More Hardware possible

[bforpc]

I hear from this wonderful project the first time today. But I have already 2 Kostal Piko (piko 20 and piko 7) systems.
Is it possible, to - somehow - close up to start OpenDTU with my 2 inverters?
Also I have some Victron devices, how looks like with this Hardware?

Or ist it like with almost all others Hardware - close system, close software?
