What happens in the event of a power grid failure (configuration data and status of the By-me system)?

Even after the charge for both the home automation and alarm systems has completely run out, all the configuration data of the various devices and the control unit remain stored in the devices themselves. The control unit also has an internal backup battery inside that allows retention of the date and time.in memory for 24 hours. Once power supply is restored, the system returns to the same state in which it was before the blackout.
