Hi all,
I'm starting from scratch and like to setup a system running both 433MHz(RFM69) and 2,4GHz(NRF24).
The reason is that I want to be able to make my own DIY mysensors sensors and actuators in parallel of using standard units in common stores (Nexa, Ikea, etc).
There is also a good chance that I'd like to play around with BlueTooth and z-wave later on.

I'm leaning towards running OpenHab. (Alternatively Domoticz or HA).
(I have already a Synology NAS, a Z-stick and an R-PI 3 laying around.)

So - How do I go about things? Browsing the forum I can't come to any conclusion.
How would YOU set it up in the easiest, most stable and flexible way?
Using all arduino? RPI? Where to run the controller? Separate GWs for each protocol/freq?

An idea:

• RPI or Synology running the controller (OpenHAB)
• GW1: Arduino Nano + RFM69, connecting to controller via USB
• GW2: Arduino Nano + NRF24, connecting to controller via USB
• Z-stick connected to controller via USB
