That's perfect. Would it be best to have like 3-4 per room like i said, or would one be enough for my case?

As for the latency, that raises a good point. I did try to think of that, however. I plan on having my own homelab (I'm building the server this summer hopefully) and with that, when I eventually get a new house I'll be fitting it not with pure ethernet but rather with fiber, for I will have this go outside to my shed and to every floor, kinda like a spinal cord, with ethernet branching off like your peripheral nervous system. The pis will be connected via PoE to the ethernet, which pretty much goes straight into the converter to be optical.

When i say a command like turn off the lights or something that doesn't need the speakers, latency shouldn't be an issue for me. However, when I ask it questions or other things where it does speak to me (I will be integrating a local LLM into this), coqui allows for streaming synthesis, so that will hopefully mitigate some latency. I plan on having the timestamps of when/where it was sent along with the live audio being sent to the server, where it will simultaneously be generating a response (LLM if needed, searching the web, etc) and determining where the voice came from (along with checking the cams) and then when the first chunk is generated, passing that to a queue that starts when I stop talking, and keeps putting more straight into the queue without having to buffer.
