Homematic WiFi Gateway (switched from FHEM to Home Assistant)

Hi everbody,

I want to switch my home automation System from FHEM (perl based) to Home Assistant.
I have several homematic (not IP) components.
For controlling those components I use a wifi Gateway. It is an HM-MOD-RPI-PCB connected to an ESP8266 via Uart running an esp-link software. In FHEM there is a module for controlling everything (HMUARTLGW).
To be completely honest, I don’t exactly know how this setup works.
I am wondering if it is possible to use my setup with the wifi Homematic Gateway in Homeassistant?

May someone with more expertise might help here. Thank you!
