Re: Bhyve process consumes way too much CPU

Are you talking with me ? I can install Home Assistant only on the hardware
that I already have. Actually the best piece of hardware that I can use for
my project (installing the chat gpt module on Home Assistant + a speech
recognition software to give a voice to chat gpt) is the nvidia jetson
nano. And If I remember correctly,it supports only Ubuntu. I can do the
same on my Workstation,but I prefer to have the ability to move the smaller
nano within a plastic container. At the end of the day It will be almost
the same as a vocal assistant,but uch more programmable.
