Wireless multi-sensor for individual installation 80x80x14mm or installation in the E Design55 switch system. With integrated solar cell and CR1632 battery (not included). This multi-sensor has temperature, humidity, lighting and acceleration sensors integrated in one housing. It sends all data via EnOcean radio to the Eltako building radio. The integrated solar cell generates the required energy from the ambient light indoors. This energy is stored internally so that the multi-sensor can also function for several days without light. The multi-sensor has an NFC interface, which allows it to be configured with the free EnOcean Tool app and an NFC-enabled smartphone or tablet. When delivered, the EEP: D2-14-41 is active, which contains the data from all sensors. The NFC interface can be used to change the parameters of the sensors and select individual EEPs: D2-14-40, A5-04-01, A5-04-03, A5-02-05, A5-06-02, A5-06-03 or A5-14-05.
