I’m not able to integrate my Eltako STM 550 (Enocen) battery free humidity and temperature sensor in my HA. In the documentation the EEP Typ A5-04-03 is not supported. Because this is a very good sensor which do not use a battery for operation because it uses a solar panel which spend enough energy only with daylight, also inside buildings.
It would be nice to get more supported enocean devices to the ha platform.
I would appreciate if someone would develope a support for the STM 550.
