NAS vs Raspberry Pi which is better

I’m thinking about getting away from Smartthings due to various issue, outages, and recent lag due to it being cloud based.

I have an Open Media vault server that I can run Docker on. My question is, if I buy a zigbee/Z-Wave combo usb module, how do you get the Home Assistant container to talk to it? Is there a way to map it to the container?

If this is possible it would save me from buying a Pi.

Is there a best practices post around here somewhere?

A list of common add-ons required to run zigbee and Z-Wave devices?

Thanks,

yes you can map usb ports into docker.

 --device=/dev/ttyUSB0

Add line to the docker command.

So based is the consensus that running in a Docker vs. spending the money on a Pi would be the way to go?

Can someone recommend a combo zigbee/Z-wave dongle?

Thanks
