Enocean pi 868


I have a smoke detector setup in my home from Aico which uses RF on 868 MHZ. I also have a ENOCEAN PI 868 transceiver and a spare raspberry pi in my drawer.
I was hoping that i could use the transceiver to replay the RF data to home assistant and then make my smoke detectors “smart” by integrating them as a switch in HA.
Has anyone got any ideas on how this could be done? I looked at installing FHEM on my spare pi but i think this may be overkill when all i really need to do is replay any RF data.

many thanks
