STEP5. Installing Magic Mirror Modules

Go to modules directory and install the MMM-Hotword

cd ~/MagicMirror/modules/
sudo apt-get install libmagic-dev libatlas-base-dev sox libsox-fmt-all
git clone https://github.com/eouia/MMM-Hotword.git
cd MMM-Hotword

./node_modules/.bin/electron-rebuild

STEP6. Configure Google Assistant Module

Generate Other credentials with the OAuth Client ID in Create Credentials
Download generated OAuth client ID in json format
Move the downloaded OAuth client ID to modules/MMM-AssistantMk2/credentials.json

mv ~/Download/cre.... credentials.json

Run auth_and_test.js to verify the generated client ID

node auth_and_test.js

Accept the client verification process and copy and enter your Google account key
Move the generated token.json

mv token.json ./profiles/default.json

STEP7. Edit Google assistant module config

Open the Magic Mirror configuration file with TextEditor and modify it with the contents of github

Install USB Mic. and Speaker

https://github.com/makepluscode/rpi-tips/tree/master/001-bringup-audio-and-mic

Wow this is a great tutorial, and video. I am going to add this to my mirror. Can I ask where you got your USB mic and speaker combo from?

I especially liked how you showed the troubleshooting, and corrections in your video. So many people edit out the hurdles. Kudos to you my friend! A++

leej00

Thank you for the elaborate instructions, everything for me went well until I’ve noticed that the default modules (calendar, complements, news feed) seem to disappear after some time. Did you run into similar issues?

@leej00 hello mate

how did you configure the last part i.e.

STEP7. EDIT GOOGLE ASSISTANT MODULE CONFIG
Open the Magic Mirror configuration file with TextEditor and modify it with the contents of github

there is soo much information on github that needs to be added on to the config.js, which part of it did you add to your config.js? can you please share it?

I get the google icon on my mm but when I say “Ok Google” nothing happens"

Thanks.

numb3rs

A few things you can do:

Add your location inside the config.js under the module call. You can find this info inside the CONFIGURATION.md
i.e.
// — ESSENTIALS / modifying for your environment might be needed.

Use: https://www.mapdevelopers.com/geocode_tool.php

deviceLocation: {
  coordinates: { // set the latitude and longitude of the device to get localized information like weather or time. (ref. mygeoposition.com)
    latitude: 00.0, // -90.0 - +90.0
    longitude: -00.00, // -180.0 - +180.0
  },
},

With MMM-Hotword, using USB mic (plughw:1) you need to use the following:

//Hotword Module
{
    module: "MMM-Hotword",
    config: {
      record: {
        recordProgram : "arecord",  
        device        : "plughw:1",
      },
      autostart:true,
      onDetected: {
        notification: function (payload) {
          return "ASSISTANT_ACTIVATE"
        },
        payload: function (payload){
          return {
            profile: payload.hotword
          }
        }
      },
    },
  },
{
		module: "MMM-AssistantMk2",
		position: "bottom_bar",
		config: {
		record: {
        recordProgram : "arecord",  
        device        : "plughw:1",
      },

      notifications: {
        ASSISTANT_ACTIVATED: "HOTWORD_PAUSE",
        ASSISTANT_DEACTIVATED: "HOTWORD_RESUME",
      },
deviceLocation: {
      coordinates: { // set the latitude and longitude of the device to get localized information like weather or time. (ref. mygeoposition.com)
        latitude: 00.00, // -90.0 - +90.0
        longitude: -00.00, // -180.0 - +180.0
      },
    },
                
}
},

It works. Thank You! I am using the PS Eye as suggested in other forms. My audio out is still set to HDMI because im staging on my TV.

LPT: Add the following to the MK2 module config so the screens dont toggle so fast:

screenDuration: 5000, //this is milliseconds

@leej00
Testing this now to see if I get the same results.

@makepluscode
Can confirm all modules disappear besides the default weather module.

I have a YouTube playlist playing, and I can still hear the module playing through the speakers, but visually it is no longer there.

If I give it a keyword voice command it is listening for it will draw the modules again.

Another observation is every time I give it a voice command it starts my playlist from the top.

@bachoo786 say “smart mirror” or “snowboy”

You can also read more on the .umdl and how to obtain a custom .umdl here:

@makepluscode
Hello first of all thanks for the great tutorial!
Unfortunately I’m stuck with the last step (installation of the microphone)
When I enter the command “vi ~/.asoundrc” I get the following message:
0_1552146497267_IMG_1216(2).JPG

I ask for help
Greeting Fabian

Sahil

@Fabian
Type sudo nano. asoundrc in command prompt
Then paste your code there.
To save that code press ctrl+X, then Y and then enter.
You are good to go
