Method and device for energy-saving communication in building automation

摘要

Method, device and system for operating a device of a building automation system, comprising generating a recognition bit sequence. A particularly energy-saving data transmission is made possible by first transmission of the identification bit sequence 48 in a first time slot A, B, C and at least second transmission of the identification bit sequence 48 in a second time slot A, B, C, which is distant in time from the first time slot A, B, C, wherein the duration of the transmission of the identification bit sequence 48 is shorter than a wake-up interval of a receiver and the duration 46 of the transmission corresponds to the sum of the first and at least second detection bit sequence 48 at least the duration of the wake-up interval of the receiver.
