--000000000000a92bd405f76be4df Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable 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.
