Because of googles enshitification I have stopped using voice to control my home entirely. I invested in many scene remotes and built extensive automations. I’ve come to not miss voice control at all. But here’s to you that want this either for assistive needs or just because. I just need to get a few more local TTS speakers for alerts.
I’ve had my eye on this for a while, haven’t dropped the dough on a PCB order

A hackable AI home assistant platform using the Google Nest Mini (2nd gen) form factor, consisting of:
a custom PCB designed to be a drop-in replacement to the original, using the ESP32-S3 for audio processing
a server for handling the transcription, response generation and Text-to-Speech from multiple devices on the same network
