Im new here, so i already thanks you for helping me

Platform :
Raspbery with the last Raspbian.
RaZberry with v1.7.1-rc1
My problem... I include my Fibaro Motion Sensor, everything is okay, i have the 2 sensors (Temp/Lux), but if the device go to the sleep state, The sensor will never be recognized by the controller... I try to exclude him... but nothing.
If i include them again, the sensor is added but with a new ID...
I think the id of the device are not save... it's possible ?! Somebody have encounter the same issue ?
