How secure is EnOcean technology against manipulation?
Basic methods for security against manipulation are already implemented in the EnOcean system architecture: Each transmitter has its specific 32 bit ID as a fixed part of its transmitted telegram. This ID cannot be copied with the bidirectional EnOcean module. Further measures for greater security such as rolling code and encryption are in preparation. Why does not EnOcean use battery-backed wireless switches? For EnOcean the reliability of products is an absolute must. The disadvantage of batteries is their self-discharge, meaning that they usually have to be replaced after a few years. That would involve removing a wireless switch or sensor from the wall or wherever to service it. For reliable operation, especially in buildings with a large number of wireless switches for instance, you have to schedule the battery replacement cycle in good time so that those units with the most intensive duty always have sufficient energy reserves. As a result, with the majority of the batteries more
