Hi,

I have a few of these devices "Fibaro Smoke Sensor FGSD-002"

ZW-Version 6.51.03
Device-Version 3.01

I can not integrate them with the SECURITY class. I do not want to use them unencrypted. Could it be, that the Device-Version / Firmware version is too old? Unfortunately I do not have access to the fw-bins and I do not own a fibaro controller.

Does someone have more insights?

Thank you

This is one of the first ZW500 devices. I fear it had no Security implemented at that time

Ok, unfortunately your are probably right Thank you.

6.51.06 Fibaro FIBARO Smoke Sensor 3.03 Notification Sensor

Little higher version, but with security.

Thanks @enbemokel - helpful information.
