Patent ID: 8688284

Claim:
A method for switching at least one electrical consumer in a building wherein the at least one electrical consumer is supplied with electrical current from at least one electrical current supply, at least one power contact is switched by at least one switch from the electrical current supply to the electrical consumer, the electrical consumer and the switch are each controlled by at least one network node, the network node receiving via at least one radio network at least one control signal, comprising: detecting an identity of at least one user with at least one identification sensor; generating at least one identification sensor signal from the at least one identification sensor for a recognized identity of the at least one user; transmitting the at least one identification sensor signal from the at least one identification sensor via the at least one network node in the at least one radio network, the identification sensor signal identifying the at least one identification sensor as a beginning point for a route in the building; generating at least one destination signal for the transmitted identification sensor signal; ascertaining at least one building door in the building for the generated at least one destination signal, the destination signal identifying the at least one building door as an ending point for the route in the building; ascertaining by the at least one identification sensor at least one route time from the beginning point to the ending point in the building; performing a check to establish whether prior to the at least one route time expiring a door sensor signal of a door sensor of the at least one building door is transmitted; in the event that the door sensor signal is not transmitted, ascertaining at least one electrical consumer on the route from the at least one identification sensor to the at least one building door; ascertaining at least one activation signal and a network address of a network node of a switch of the at least one electrical consumer; generating the at least one activation signal and transmitting the generated at least one activation signal and the ascertained network address to a network node of the at least one electrical consumer; and transmitting the at least one activation signal from the network node of the at least one electrical consumer to the network address of the network node of the switch.
