Configuring new house?

Hallo,
We are building an new house with enocean smart home (eltako), a bticino video intercom, an proxon central heating system, hikvision kamera system with acu sense and unifi wlan hotspots.
What i didn‘t found is the eltako enocean, the proxon central heating system and the bticino video intercom.
How easy would it be to integrate those systems.
What could you suggset as central touch display, maybee with microphone and speaker for the intercom
