ELV / Conrad Heating Control

Hi,
I have Conrad FHT80 thermostast and actuators to control central heating, 3 zones. Conrad is a badge of ELV a Germany company, supplying heating control it is FS20 controler.
Frequency is 868,35 MHz. Is there suitable RFX unit which would permit interface and control by Vera ???
Did find a post where FHEM a Germany home automation software had been loaded onto Vera. But sound a bit over my head

I noticed on the vera plugin there was selection FS20, is there a 868,35 MHz version

At my knowledge, the 868 MHz version of the RFXtrx is not yet available.
