I build Google Home Assistant for Armbian (S905x) based on NodeJS (because Python eating more resources)

For installation you need:

1. NodeJS 14 and PM2
2. Microphone and Speaker
3. Device ID and Device Model ID (Create it on Google Cloud Console)

PM2 monitoring (Start -> Mic -> Detector -> Google Home Assist -> Audio -> Terminate)

1. PM2 started the app
2. Detecting wakeword/hotword
3. If wakeword/hotword detected, send your voice to Google Assistant API
4. Google Assistant will respons your voice
5. App terminated and PM2 will restart this app

I don't know the efficient way to run this app.

Add all of your configuration on .env file

DEVICE_ID=YOUR_DEVICE_ID // Obtained from GCP
DEVICE_MODEL_ID=YOUR_DEVICE_MODEL_ID // Obtained from GCP
LATITUDE=YOUR_LATITUDE //
LONGITUDE=YOUR_LONGITUDE // 
MIC_HW='plughw:1,0'

For MIC_HW, you can get from arecord command

$ arecord -l
card 1: Device [USB PnP Sound Device], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice # 350: subdevice #350

You can see is the card number is 1 and device is 0 so your plughw is plughw:1,0

Install audio dependencies

sudo apt install libmagic-dev libatlas-base-dev sox libsox-fmt-all build-essential

Install alsalib or pulseaudio lib for compiling backend

sudo apt install libasound2/pulseaudio-libs-devel

Install speaker-arm64 with your audio backend (example pulseaudio)

npm install speaker-arm64 --mpg123-backend=pulse/alsa

Install all dependencies

npm install

Install pm2

sudo npm install -g pm2

Run with pm2

pm2 start index.js
