Hardware Configuration: What is enough?

Hello. (My first post).
Can someone here please let me know what level of hardware I need to run the following home automation:
(I’m coming from SmartThings, and I’m thinking about moving to HomeAssistant).
Is a dedicated synology nas (DS212j with SSD) enough?
Is a dedicated raspberry pi b + enough?

I see nothing in your list that requires an excess of horsepower, storage or bandwidth. In my humble opinion… yer good to go.

Dixey: So, I’m good to go with a Synology DS 212J, with a HUBSZB-1 zigbee & Zwave Stick?

Can’t answer about all the stitching together you may have to do but from a hardware perspective, I don’t see any concerns.

@jtmpush18 have you been able to integrate the ZEN06 ?
I am struggling with a very similar device, see HANK Electronics Ltd HKZW-SO03 Smart Plug issue
Thanks
