Lower temperatures than 0°C will noticeably reduce capacity of energy store, but temporarily only Note 2: Recharge energy storage after 36 months in total darkness to maintain its performance. ETHSx is a wireless temperature & humidity sensor for EnOcean systems. It is solar pow- ered maintenance-free ETHSx periodically measures temperature and humidity of its environment. Significant changes in the measured values are reported immediately, regular updates (signs-of-life) are provided in intervals. The small housing can be easily attached to walls or furniture using the included adhesive pad. Sin- gle pack comes with metal stand. the sensor can be positioned on horizontal surfaces and the up- per square cap can be replaced by additional in- cluded triangle cap.
