Can you login to the device? And is the device in the same network range?
Is there a extra router in your network?
What version is your motion sensor?
Mine is Firmware External Version: V1.20 (version A1 Europe)
Firmware Internal Version: V1.20b10
Witch is strange because the latest version seems to be: Firmware Release notes missing 1.07 date 15-5-2015
