Need help - controlling EATON xComfort devices

Hello folks,
has anyone had any luck cloning EATON xComfort switches? It is a 868 MHz FSK modulation home automation system, with little to no available protocol documentation. I tried RAW capture and playback with no luck, therefore I suspect, that it uses some kind of rolling code CRC in its wireless protocol, or I just misconfigured something. Any idea how to debug this with FZ, or should I try my luck with my HackRF right away?

The idea is to turn off all lights when I leave our office last, but I don’t want (or has any chance) to configure new switch to the system…

Thanks for any ideas.
