Abstract:
1. A method of operating a self-powered home automation sun or wind sensor device for detecting the existence and/or for measuring the intensity of a first physical phenomenon, comprising a means for converting an effect of a second physical phenomenon into electrical energy in order to supply the device and a means for determining the instantaneous power of the second physical phenomenon that can be converted into electrical energy, wherein a normal, first mode of operation of the device or an energy-saving second mode of operation of the device is activated according to a value defined on the basis of the determination of the instantaneous power that can be converted into electrical energy, wherein, in the second mode of operation, the self-powered home automation sensor device transmits only status signals, wherein the transmission of the status signals is periodic, and verifies if a condition for a change of operating modes is met, the device having a lower electrical consumption in the second mode than in the first mode.
