The important thing is the main server, that’s the advantage of satellites.
Now I haven’t tried it yet, but with Rhasspy, you had the choice between the satellite doing wakeword recognition (which means that a pi zero 1 would be too slow), or doing it on the server (which would mean permanently sending all audio the satellite picks up to the server, and the extra latency that adds)
A pi3 is really powerful enough for wakeword recognition
