep duration and/or the reference going-to-sleep time and the reference getting-up time, and

a switching-on or switching-off of the night mode is only permitted outside of the squelch time.

11. Method according to claim 1, wherein:
