Abstract: A device assembly including a supply connection adapted to be electrically connected to a power source; a microcontroller; a sensor system adapted to measure at least one environmental parameter; and a supercapacitor. The device assembly has a first operating state, in which power is supplied by a first power supply link from the supply connection to the microcontroller, and a second operating state, in which power is supplied by a second power supply link from the supercapacitor to the microcontroller, and the microcontroller is alternately in an inactive mode and an active mode.
