I am looking at getting the voice thing from nabu casa.

I have seen people mess witb nests and echos and similar products either through jailbreaking or full on board replacements and I am trying to pick a lane.

I just want to be able to do simple commands for now but if I got the premium it would sit in the comms cabinet floors away from me. Does it act as just a brain and I can attach any mic, echo, nest to the system after?
